Glass Filled Polystyrenes - Processing Versus Properties.

Abstract

The effects of injection moulding on two types of glass filled polystyrene have been considered using an instrumented moulding machine. Certain machine parameters have been shown to be important in determining the properties of specimens cut from long glass polystyrene moulded discs but rather less important with short glass polystyrene. The importance of avoiding cut edges on moulded samples has been confirmed. No obvious correlations have been found between moulding pressures and mechanical properties but a relationship exists between cavity pressure and moulding weight and size. (Author)
