We are specializing in manufacturing the series of pollyimide films for 20 years. It is an enterprise with a longer-production history and a large scale in the insulation material field in China. Our main products include 6051 polyimide film and HF, FHF (polyimide fluorine-46) film. They have many excellent properties except that we can offer the most competitive price.1. good properties of insulation and tensile strength;2. good temperature � resistance and used in wide temperature range, between -60℃~+250℃ for a long period and between �269℃~+400℃ for a short period without changing in tensile strength or insulating property.3. good chemical stability and resistance to corrosion.4. excellent flame retardant property5. good radio-resistance. After the film being irradiated with r ray of 109 remain its properties unchanged.6. can be complexed with many materials, when complexed with fluorine resi
