PTFE unsintered tape is made of virgin PTFE resin. It has expanded network structure consisting of superfine fibers and joints. It has good flexibility, high longitudinal strength and easy deformability in the transverse direction. PTFE unsintered tape is ideal material for packing and threadsealing applications.But it can’t be used in occasion of contacting with high oxygen or liquid gas.
Applications
PTFE unsintered tape is mainly used for packing and threadsealing
