D/W 300 is a family of polyimide film products with no adhesive. D/W 300 materials combine excellent physical, electrical and mechanical properties at temperatures ranging from -452F (-269C) to 752F (400C). D/W 300 materials offer excellent dimensional stability along with very good chemical resistance. Applications for D/W 300 polyimide films range from electrical and thermal insulation to use in transformers, heat sealing devices and more.
