NylonAll grades of Nylon have toughness and resiliency in addition to high fatigue
strength. Resistance to oils and hydrocarbon solvents is very Acetal ( DELRIN ) displays good impact resistance, dimensional stability with
outstanding surface hardness due to its high degree of crystaline structure.
Acetal has high dielectric strength and is resistant to many solvents while
exhibiting negligible water absorption. Typical applications include roller
bearings, gears, reels, counters, control cams, valves, and pump parts. Polycarbonate ( LEXAN ) displays the highest impact strength over a range of
temperatures from -60°F to 270°F. It is appropriate for all Polypropylene has high impact resistance and structural rigidity. It is
unaffected by most solvents at room temperature. PP has excellent insulating
properties and is extremely lightweight. Its high fatigue strength makes it an
ideal under cyclic loading conditions. ULTEM ( Polyetherimide) keeps hardness and mechanical properties from
-40 °F to 356 °F. It is radiation-resistant, microwave transparent with natural
flame retardant qualities. Reinforced grades have even higher mechanical
strength. With its unequaled qualities, ULTEM is the ideal
replacement for steel and many metals making it perfect for a wide range of
electronic and medical applications. ABS has excellent impact strength and resistance. Used extensively in
appliances, automotive and computer components. ABS plastics may be painted or
plated. Polyethylene is unique because of its flexibility at low temperatures,
excellent electrical resistance, and low dielectric constant. PE's self
lubricating properties also make it ideal for applications such as rollers,
skids and other uses which call for a non-stick, low friction material.
Polyethylene is available in a wide range of densities including Ultra High
Modular Weight for gears, driven, impellers, cams, etc. Teflon ( Polytetrafluoroethylene ) has an extremely low coefficient of
friction which makes it the ideal choice where surface wear might be a
problem. Teflon also exhibits a useful service life from below -100°F to 500°F.
Its resistance to solvents is excellent throughout a wide range of temperatures.
Teflon's low dielectric constant and electrical resistance also remain constant
throughout this range of temperature. Teflon is a registered trademark of DuPont. PVC ( Polyvinylchloride ) properties include chemical inertness, resistance
to water and weather, high strength-to-weight ratio, tough dent resistance with
electrical and thermal insulative properties. PVC has continuous resistance to
heat from120°-160°F. Isoplast (Glass-filled Polyurethane ) has excellent chemical, solvent and
abrasion resistance. Isoplast has a high notchecl impact KYNAR® UHMW UHMW (Ultra High Molecular Weight Polyethylene) has a unique combination of properties: extremely low coefficient of friction (See Table 1) which promotes free flow high abrasion resistance to low stress abrasion high chemical/corrosion resistance nil moisture absorption, in fact, water repellent outstanding impact resistance against blunt objects lightweight/easy to install ease of fabrication and machining using normal woodworking tools operating temperatures from -200'C to 65 to 80'C (upper limit depending on mechanical stress) non stick. CP7-D CP7-D Polypropylene has good chemical resistance to alkalines and
peroxide with limited acid resistance. This material can be used in wet bench
and wafer tool fabrication to avoid fire-suppression system installation &
maintenance costs. |
