The PRS®-A2020 is a liquid aromatic hydrocarbon modified C5 petroleum resin which is produced by our company with applying self-developed and advanced technology. It is manufactured through such process as C5 refining and catalyzed polymerization by utilizing automatically continous producing technology. The product is a high-quality transparent liquid organic polymer, which possesses a narrow distribution of molecular weight and superior initial adhesivity. It is especially designed as a tackifier to have outstanding compatibility with elastomers such as natural rubber, butadiene rubber, lbutyl rubber, PE rubber, styrene inlayed section copolymer(SIS, SBS) and EVA. Not only does it possess better adhesive effect but also improve the mechnical and optical performances of the entire tackifier system in industries of pressure sensitive adhesives, hot melt adhesives and tyre. The product has very good heat stability, light color, low odor and low volatileness. It is neither dangerous nor poisonous and it has no corrosivity or radioactivity. The product can be seen as an equivalent of Exxonmobil's Escorez 2520. Samples of the products are available now, all clients are welcome to request samples to test.
