High impact polystyrene (HIPS), as ecru opaque particles.With high impact strength and toughness.Can be any color, molding processability, resistance to chemical corrosion, electric performance is very good also. HIPS: can injection or extrusion shaped into a variety of products, injection temperature is 160-180 degrees, the pressure of 70 mpa.
Application
HIPS
The material can be used as packaging filler, pressed into board, molded into products, or delivered on sheets or rolls. Its characteristic dimensional stability permits it to be employed in low strength construction, and in its natural translucent form makes it suitable for food processing applications.
