HIPS is a blend of GPPS with butadiene rubber. HIPS sheet is known for its ease of thermoforming ability, processing, good dimensional stability, impact strength and rigidity. It has resistance for many chemicals like alkali, salts, lower alcohols, and many acids.  Normal limiting factors for HIPS are heat resistance, oxygen permeability, light (UV) stability and resistance to oily chemicals. 

   Applications:
HIPS has a high dielectric strength and is widely used for:

• Ship, Automobile and Aerospace applications
• Laminated electronic circuits
• High frequency insulation sheeting
• Insulators, and other electrical applications
• Inner bodies of refrigerators etc.
