The High Impact Polystyrene Engineering Polymer is used by automobile industries, electrical companies, shoe industries, PVC cables and Pipes Industries.
Specifications of High Impact Polystyrene Engineering Polymer are:
- Injection Moulding: A melt temperature of 180-280 C is recommended. Generally, mould temperature should lie between 30 and 50 C. For thin wall objects moulded at short cycle times it could be useful to cool down the mould down to 10 C. Mould shrinkage lies between 0.4 and 0.7% depending on the grade used.
- Extrusion: Grade with a high viscosity is suitable for extrusion. A melt temperature of 180-220 C is generally used.
- ABS has a broad processing window and can be processed on most standard machinery. Pre-drying is not always needed for injection moulding with a vented cylinder but if drying is needed then 4 hours at 80 C is generally sufficient. Signs of moisture are stripes, streaks or bubbles in the moulding and if any of these are seen then the material should be pre – dried.
