Why it matters
This objective helps connect Enhancement of materials to exam-style questions, flashcards, and revision notes for Enhancement of materials.
Quick student answer
Which additive is commonly used to enhance the UV resistance of polymers?
Direct answer
UV stabilisers are additives that help protect polymers from degradation caused by ultraviolet light exposure.
Key terms
- UV stabilisers: Additives that protect polymers from UV radiation, extending their lifespan.
- Bio-batch materials: Additives that enhance the biodegradability of plastics, promoting environmental sustainability.
Common trap
Confusing UV stabilisers with other additives: Remember that UV stabilisers specifically protect against UV light, while other additives serve different purposes.
