PTFE Rod Through A Certain Pressure

Yangzhong Tianyou Seals Co.,Ltd | Updated: Aug 03, 2017

PTFE Rod Through a certain pressure

PTFE rods are mixed with PTFE and additives, into the mold in the compaction, and then through a certain pressure, the mold maintained at a certain temperature, after a period of time, the powder compacted together after the formation of polytetrafluoroethylene Of the embryo, the embryo material taken out, placed in the sintering furnace heated to the melting point, so that PTFE particles melt into a whole, after cooling made of semi-finished or finished products. Is an uncoated polytetrafluoroethylene resin (which may contain recycled polytetrafluoroethylene resin, which is suitable for processing various gaskets, seals and lubricating materials working in corrosive media and electrically insulating parts used at various frequencies, Fluoroethylene resin) by molding, paste extrusion or plunger extrusion process.

PTFE rods have three molding processes

Diameter of 1-4mm rods using polytetrafluoroethylene dispersion resin by paste paste extrusion, conventional roll-like packaging; diameter of 3-160mm pole selection of PTFE resin suspension by plunger made; diameter 6mm The rods up to 400mm in diameter can be molded into short rods. Short rods can also add different fillers according to different properties to enhance their performance, such as molybdenum disulfide, polystyrene, carbon fiber, graphite, copper powder, color Powder and so on.

In the known plastic polytetrafluoroethylene has the best resistance to chemical corrosion and dielectric properties, non-aging, non-stick, in the case of no load can be used at -190 ℃ + 260 ℃ temperature, in the known solid material It has a low coefficient of friction.

Main technical indicators: (Note: when the rod diameter is greater than 16mm, only test the apparent density) Project name Apparent density Tensile strength ≥ Fracture elongation ≥ Unit g / m? Mpa% Indicators 2.1 ~ 2.3014.0140 Product use:

Diameter of 1-4mm bar used for electroplating hanging basket, mold factory, Zhu Bao plant mold pumping and so on.

Diameter of 3mm above the bar can be processed into a variety of frequencies used in the electrical insulation parts, a variety of corrosive media in the sealing gasket, anti-sticking materials, lubricating materials.

PTFE rod characteristics

The use of a wide temperature range (from -200 degrees to +260 degrees Celsius).

Basically all chemicals are corrosive except for some fluoride and alkaline metal fluids.

Excellent mechanical properties include anti-aging properties especially for bending and swing applications.

Outstanding flame retardancy (in accordance with ASTM - D635 and D470 test steps) is classified as flame retardant in air.
