Plastics

There are two types of palstics and they are Thermosetting plastics and Thermoplastics.

                                                                                                                                               Polymers: summary of plastics:

Good electrical and thermal insulators
Good strength to weight ratio
Generally good resistance to atmospheric and chemical erosion
Low melting point
Lightweight
Available in a wide range of colours and transparacy

Thermoplastics:

ABS-Acrylonitrile butadiene styrene
CA-Cellulose acetate
Nylon- Nylon
PMMA-Para-Methoxymethamphetamine
PP-Polypropylene
HIPS-High impact polystyrene
PS-Polystyrene
LDPE-Low density polystyrene
HDPE-High density polystyrene
uVPC-Polyvynil chloride
PVC-unplasticized flexible, polyvynil chloride
PET-Polyethylene terephthalate
PC-Polycarbonate

Thermosetting plastics:

Epoxy resins: Surface coatings, adhesives

Melamine formaldehyde: Tableware, laminte surfaces

Polyester Resins: Castings used in GRP

Urea Formaldehyde: Electrical fittings, adhesives
