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
