C9 Hydrocarbon Resin - High-Quality Thermoplastic from China Suppliers and Factory, CAS 64742-16-1

C9 resin can be combined with other resins to replace all or part of high-priced resins, thereby reducing costs and improving the gloss, hardness, water resistance, stability and chemical resistance of products. For example, in the formula of phenolic varnish, C9 petroleum resin is used to replace rosin-modified phenolic resin and rosin calcium ester in equal amounts. The obtained product still meets the standards of phenolic varnish and phenolic enamel. However, the cost of C9 petroleum resin is less than 1/4 of that of rosin-modified phenolic resin, so it can greatly reduce costs. Adding alicyclic petroleum resin to epoxy resin and polyurethane blended paint can improve the hardness, flexure test, warm water resistance, weather resistance and other indicators of the product.

C9 petroleum resin is mainly used as a rubber softening additive. Styrene butadiene rubber is lacks of viscosity and hard. The addition of C9 petroleum resin divides the molecular chain of styrene butadiene rubber, making the product have better viscosity and softness. On the other hand, C9 petroleum resin can reduce the quantity of natural rubber in synthetic rubber, significantly reducing the cost without changing the quality of rubber products. In terms of technology, the use of petroleum resin can save a raw rubber refining process, shorten the production cycle, and improve economic benefits.
