Polymer Enhancement Flashcards

1
Q

Lubricants

A

Reduces the viscosity of the molten polymer, making it less sticky and allowing more intricate shapes to be formed. Lubricants also allow the moulding temperature to be lowered saving energy.

Q

Plasticisers

A

Allow plastics to become less hard and brittle at normal temperature use. They can also also help in processing because they allow polymers to be easily formed at higher temperatures.

Q

Fillers

A

Sawdust and wood flower provide bulk to the product meaning that less polymer is required.

Q

Biodegradable plasticisers

A

Please make the polymer more flexible softer and easier to breakdown which means faster degradation time

Q

Antioxidants

A

Reduce the mental deterioration of the polymer from exposure to oxygen in the air.

Also help prevent increased brittleness surface cracks and pigment discolouration

Q

Uv stabilisers

A

Prevent the polymer chains being broken down by sunlight. UV attack causes colour loss and brittleness.
