Aug / 04, 2022

Silane coupling agent in silane cross-linked cable compound
Silane XLPE cable material is widely used as insulating material for low-voltage power cables in the wire and cable industry. Compared with peroxide cross-linking and radiation cross-linking, this material has the advantages of simple manufacturing equipment, convenient operation and low comprehensive cost in the manufacture of cross-linked wires and cables, and has become the leading insulating material for low-voltage cross-linking. As an inorganic non-metallic material, glass fiber has the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Commonly used in composite materials such as reinforcing materials, electrical insulating materials and thermal insulation materials. However, the glass fiber has a large surface and is compatible with resin, which greatly reduces its filling effect. In order to improve the bonding force between resin and glass fiber, and improve the strength, electrical properties and weather resistance of glass fiber reinforced composites, it is necessary to modify the surface of glass fiber. At present, the most widely used surface modifier in glass fiber surface modification is silane coupling agent. The main varieties are: vinyl silane, amino silane, methacryloyloxy silane and so on.   Vinyl Silane Coupling Agent Crosile in Paint Adhesive and Fiber Glass Vinyl silane refers to an organosilicon compound with the chemical formula CH2=CHSiH3.

Petroleum Resins in Rubber Adhesive - Tackifying Resin

Jul / 26, 2022

Petroleum Resins in Rubber Adhesive - Tackifying Resin
Petroleum resins used as tackifying resins can be divided into three categories according to their chemical composition: aliphatic, aromatic and alicyclic. Among these three kinds of petroleum resins, C5 series petroleum resins and alicyclic petroleum resins have the advantages of light color, good compatibility with natural rubber, heat resistance, oxygen and light aging resistance, storage stability, etc., and are therefore widely used. Used as a natural rubber pressure-sensitive resin. Adhesive tackifying resin. Although C9 series petroleum resins are cheap, due to their high polarity, they have poor compatibility with natural rubber and can only be used in rubber pressure-sensitive adhesives such as SBR, SIS, and SBS.

The Role of Silane Coupling Agent in Organic Adhesives

Jul / 21, 2022

The Role of Silane Coupling Agent in Organic Adhesives
Silane coupling agent is a compound that can produce certain binding force with polar and non-polar substances at the same time. It is characterized by having both polar and non-polar moieties in the molecule, such as amino silane, epoxy silane, alkyl silane and benzene. Organic functional groups such as alkali are often chemically combined with organic functional groups in the binder matrix resin; methylamino, ethylamino, etc., these genes are easily hydrolyzed into silanols, which can be combined with inorganic substances (glass, silica, metal, clay, etc.) The oxides on the surface combine and react with hydroxyl groups to form stable silicon-oxygen bonds. Therefore, by using a silane coupling agent, a "molecular bridge" can be set up between the interface of inorganic and organic matter, connecting two materials with completely different properties, thereby effectively improving the bonding strength of the interface layer. Adding a silane coupling agent to the adhesive can not only improve the adhesive strength, but also improve the durability and moisture-heat aging resistance of the adhesive. For example, polyurethane, although it has high adhesion to many materials, its durability is not ideal, and its durability is significantly improved after adding a silane coupling agent. When studying the wet-heat durability of titanium alloy adhesives, by adding a silane coupling agent to the epoxy adhesive used, the shear strength retention rate of the adhesive after wet-heat aging increased from about 80% to about 97% About. Silane coupling agents can even be used directly as adhesives for bonding silicone rubber, fluor rubber.

The Performance Index of Petroleum Resin for Hot Melt Adhesive

Jul / 08, 2022

The Performance Index of Petroleum Resin for Hot Melt Adhesive
Performance index of petroleum resin for hot melt adhesive When formulating hot-melt adhesives and pressure-sensitive adhesives, the matrix resin only has cohesive force when it is melted at a certain temperature. Once the temperature drops, the cohesion will decrease or even lose its cohesive ability.   Adding petroleum resin to the elastomer can not only improve the viscosity and wettability of the hot melt adhesive, improve the surface contact effect and characteristic bonding performance, and obtain an ideal balance between viscosity, cohesive strength and interface strength; By adjusting the rheology of the adhesive, increasing the glass transition temperature of the mixture, and adjusting the heat resistance temperature of the hot melt adhesive, the use environment of the hot melt adhesive is expanded.   As an amorphous petroleum resin polymerized from mono- and di-olefins with complex components, there is no fixed melting point, and the ring and ball softening point of the resin becomes an important factor in determining the performance of the resin. Other physical properties of petroleum resin such as chromaticity, compatibility, melt viscosity, acid value and iodine value are also important factors determining the application field of petroleum resin.   Product Recommend: »Best Adhesive Property Petroleum Hydrocarbon Resin C5 Manufacturer »Maleic Modified Rosin Ester Resin for Hotmelt Adhesives Improve Bonding Force »HC5100 Aliphatic Hydrocarbon Resin C5 for Rubber Adhesive

