Plastics
Thermoplastics
High Impact Polystyrene
Versatile
Easy to machine
Low cost
Good aesthetics
Polyethylene (PE)
Most common plastic
Different properties depending on density
Polyethylene Terephthalate
Cheap to produce, Strong and impact resistant
Rigid or semi rigid
Can hold liquid, gasses and alcohol
Poly-Vinyl Chloride (PVC)
Very commonly used
Can be rigid or flexible
High hardness, good insulator
Polypropylene (PP)
Extremely Veristile
Lowest density of all thermoplastics
Chemical resistance
Cheap
ABS
Low cost
Good resistance to impact
Rigid, easy to machine
Heat resistant
Thermo setting Plastics
Urea-Formaldehyde
High tensile strenght
High heat distortion temperature
Low water absorption
High surface hardness
Melamine Resin
Good electrical insulator
Very low thermal conductivity
Hard and scratch resistant
Stain resistant
Polyurethane
Good electrical insulator
High compressive and strengt
Can be flexible and elastic
Epoxy Resin
Tough
Chemically resistant
Rigid and tough
Electrical insulator
Temperature resistant
Can be used in conjunction with metal
