PTFE Dichtring

PTFE sealing ringadd filler,keep the basic features of PTFE, improve the stability of size under the high temperature and load. the linear expansion coefficient is lower, it improve the bear of cold flow, friction, compressive strength, hardness. However tensile strength, impact strength, elongation, Insulation, corrosion, not sticky will be lower. PTFE Fillers: fiberglass, carbon, Graphite, MoS2, Sand, Tal, Ceramaic power, Metal powder, Metal Oxide. All sizes will be produced according to customers requirement Packing: by wooden cases
