LITHIUM-ION SEPARATOR INJECTION MOLDING EXTRUSION
PVDF copolymer resin product is a copolymer of powder or particle shaped polyvinylidene fluoride. Due to the presence of comonomers, PVDF not only has good mechanical strength,chemical resistance,aging resistance and other properties,but also has good flexibility and low melting point,lt can be applied to PVDF product processing fields such as injection molding and extrusion, and can also be used for coatings such as lithium battery separators.

Application
1.DS2026-01 Mainly used for lithium battery diaphragm coating, both oil-based and water-based coatings can be used.
2.DS2026-02 Preparation of PVDF products through molding,extrusion and other processing processes.
Attention
The processing temperature should not exceed 350°C,to avoid decomposition and the generation of toxic gases.
Package, Transportation and Storage
1.Packed in plastic bags and placed in paper drums, with a net content of 20Kg per drum.
2.The product is transported according to non-dangerous product.
3.It should be stored in a clean and dry environment at 5-30℃ to prevent impurities such as dust and water vapor from mixing in.
