Fillers
Used to reduce the bulk of the plastic, and some can increase strength and hardness of the polymer by removing brittleness. They are generally cheaper than plastics, therefore help reduce the cost. Eg. sawdust, wood flour, crushed quartz & limestone.

Flame-retardents
Reduce risk of combustion. They create a chemical reaction once combustion has begun; release agents to stifle combustion. Eg the foam used to fill seating cushions.
2 of 5
Anti-static agents
Reduce the effect of static charges that could build up on a product. Eg, walking on a carpet made from synthetic material.
3 of 5
Plasticiser
Added to improve the flow properties of plastics when being moulded. They also, reduce the softening temperature and some make the material less brittle.
4 of 5
Stabilisers
Reduce the effect of ultraviolet light; make the plastics more resistant to sunlight. Important from a structural and aesthetic point of view. Used in products exposed to the sun a lot, eg windows and doors.
