Langfang Bide Sealing Materials Co., Ltd.

Continuous PTFE strip for drawing-specific sealing enquiries.
Bide describes a flexible, continuous PTFE sealing tape that can be cut and arranged for a joint. The listing identifies a white PTFE material form and discusses compressibility and recovery. Buyers should agree strip width, thickness and the required joint layout, with material grade and operating limits selected for the actual flange rather than a generic tape application.
