PP/PE/PP Three-Layer Co-Extrusion film
Scope of Application: High-performance lithium-ion battery (consumer electronics, electric tools, high-performance polymer battery)
Product Specifications:9um/14um/16um/20um/25um
Product Features:
It can achieve ultra-thin production;
High toughness and superior resistance to falling;
It has a "thermal shutdown function" with high security;
Compared with the foreign three-layer composite film, the advantages of thermal shrinkage are obvious;
It combines the advantages of dry and wet films, and has advantages over wet coating
The DSC data shows that the PE melting temperature of the three-layer co-extrusion PP/PE/PP film is quite different from the PP melting temperature. When the internal temperature of the lithium battery exceeds 120 °C, the PE layer begins to close, but the PP layer still has a supporting effect and the film will not break until 165 °C. The difference between the heat-closed hole temperature and the heat-melting temperature is as high as 45 °C, which is equivalent to adding a protective layer on the PE film, truly realizing the "thermal shutdown function" and "double closed-hole insurance", with better safety performance.