Why does tackifying resin increase tack? - ECOPOWER

Jun / 23, 2022

Why does tackifying resin increase tack? - ECOPOWER
Why does tackifying resin increase tack?   Tackifier resins refer to small molecular compounds that can improve the viscosity of rubber materials, especially the surface viscosity. Usually, the relative molecular mass of these small molecular substances is between several hundred and ten thousand, and they have a high glass transition temperature. According to their sources and synthetic routes, they can be mainly divided into two categories: natural products and their derivatives and synthetic resins. Tackifying resin is mainly used for polymer modification, it is widely used in adhesives, coatings, inks and as rubber compound, asphalt modifier and polyolefin modifier.   Tackifying resin is one of the indispensable materials in the production process of rubber products and tires. A comprehensive understanding of tackifying resin is conducive to the selection of different types of raw materials according to different situations in production. Generally speaking, natural series resins include rosin and terpene resins; synthetic series resins include polymer C5 petroleum hydrocarbon resins, C9 petroleum resins. As polymer modifiers, tackifying resins are rarely used alone, but in most cases as a compounding agent to increase polymer adhesion, increase initial viscosity, and reduce operating or processing viscosity.

Variation of Fumed Precipitated Silica Particles in Silicone Rubber Applications

Jun / 09, 2022

Variation of Fumed Precipitated Silica Particles in Silicone Rubber Applications
Precipitated Silica results in the structuring of the silicone rubber, mainly based on a large number of hydrogen bonds between Precipitated Silica and high molecular weight polysiloxanes.   Reinforcing fillers for silicone rubber can be divided into reinforcing fillers and non-reinforcing fillers according to the reinforcing effect. The former has a diameter of 10~50nm and a specific surface area of ​​70~400m2/g. The effect is better; the latter is usually 300~10000nm, the specific surface area is below 30m2/g, and the reinforcement effect is poor. The reinforcing filler used in silicone rubber mainly refers to synthetic Precipitated Silica, also known as Precipitated Silica. Precipitated Silica is divided into fumed Precipitated Silica and precipitated Silica.   Fumed Precipitated Silica The size, specific surface area, surface properties and structure of fumed Precipitated Silica particles are related to the ratio of raw gas, combustion rate and residence time of SiO2 core in the combustion chamber. The finer the fumed Precipitated Silica particles, the larger the specific surface area and the better the reinforcement effect, but the worse the performance. On the contrary, the particles are coarser, the specific surface area is smaller, and the enhancement effect is poor, but the operability is better. Fumed Precipitated Silica is one of the most commonly used silicone rubber reinforcing agents. The rubber compound reinforced with it has high mechanical strength and good electrical properties after vulcanization. Fumed Precipitated Silica can be used in combination with other reinforcing agents or weak reinforcing agents to prepare rubber compounds with different application requirements.   SAI800 High Anti Yellowing Silica in Silicone Rubber » Medium particle size: 10-14um and BET specific surface area 130-160 m²/g   SAI779-1 Reinforcing filler Silicone Rubber » Medium particle size: 10-14um and BET specific surface area 150-180 m²/g   SAI779 Good Processing Precipitated Silica in Silicone Rubber » Medium particle size: 10-14um and BET specific surface area 1120-160 m²/g

Silicone Industry Continues to Prosper - ECOPOWER

May / 24, 2022

Silicone Industry Continues to Prosper - ECOPOWER
In the first quarter of this year, the net profit of listed companies in the silicone field generally achieved positive growth. "The price of silica gel will continue to rise this year, mainly driven by factors such as the boost in global chemical product market demand after the impact of the new crown pneumonia epidemic, the recovery of industry demand, and the domestic 'dual control' policy. It will cause supply to closely follow demand, so the increase will not be too large." Hong Qianjin, a researcher at the Academia Sinica, said in an interview with a reporter from China Business News that the current large-scale expansion of the company's silica gel project will not cause excess production capacity. Due to the low per capita GDP of emerging market countries, there is still a large gap and growth prospects in per capita organic silicon consumption compared with developed countries. Therefore, emerging market countries have a large market demand space, which is conducive to balancing the gap between my country's organic silicon export and production capacity. Over the past two years, the focus of global manufacturing has shifted to China. Due to the strong export of terminal downstream products, new application scenarios in the market continue to expand, and demand continues to grow; in addition, silica gel is still concentrated in large and medium-sized production enterprises. At the same time, from the perspective of the international market, the imbalance between supply and demand in the global shipping market has rapidly changed from oversupply to undersupply. The import dependence of European, American and Southeast Asian countries on Chinese silicone products continues to increase. Domestic enterprises export well, prices rise, and overseas sales are more successful. The growth rate of the industry has increased significantly.
