HL Glossy black polyimide film is homogenous opaque film, with glossiness achieving data 115 or so, own good mechanical, chemical, thermal performance.
High temperature tape, label,battery, coverlay
Available thickness: 25um 50um
After completion of formula,the materials begin to polycondensation,flowing into resin storage,casted by casting machine,scrolling into imine furnace for complete drying,tension and imidization,and beginning to wind. After winding, start to strimming side or slitted as clients' demanding. Then the coil must be during corona treated and post-processed for good performance.
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.
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.
