High Impact Polystyrene

from Wikipedia, the free encyclopedia

High Impact Polystyrene ( English , abbreviated to HIPS ) is a rubber- modified, high-impact polystyrene . The thermoplastic plastic is well established with housings, for example, computers , televisions or telephones . Inside refrigerators , the first, very cold-resistant layer often consists of HIPS. The plastic is also used in plastic toys.

Another area of ​​application for HIPS is its use in 3D printers as a washable carrier material.

HIPS has a density of around 1.04-1.08 g / cm 3 . In the polystyrene matrix, HIPS contains around 4–12 percent by mass of a polybutadiene rubber, depending on the type . Flame retardants ( DecaBDE , HBCD ) are sometimes added to the matrix to reduce flammability and combustibility.
