Sub-Product

HIPS consists of the Polystyrene Backbone with Polybutadiene Chains branching from it in each direction. In order to produce the Graft Polymer, Polybutadiene (Rubber) or any similar elastomeric Polymer is dissolved in Styrene and polymerized. This Reaction allows for two simultaneous Polymerizations, that of Styrene to Polystyrene and that of the Graft Polymerization of Styrene-Rubber.

HIPS is a low cost, Plastic Material that is easy to fabricate and often used for low strength structural applications when impact resistance, machinability, and low cost are required. Its major applications include machined prototypes, low-strength structural components, housings, and covers.

During commercial use, it can be prepared by Graft Copolymerization with additional Polymer to give the Product specific characteristics. The advantages of HIPS includes:

• FDA compliant
• Good impact resistance
• Excellent machinability
• Good dimensional stability
• Easy to paint and glue
• Low cost
• Excellent aesthetic qualities
