Dushanzi Petrochemical&#8217;s 130,000-tonne-per-year polystyrene line runs continuously, delivering the batch-to-batch consistency that thermoforming operations require when running high-speed sheet extrusion or inline forming cycles.<\/p>\n<p>The MFR range of 3.9\u20135.7 g\/10min, measured at 5.00 kg load per ISO 1133, positions HIEM for applications that need enough flow to fill complex thermoformed geometries or injection-molded cavities cleanly, without the excessive flash that comes with higher-MFR grades. Buyers running sheet extrusion followed by vacuum forming will find this flow window practical for both thin-wall packaging and medium-weight structural components.<\/p>\n<p>Charpy impact strength at \u22657.0 kJ\/m\u00b2 (ISO 179:2000) is the property that separates HIPS from crystal polystyrene. The rubber phase dispersed through the matrix absorbs energy at impact points \u2014 the mechanism that prevents cracking when food containers get dropped, trays get stacked, or refrigerator liners take handling impacts through repeated door cycles. Applications where visual clarity is secondary to toughness are where HIPS grades like HIEM earn their specification.<\/p>\n<p>Vicat softening point at \u226580\u00b0C (ISO 306:2004) covers ambient-temperature and refrigerated-environment end uses comfortably. Cold-drink cup lids, food service containers, and indoor appliance housings all operate well within this thermal ceiling. The yellow index range of 10\u201319 (ASTM E-308-1) reflects the natural tint inherent to rubber-modified polystyrene \u2014 acceptable for pigmented, printed, or coated applications where base resin color does not need to meet optical transparency standards.<\/p>\n<p>BASTONE sources HIEM through its PetroChina distribution channel and supplies full COA documentation traceable to the originating Dushanzi production batch. Procurement teams receive the same quality records that plant incoming inspection managers need to close out material qualification files.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p data-path-to-node=\"1\" data-imt-p=\"1\">HIEM es una resina de poliestireno de alto impacto (HIPS) producida por la Compa\u00f1\u00eda Petroqu\u00edmica Dushanzi, una subsidiaria de PetroChina, mediante polimerizaci\u00f3n continua en masa a partir de una planta dedicada de poliestireno con capacidad de 130,000 toneladas por a\u00f1o.<\/p>\n<p data-path-to-node=\"1\" data-imt-p=\"1\">Con un \u00edndice de fluidez de 3.9\u20135.7 g\/10 min y una resistencia al impacto Charpy de \u22657.0 kJ\/m\u00b2, HIEM se utiliza en aplicaciones de termoformado, envasado de alimentos, envasado m\u00e9dico, componentes de refrigeradores y carcasas de electr\u00f3nica de consumo.
