Structured Blue PTFE
Suit to variety of aggressive fluids,particularly suitable for use with stress sensitive and/or frange joints.
DP1570 is a structured PTFE-Gasket-Sheet manufactured by a unique process which provides a high level of fiberillation to overcome the creep relaxtion and cold flow problems associated with normal (skived or moulded) PTFE sheets.
DP1570 is produced from virgin PTFE resin filled with hollow glass micro sphere.
