General description:

C5/C9 copolymer resins is a new line of our products. They are produced with C5 and C9 fraction put together at a certain ratio and therefore has the advantages of both C5 and C9 resins.   

 Application:

C5/C9 copolymer resins are widely used in hot-melt adhesives, adhesives, glues and rubber and tire industry. It’s gradually taking the place of expensive C5 and is well accepted by customers.

In the rubber industry, copolymer resin can not only improve the adhesion between molecules, but also improves adhesion between rubber particles and steel radial cord and is best for products such as high-end rubber products such as radial tires.

In hot-melt adhesive, adhesive, glue industry, C5/C9 copolymer resins not only provides good initial tack, but also can be used to adjust the longevity and strength of adhesion as rosin resins
