Mould Information:
plastic material | advantage | disadvantage | industry example |
PS(Polystyrene) | Clear plastic, very moldable, inexpensive, recyclable, high
chemical resistance, high electrical resistance, heat distortion
~200°F | Cracks and breaks easily | Disposable cups, disposable applications, decorative applications,
electrical applications |
HIPS (High Impact Polystyrene) | Very moldable, relatively inexpensive | Very moldable, relatively inexpensive | Picture frames, shower walls, food containers |
ABS (Acrylonitrile Butadiene Styrene) | Engineered plastic that can be customized to desired levels of
stiffness, hardness, heat deflection, and many other
characteristics | UV sensitive – requires a UV protective cap layer for extended
exposure | UV sensitive – requires a UV protective cap layer for extended
exposure |
PVC (PolyvinylChloride) | Very high chemical resistance, stain resistant, stiffer than ABS,
high room temp. impact strength, natural flame retardant qualities | Difficult to process | shower surrounds, moldings, kick panels, display cases |
Polycarbonate | Extremely high impact resistance, high clarity – good for
transparent parts, precision molding, good insulator, high heat
distortion point ~270°F | Low chemical resistance to certain substances (oil, gasoline, harsh
chemicals), can be difficult to process, higher material and
processing cost | Visors, plastic guards, transportation components (headlights,
taillights, instrument panels), appliance drawers, skylights |
Polycarbonate/ABS | When compared to true polycarbonate – less expensive, lower heat
distortion ~240°F, much easier to process, higher chemical
resistance | When compared to true polycarbonate – reduced clarity, lower heat
distortion ~240°F | When compared to true polycarbonate – reduced clarity, lower heat
distortion ~240°F |
PETG (polyethylene- terephthalate) | Very easy to process, high clarity – good for transparent parts | Not UV stable – unsuitable for extended exposure | Structural automotive parts, hand tools, industrial components |
