HIPS Description
1.Scientific name: high impact polystyrene
2.English name:high impact polystyrene
3.Natural color:Natural color is a sub-white opaque material with a matt surface, flexibility, and non-brittleness; it is non-toxic and odorless.
4.Combustion properties: It is flammable and can continue to burn after the fire has been extinguished. The flame's upper end is golden yellow. When burned, it will soften and foam, emit thick smoke black columns with fly ash, and emit no liquid dripping.
5.Advantages: Because polystyrene is hard and brittle, easily broken, and not impact resistant, the rubber modification method is used to solve the problems listed above.
The most significant advantage of HIPS is its high impact strength, which is more than four times that of ABS.
Excellent electrical insulation, HIPS is simple to color and print.
HIPS has a relatively high surface hardness.
6.Disadvantages: Although HIPS has a high impact strength, its elongation rate is lower than that of ABS. As a result, self-tapping screws can easily break the screw holes designed on the shell. The gloss of the surface becomes dull due to the addition of rubber components, and the surface is dull; HIPS has poor thermal stability and low heat resistance.
Use in the manufacture of housings for household appliances.
For the manufacture of everyday necessities and toy shells
Extruded blow-molded containers, hollow articles, and bottles
Infusion forming execution The general softening mark of HIPS is around 170℃, and the decay temperature is 260℃; the customizable scope of infusion temperature is moderately huge. While infusion forming, the general use temperature is 180°C- - 240°C; in light of the presence of elastic parts, it retains a limited quantity of water. During creation, it should be persuaded to dry, and can be dried at 80-90°C for 1-2hrs; HIPS is because of elastic parts.
Consequently, the dissolve consistency of HIPS ought not be halted in that frame of mind during infusion forming, and the liquefy thickness is higher than that of PS, however the entryway and sprinter are general and can likewise be loaded up with the item; the item is inclined to electricity produced via friction, and the surface is not difficult to assimilate dust. Shrinkage rate is 5‰; flood esteem is 0.05mm
