Styrene: Relatively brittle, inexpensive
and rigid. The best application is for very small transparent boxes where
little abuse is anticipated.
Polyethylene: Especially high density,
offers a good combination of qualities for most handling purposes. It is
highly resistant to moisture, oil, most solvents and acids. Is extremely
tough, light-weight and economical. Because of its low-friction surface,
it is usually unsuitable for use on conveyors, especially where there are
inclines. Its propensity to hold a static charge may tend to attract dust.
Low creep resistance and low dimensional stability may limit use for very
heavy loads. Translucency and tooling marks may create objectionable appearance.
Polypropylene: Similar to polyethylene,
does not have the surface toughness to resist abrasion. High temperature
and solvent resistance make it the choice in many situations.
ABS (Acrylonitrile-Butadiene-Styrene):
Material used for telephones, is tough, relatively rigid and offers good
acid and solvent resistance. Appearance and dimensional stability are good.
Easily fabricated. An engineering thermoplastic, it is somewhat more expensive
than others mentioned above.
STATIC CONTROL MATERIALS
Virtually all PCC products are now available in conductive or static
dissipative materials. Please see "Static Control Products" section
for applications and specifications.
