Ptfe Injection Molding
PTFE stands for polytetrafluoroethylene, also called teflon, which is known as the King of Plastic in polyethylene injection molding because of its corrosion resistance. It is the mostly used fluoroplastic currently and it takes up 60% of the total demand. PTFE (teflon) compression molding process has been one of the best and easiest choices to produce PTFE plastic products. With excellent properties, PTFE molds are extensively used in medical, electrical and mechanical fields for manufacturing PTFE parts.
Features and Applications for PTFE:
- Low friction. It can be used for plain bearings, gears, ski bindings, etc and more applications which requires high performance of anti-friction.
- Dielectric. With its high radio frequencies, it is widely used in connector wires and cables for aerospace and computer and in printed circuit boards used at microwave frequencies.
- High resistivity. It is an suitable material for fabricating long-life electrets, the electrostatic analogues of permanent magnets.
- High corrosion resistance. It makes PTFE popular in laboratory environment, such as container for acid or other corrosive chemicals.
- Non-reactivity and high heat resistance. PTFE is often used as the liner in hose assemblies, expansion joints, and in industrial pipe lines (most popular one: teflon pipes), where it needs to be inert to maintain what it is. For its high temperature rating, it is commonly used in coating non-stick frying pans and other cookware.
- PTFE Molded Products & Applications:Bushings, Gears, Holders, Guides, Seals, Strainer, Lined & Jacketed Dip Pies, Nozzle Liners, Tubes, Plain Bearings, Gears, Slide Plates, Seals, Gaskets, Bushings etc.(in Aerospace, computer, electrostatic, aerospace industry)
