    Bonding

    All common orthotic materials can be bonded to PPT. When using Polyolefin plastics, surface roughing of the plastic, a common practice, is recommended. As always, read and understand the label directions of the cement you use, with special attention to drying time.

    If you are using non-abraded PPT, it may be helpful to rough the surface slightly with sandpaper before applying the adhesive. PPT is easily cut with scissors to produce a finished look. Thicker material, ¼” or more, can also be rough cut on a band saw.

    Chemical Resistance

    PPT is unaffected by mild inorganic acids and bases. It shows modest swelling with oils, greases, and other linear hydrocarbons. In most cases, physical properties recover to a great extent as the solvents evaporate.

    Corrosion Resistance

    Excellent (AMS 3568)

    Temperatures

    PPT tolerates temperatures up to 250º F for brief periods. Its embrittlement temperature is -60º F.
