General Properties & Characteristics
of Plastic Families

Plastic
Characteristics / Properties

ABS
(Acrylonitrile-butadiene-styrene)

Rigid, low-cost thermoplastic, easily machined and thermo-formed.
Acetal
Engineering thermoplastic with good strength, wear resistance, and dimensional stability. More dimensionally stable than nylon under wet and humid conditions.
Acrylic
Clear, transparent, strong, break-resistant thermoplastic with excellent chemical resistance and weatherability.
CPVC
(Chlorinated PVC)
Thermoplastic with properties similar to PVC, but operated to a 40-60°F higher temperature.
Fiberglass
Thermosetting composite with high strength-to-weight ratio, excellent dielectric properties and unaffected by corrosion.
Nylon
Thermoplastic with excellent impact resistance, ideal for wear applications such as bearings and gears; Self-lubricating under some circumstances
PEEK
(Poly-ether-ether-ketone)
Engineering thermoplastic, excellent temperature resistance, suitable for continuous use above 500°F, excellent flexural and tensile properties.
PET
(Poly-ethylene-terephthalate)
Dimensionally stable thermoplastic with superior machining characteristics compared to acetal.
Phenolic
Thermosetting family of plastics with minimal thermal expansion, high compressive strength, excellent wear and abrasion resistance and a low coefficient of friction. Used for bearing applications and molded parts.
Polycarbonate
Transparent, tough thermoplastic with high impact strength, excellent chemical resistance and electrical properties, and good dimensional stability.
Polypropylene
Good chemical resistance combined with low moisture absorption and excellent electrical properties. Retains strength up to 250°F.
Polysulfone
Durable thermoplastic, good electrical properties, operates at temperatures in excess of 300°F.
Polyurethane
Thermoplastic, excellent impact and abrasion resistance, resists sunlight and weathering.
PTFE
(Poly-tetra-fluoro-ethylene)
Thermoplastic with a low coefficient of friction, withstands heat up to 500°F, inert to chemicals and solvents, self-lubricating with a low thermal expansion rate.
PVC
(Poly-vinyl-chloride)
Thermoplastic, resists corrosive solutions and gases both acid and alkaline, good stiffness.
PVDF
(Poly-vinyl-idene-fluoride)
Thermoplastic, outstanding chemical resistance, excellent substitute for PVC or polypropylene. Good mechanical strength and dielectric properties.
