Product Design - Thermoset Plastics

These plastics can be shaped, and reshaped using heat, as they have long monomer chains that are not interlinked.

Thermoplastics include; Urea formaldehyde, Polyester Resin, Epoxy Resins, Melamine formaldehyde.

Urea formaldehyde; electrical fittings, handles/door knobs, adhesive used in MDF.

Polyester Resin; Bonding fibers (kevlar, carbon fiber glass), casting.

Epoxy Resins; adhesives, bonding fibers.

Melamine Formaldehyde; adhesives, bonding fibers.

• Liquid in raw state.
• Good insulator.
• Brittle without reinforcement.
• Chemical resistance.

Used for adhesives and bonding fibers.

• Good insulator of heat/electricity.
• Brittle, easily snapped.
• Stiff, doesn't bend/shape.

• Electrical fittings;
• It is a good conductor of electricity, so there is no chance of the user getting an electric shock.
• It is heat resistant so will not be effected the high wattage.

• Good Heat/Chemical resistance.
• Brittle, easily snapped.

Used for adhesives and bonding fibers.

• Heat resistant.
• Very Strong.
• Hard.

Used for adhesive adhesive and bonding fibers.
