INTRODUCTION
Engineering plastics are tough plastics that can withstand high loads or stresses. They can be machined and remain dimensionally stable. They are typically used in the construction of machine parts and automobile components. Important examples of this class of plastics include Poly ethylene(high density)poly ethylene(low density) poly propylene poly styrene poly ether ether ketone poly methyl methacrylate poly acetals, poly phenylene sulphide poly vinyl chloride phenolic formaldehyde melamine formaldehyde urea formaldehyde epoxy resins poly urethane, unsaturated polyester silicones
The structure of their giant chains makes these plastics highly resistant to shock, and gives them a characteristic toughness.
Plastics are almost always electrically insulating, and for this reason they have found use as essential components of electrical and electronic equipment (including implants in the human body).
