Product Description

Product description:
GDY-2 is a kind of vinylidene fluoride homopolymer with high melt mass flow rate and high melt viscosity, which belongs to thermoplastic fluororesin. The resin is resistant to most chemical media, and has excellent heat resistance, high mechanical strength, high wear resistance, ultraviolet resistance and radiation resistance. GDY-2 can be used as resin for fluorine-containing powder coatings.

The vinylidene fluoride homopolymer began to decompose slightly above 300ºC, and hydrogen fluoride gas was produced.

Precautions:
1. GDY-2 is packed and sealed in double polyethylene plastic bags and packed in hard paper drums. The net content per barrel is 20kg. Can also be packaged according to user requirements.
2. GDY-2 should be stored in a clean and dry warehouse.
3. Severe vibration and moisture should be avoided during transportation.
4. This product should avoid processing and use above 370ºC to prevent decomposition to produce toxic gas.
