1、Bottle Grade Chips |
|
Characters: odor-free, non-toxic, high transparency, high strength and air-tightness, light weight and easy transportability, uniform size, stable viscosity, excellent processing ability and high product yield. In particular, the products fully conform to international standards for food-grade usages due to their low heavy metal, acetaldehyde and ash contents. These products are ideal 'green' materials for beverage bottle and food packaging.

2、Industral Grade Chips |
|
Used: The Industrial Grade Chips produced by DSR are mainly used for producing spinning polyester Industrial Yarn, film and sheet. It provides both regular type (high strength and low elasticity series) and High-Modulus-Low-Shrinkage (HMLS). The Industrial Grade Chips have the typical characteristics of high spinability, strong breaking strength, high elasticity modulus, low extensibility and good impact strength. Industrial grade fibres can be used for tire cord, seat belt and etc.
