Hydrogenated petroleum resin Generally C5 or C9 petroleum resin is reddish-brown to light yellow, and can become white or transparent after hydrogenation. In the application of hot melt adhesives and adhesive tapes, the transparency of the resin is very important. Hydrogenation can also improve adhesion, weather resistance, stability and compatibility. C5 hydrogenated petroleum resin is made from the C5 resin fraction cracked by ethylene as raw material, and is obtained by cationic polymerization of diene and monoene in the C5 resin component. C9 Hydrogenated Petroleum Resin is a low molecular weight semi-hydrogenated water-white thermoplastic resin derived from chemical raw materials. In view of good heat resistance, good compatibility with EVA, SBC and other polymers, it also has good thermal stability and very low odor. DCPD hydrogenated petroleum resin is mainly composed of dicyclopentadiene and other low-molecular-weight polymers generated by polymerization under certain temperature and pressure conditions through a special process.

As an inorganic non-metallic material, glass fiber has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is often used as a reinforcing material in composite materials, electrical insulation material and thermal insulation material. However, the surface of glass fiber is very polar, and it is difficult to be compatible with non-polar resin, which greatly reduces its filling effect.

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.  

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?   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.
