HIE-1 is manufactured through bulk polymerization using styrene as the primary feedstock, with a controlled addition of low cis-polybutadiene rubber. The rubber phase is dispersed throughout the polystyrene matrix during polymerization, then the product passes through devolatilization and pelletizing stages. The result is a natural-colored cylindrical or flat-round pellet with zero colored granule contamination per kilogram \u2014 a meaningful quality indicator for processors running clean, unpigmented lines or supplying food-contact packaging.<\/p>\n

The 3.3 g\/10min melt flow rate, measured at 5.0 kg load per ISO 1133, places HIE-1 in the mid-viscosity range for HIPS grades. Processors working with thinner thermoform gauges will find this flow rate manageable without excessive sag during heating cycles. The Vicat softening point of 88\u00b0C, measured per ISO 306, gives downstream product designers a reliable upper-use temperature ceiling for ambient and refrigerated applications.<\/p>\n

A Charpy impact strength of 12 kJ\/m\u00b2 (ISO 179) and tensile strength of 27 MPa (ISO 527) reflect the characteristic HIPS performance profile: not brittle like general-purpose polystyrene, but not as stiff either. The polybutadiene rubber phase absorbs impact energy, which is why HIE-1 handles drops and mechanical stress in applications like refrigerator compartment liners and appliance housings without cracking. Buyers specifying thin-wall parts with mechanical assembly requirements will find these values relevant at the design stage.<\/p>\n

Residual styrene monomer content at 180 ppm (10\u207b\u2076 wt, ISO 2561) and a yellow index of 11 (ASTM E-308-1) both sit within ranges acceptable for many packaging end uses. Buyers targeting food-contact applications should verify grade-specific regulatory compliance against the relevant authority \u2014 EU 10\/2011, FDA 21 CFR, or GB 9685 for the Chinese domestic market \u2014 before specifying HIE-1 for direct-contact layers.<\/p>\n

BASTONE distributes HIE-1 sourced directly from Dushanzi Petrochemical Company, with full certificate of analysis documentation traceable to the production batch. Each COA references the test methods cited above, allowing procurement teams to verify incoming goods against the published datasheet without relying on third-party lab testing as a first step.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
