Petroleum Hydrocarbon Resin C5

Petroleum Hydrocarbon Resin C5

Product Name

Styrene Modified C5 Petroleum Hydrocarbon Resin, C5 Petroleum Hydrocarbon Resin, C5 Resin, Hydrocarbon Resin C5，Aliphatic Hydrocarbon Resin

Chemical Properties

C5 petroleum resin is a type of thermoplastic resin produced through the polymerization of C5 fraction derived from the distillation of crude oil. It is widely used in various industries as a versatile and cost-effective material.

C5 petroleum resin has a low molecular weight and good solubility in organic solvents, which makes it an excellent adhesive and coating material. It is also used as a tackifier in hot melt adhesives and rubber compounds. Hydrocarbon Resin C5 can improve the hardness, gloss, and color of coatings, as well as enhance the adhesion and cohesion of adhesives.

Hydrocarbon Resin C5 Application

Applications of C5 Petroleum Resin

C5 petroleum resin, as a key tackifying resin, is indispensable in multiple industrial sectors due to its excellent tackiness, compatibility, and stability. Its primary applications can be summarized into the following three areas:

1. Adhesive Industry: Core Tackifying Component

This is the largest and most critical application area for C5 petroleum resin, where it significantly enhances the initial tack, peel strength, and cohesive strength of adhesives.

• 1.1 Hot-Melt Adhesives

  • Applications: Carton sealing, bookbinding, disposable hygiene products (diapers, sanitary napkins), woodworking/furniture, labels, etc.

  • Function: As one of the core components in the formulation, it works synergistically with base polymers such as EVA and SBS to provide effective initial adhesion and final bond strength.

• 1.2 Pressure-Sensitive Adhesives

  • Applications: Transparent tape, self-adhesive labels, protective films, medical tape, etc.

  • Function: Imparts permanent tack to the adhesive mass in combination with elastomers like SBS and SIS, enabling instant adhesion upon contact.

2. Rubber Product Industry: Processing Aid and Tackifier

In rubber processing, C5 petroleum resin serves as a processing aid and tackifier.

• 2.1 Tire Manufacturing

  • Function: Enhances the tackiness of rubber compounds, ensuring strong adhesion between tire components (e.g., tread, carcass layers) during the building process, while also improving the processability and flow of the compound.

• 2.2 Rubber Goods

  • Applications: Rubber soles, conveyor belts, sealing strips, etc.

  • Function: Increases the hardness and modulus of the rubber compound, improves mixing processing, and provides a certain reinforcing effect.

3. Coatings and Paints Industry

• Road Marking Paint

  • Function: This is a traditional and important application of C5 petroleum resin. It is added to thermoplastic road marking paints to provide hardness and wear resistance, and it bonds well with glass beads, ensuring durable reflectivity.
