HIPS is milky white opaque beads, with high impact strength and toughness, can be colored arbitrarily, molding processability, chemical corrosion resistance, electrical properties are also good, modified polystyrene by rubber, although the impact strength and toughness are very good Great improvement, but the tensile strength, bending, hardness, light resistance and thermal stability are lower than homopolymer. Impact-resistant polystyrene contains rubber components, and its impact strength is 5-10 times higher than that of GPPS, which expands the application range of polystyrene and has partially replaced expensive ABS materials.
HIPS is a modified material of PS, which contains 5-15% rubber in its molecule. Its toughness is about four times higher than that of PS, and its impact strength is greatly improved. It has flame-retardant, stress-cracking resistance, high gloss, and extremely High impact strength grade, glass fiber reinforced grade and low residual volatilization grade. Other important properties of standard HIPS: bending strength 13.8-55.1MPa; tensile strength 13.8-41.4MPa; elongation at break 15-75%; density 1.035-1.04 g/ml; it has PS with molding processing and strong tinting strength The advantages. HIPS products are opaque. HIPS has low water absorption and does not require pre-drying during processing.
Because the HIPS molecule contains 5-15% rubber, which affects its fluidity to a certain extent, the injection pressure and molding temperature should be higher. Its cooling rate is slower than that of PS, so it needs sufficient holding pressure, holding time and cooling room. The molding cycle will be slightly longer than that of PS, and its processing temperature is generally 190-240℃. HIPS resin absorbs water slowly, so it does not need to be dried under normal circumstances. Sometimes too much moisture on the surface of the material will be absorbed, thereby affecting the appearance of the final product. Drying at 160°F for 2-3 hours will remove excess water. There is a special white edge problem in HIPS parts, which can be improved by increasing the mold temperature and clamping force, reducing the holding pressure and time, etc. The water trapping in the product will be more obvious.
