Detailed Product Description: | PTFE Rod is a suitable processing of various gaskets, seals and lubricant work in corrosive media and an electrically insulating part at various frequencies used, etc. No addition of polytetrafluoroethylene resin filled (may contain renewable PTFE resin) by molding, extrusion paste extrusion molding or plunger rod. A very wide temperature range (from -200 degrees Celsius to +260 degrees). Basically all chemical substances with the exception of some anti-corrosive metal fluoride and alkaline liquid. Excellent mechanical properties, including anti-aging, especially for application of bending and swinging. Outstanding flame retardant (in accordance with ASTM-D635 and D470 test procedure in the air to be regulated as a flame retardant material. Excellent insulating properties (regardless of its frequency and temperature how) to very low water absorption polytetrafluoroethylene PTFE gasket sets, and has a unique set of performance self-lubricating and non-adhesive and other difficult to stick PTFE reason, there are several reasons: First tetrafluoroethylene plate PTFE gasket, low surface energy PTFE gasket PTFE molded panels, the critical surface tension is generally only 31 to 34 dynes / cm due to the low surface energy, contact angle is large, the adhesive can not be sufficiently wet PTFE, and thus can not well adhere to the PTFE;. Second, the large degree of crystallinity, chemical stability , PTFE swelling and dissolution will be more difficult than the non-crystalline polymer, when the adhesive coated PTFE surface, difficult to place into a chain polymer molecular chain domain interdiffusion and tangles, can not form a strong adhesion; third , PTFE structure is highly symmetrical, also belong to the non-polar polymers. The adhesive is adsorbed on the surface of PTFE PTFE gasket by van der Waals forces (intermolecular forces) caused by van der Waals forces comprising orienting force, dispersion force and induction force. For non-polar polymer surface, do not have the ability to induce the formation of the orientation of force and conditions, and can only form a weak dispersion forces, and thus poor adhesion properties. PTFE molded plate PTFE gasket PTFE gasket _ Guang'an _ Tianjin Tianjin Three by Three Plastic Co., Ltd. Tianjin Three plastic (www.tjzssj.com) strong, credible, in Tianjin plastic plate (sheet, section), rods, etc. accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Tianjin three and you work into the brilliant, for a better future! |
