Good Electrical and Thermal insulators
Good Strength to Weight ratio
Generally good resistance to atmospheric and chemical erosion
Low Melting point (Cost effective moulding)
Lightweight
Wide range of colours available including transparent colours
Plastics are often referred to as Polymers (Many Part)
Thermo Plastics vs. Thermosetting Plastics
Thermo Plastics -
Made from polymer chains (See right)Can be re-formed / recycled
Low forming temerature
Thermosetting Plastics-
Made from Polymer chains linked together (crosslink), (See right)
Can not be re-formed after initial setting.
Thermo Plastics (Thermo Polymers)
ABS - Acrylonitrile Butadiene Styrene : Hard wearing, Shatter resistant
CA - Cellulose Acetate : Heat resistant, Hard wearing
Nylon - Polyamide : Good wear resistance, Low friction
PMMA - PolyMethylMethAcrylate : Opaque, Cost effective
PP - PolyPropylene
HIPS - High Impact PolyStyrene : Impact Resistant
PS - PolyStyrene : Heat resistant, Lightweight, Cost effective
LDPE - Low Density PolyEthylene
uPVC - PolyVynil Chloride
PVC - (unplasticised, flexible) PolyVynil Chloride : Flexible, Hard wearing, Lightweight
PET - PolyEthylene Terephthalate : Malleable, Lightweight, Cost effective
Thermoset Plastics (Thermoset Polymers)
Epoxy Resins - Surface coatings, Encapsulation of electrical components, Adhesives
Melamine Formaldehyde - Tableware, Decorative laminates
Polyester Resins - Castings, Used in GRP (Glass Reinforced Castings)
