Manufacture of Plastics

Compression Moulding

Extrusion Moulding

Extrusion Blow Moulding

Degradation of Plastic

• UV Degradation – Unless UV Stabilised– UV Radiation breaks chemical polymer bond– Evaporates– Becomes Thinner– Will Fail

Degradation of Plastic

• UV Degradation Avoidance– Use UV Stabilised Products• Added during manufacture

– Paint with External UV Protected Acrylic Paints• Solar Guard• Weathersheild

– Avoid Solvent based Paints

Degradation of Plastic

• Constant Exposure to high Temperatures

• Break Polymer Chains

• Stabilizers will make plastic resistant to heat
