    NEED BUSHING WITH HIGH PV VALUE

    You should consider a polymer bushing Fluorolon 4000 (PPS) bearing or Fluorolon 3000 (PEEK). You can acheive PV over 400,000 in both lubricated. <www.aptechno.com> Good Luck.

    Need a material to use in ...

    You have given enough information that leads me to recommend and Acrylic DR or PET would be your best canidates without going into a more expensive material such as TPX. a clear material used for laboratory wear, High Temp, Chemical and UV resistant. See ou r web site: http://www.aptechno.com

    PTFE Vs. TFE

    There is no difference, however both must be sodium etched before any adhesive will bond. You can find more information on PTFE, Teflon at our website. http://www.aptechno.com

    Low friction plastic

    In pursuant to your request: we are manufacturers of engineered and advanced plastics for seals and polymers bearings. We are experts at low friction bearing applications. Since you are uesing PA66/ Glass you have a mechanical application, urethanes and Teflon, acetals will not surfice. I would...

    Vane material

    We have extensive experience in vane applications, their are a few materials we recommend, our Fluorolon PEEK being the most common, it has the mechanical strength, deminsional stabilty and does not have the hydrolitic problems of Torlon. If the application does not see moisture at elavated...

    Material for burner nozzle

    I have experience in replacing high temperature metal nozzles with plastic materials. They offer superior wear to say stainless, but the temperaure limitations are around 500 degrees F. I would suggest a bearing grade of Ryton, PEEK or Polyimide all have tensile's of 15,000 to 35,000 psi...

    PTFE Thermal Stability ?

    You anwser is that Teflon (PTFE) has a 90% declination of mechanical properties at 260 C. The modified PTFE (TFM) has a slightly better declination rate about 83 % at 260 C. The material doe not flow at elavated temperature like a typical thermoplastic, howver any load will cause cold flow or...

    I seek a more durable plastic material

    Your application poses a few problems, you need a high temperature material with superior wear resistance, yet not to hard and above all else FDA approved for food contact. You have only a few options, Teflon (PTFE) with a 10% polimide filler, this would be twice the cost of your unfilled...
