Matte black polyimide film is homogenous opaque film, with good tensile, elongation, insulation property, widely used in solar cell,battery, tag, tape etc..
High temperature resistance
Heat resistant tag
Black high temperature resistant adhesive tape
Available thickness: 25um 50um
Packaging marking, storage and transportation
1. packing in rolls with plastic package outside, then put into carton.
2. Carton will be marked with product name, specification, quantity information
3. film should be stored in a dry and clean room.
4. during storage and transportation, dampness and mechanical damage should be avoided.
Inspectionof pi film
Thickness test: each roll take 50cm long sample doing thickness test every centimeter along transverse direction. During manufacturing, timing doing thickness test on production line.
Choose one roll each batch doing following test: tensile strength, elongation rate, voltage, shrinkage rate.
Physical properties of polyimide films
