HIPS is actually a modification of PS, the material contains 5% to 15% rubber content, so compared to PS material, HIPS is higher in toughness, about four times as much as PS, impact strength is also stronger. PS has the characteristics of moulding and processing, high colouring power, etc., HIPS also has.

And ABS is propionitrile-butadiene-styrene terpolymer, belongs to the amorphous polymer, is also a general-purpose engineering plastics, with a variety of diversity. Mechanical strength and toughness, rigidity, firmness are better, more widely used.

HIPS market prospects are huge, in the home appliance industry in the refrigerator liner, HIPS added more and more common, added with HIPS material refrigerator liner, has a high viscosity, low chromaticity, low gel content, etc., to meet the consumer on the refrigerator liner impact resistance, low-temperature cracking, as well as the appearance of the various aspects of the requirements.

HIPS can also be used as a special material for anti-rattling, air conditioning work due to thermal expansion and contraction and friction of plastic parts, may produce rattling, which needs to be added to the air-conditioning damping, thereby reducing the noise, if the cost of using ABS materials increase is relatively large, so some manufacturers will choose HIPS materials. Through experiments found that the HIPS anti-alarm ringing lower human ear.
