EVOH

Striving for strength, independently researching and developing the first industry leader in mainland China. Chuanwei brand ethylene vinyl alcohol copolymer resin EW series products are thermoplastic high barrier resins developed by Chuanwei Chemical's own technology. They have good high barrier properties, transparency, and formability, and are one of the ideal raw materials for packaging materials, automotive fuel tanks, and pipeline materials. It fills the gap of this kind of products in Chinese Mainland, and its oxygen barrier performance is 10000 times that of LDPE.

Main purpose:

Packaging materials: The series of products are widely used for packaging food, medicine, daily chemical products, etc. due to their excellent gas barrier properties and transparency.

Pipeline material: The series of products have excellent processing and molding properties, as well as oxygen blocking properties, and can be used for oxygen blocking underfloor heating pipes, etc., playing a role in creating comfortable living spaces.

Automotive fuel tank: The series of products have excellent oil resistance, solvent barrier properties, and other properties, making them ideal materials for the manufacturing of automotive fuel tanks and other containers.
