32

What is a filler?

An additive which bulks out the polymer granules/powder. Eg: sawdust.

33

What is a flame-retardant?

An additive which makes a chemical reaction on the surface of the plastic product when it starts to combust, this stifles the combustion. Eg: used in polymer foam in seat cushions.

34

What is an anti-static agent?

An additive which reduces the effects of static charges in synthetic materials.

35

What is a plasticiser?

An additive which makes the polymer product less brittle and lowers the melting temperature.

36

What is a stabiliser?

An additive which protects the polymer against the effects of UV (sunlight) exposure, like fading and breaking down. Eg: in window and door uPVC.

37

What are biodegradable plastics?

Plastics that can break down all by themselves with warmth, dampness, contact with micro-organisms and time.

38

What is bio-batch?
