Product Description
This product is a powdered polyvinylidene fluoride copolymer. Due to the presence of comonomers, PVDF has good mechanical strength, chemical resistance, and aging resistance, as well as good flexibility and a lower melting point. It can be used in the field of water treatment membranes and lithium-ion battery separators.
Application
It is mainly used as a membrane material for water treatment.
Packaging
- Packed in plastic bags, then into paper drums or cartons, each drum has a net weight of 20kg, and each carton has a net weight of 40kg.
Transportation, Storage & Precaution
Transportation: Transport as non-dangerous goods. Avoid heat, moisture, or severe vibration during transportation.
Storage: Store in a clean, dry environment at 5~30℃ to prevent dust, moisture and other impurities from getting in.
Precaution: Avoid processing or using at temperatures above 350℃ to prevent decomposition and the generation of toxic gases.
