PLASTICS ADDITIVES – FOAMING/BLOWING AGENTS
There may be occasions when it is desirable to reduce the weight of a thick sectioned injection moulding. Alternatively, it might be necessary to reduce the warping of a moulding or eliminate the sink marks, caused by ribs and bosses on a conventional or thin walled moulding.
In certain circumstances gas assisted moulding can be used but where this is not possible or is not economically viable, foaming or blowing agents can provide an alternative solution. The result of using these chemical additives is a foam structure to the material.
