The resulting Kunlun-brand polystyrene delivers high transparency, excellent rigidity, and reliable dimensional stability. Procurement teams source the resin specifically for optical and consumer applications where clarity and low residual monomer content dictate final product quality.<\/p>\n<p>A melt flow rate of 3.0\u00b11.0 g\/10min provides a balanced viscosity profile suitable for both injection molding and sheet extrusion. The Vicat softening point of \u226596\u00b0C ensures molded parts maintain structural integrity under moderate thermal loads. Factory specifications strictly limit residual styrene monomer to under 300 ppm, meeting stringent safety and odor requirements for consumer goods manufacturing.<\/p>\n<p>Optical performance defines the value of the 300NT grade. The yellow index ranges from -8 to -4, guaranteeing a blue-tinted, crystal-clear base material that resists discoloration. Zero color particles per kilogram means manufacturers avoid cosmetic defects and high rejection rates in transparent components.<\/p>\n<p>BASTONE Petrochem distributes authentic PetroChina Dushanzi materials directly from domestic refinery allocations. Buyers receive full Certificate of Analysis (COA) documentation with every container. Direct supply chain access eliminates spot-market inconsistencies, protects downstream production schedules, and guarantees material authenticity.<\/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\">GPPS 300NT \u2014 \u044d\u0442\u043e \u043f\u043e\u043b\u0438\u0441\u0442\u0438\u0440\u043e\u043b \u043e\u0431\u0449\u0435\u0433\u043e \u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043d\u0438\u044f, \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0438\u043c\u044b\u0439 \u043a\u043e\u043c\u043f\u0430\u043d\u0438\u0435\u0439 PetroChina Dushanzi \u043f\u043e\u0434 \u0431\u0440\u0435\u043d\u0434\u043e\u043c Kunlun. \u041e\u0431\u043b\u0430\u0434\u0430\u044f \u043f\u043e\u043a\u0430\u0437\u0430\u0442\u0435\u043b\u0435\u043c \u0442\u0435\u043a\u0443\u0447\u0435\u0441\u0442\u0438 \u0440\u0430\u0441\u043f\u043b\u0430\u0432\u0430 3,0 \u0433\/10 \u043c\u0438\u043d \u0438 \u0438\u0441\u043a\u043b\u044e\u0447\u0438\u0442\u0435\u043b\u044c\u043d\u043e\u0439 \u043e\u043f\u0442\u0438\u0447\u0435\u0441\u043a\u043e\u0439 \u043f\u0440\u043e\u0437\u0440\u0430\u0447\u043d\u043e\u0441\u0442\u044c\u044e, \u044d\u0442\u043e\u0442 \u043c\u0430\u0442\u0435\u0440\u0438\u0430\u043b \u0432 \u043e\u0441\u043d\u043e\u0432\u043d\u043e\u043c \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u0435\u0442\u0441\u044f \u0432 \u0441\u0432\u0435\u0442\u043e\u0440\u0430\u0441\u0441\u0435\u0438\u0432\u0430\u044e\u0449\u0438\u0445 \u043f\u043b\u0430\u0441\u0442\u0438\u043d\u0430\u0445 \u0438 \u043f\u0440\u043e\u0437\u0440\u0430\u0447\u043d\u044b\u0445 \u043b\u0438\u0442\u044c\u0435\u0432\u044b\u0445 \u043a\u043e\u043c\u043f\u043e\u043d\u0435\u043d\u0442\u0430\u0445.<\/p>\n<p data-path-to-node=\"1\" data-imt-p=\"1\">BASTONE Petrochem \u043f\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u0435\u0442 \u044d\u0442\u043e\u0442 \u043f\u043e\u043b\u0438\u0441\u0442\u0438\u0440\u043e\u043b \u043d\u0430\u043f\u0440\u044f\u043c\u0443\u044e \u0441 \u0437\u0430\u0432\u043e\u0434\u043e\u0432, \u0441 \u0432\u043e\u0437\u043c\u043e\u0436\u043d\u043e\u0441\u0442\u044c\u044e \u043e\u0442\u0441\u043b\u0435\u0436\u0438\u0432\u0430\u043d\u0438\u044f \u043f\u0430\u0440\u0442\u0438\u0439, \u043d\u0430 \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0441\u0442\u0432\u0435\u043d\u043d\u044b\u0435 \u043f\u0440\u0435\u0434\u043f\u0440\u0438\u044f\u0442\u0438\u044f \u043f\u043e \u0432\u0441\u0435\u043c\u0443 \u043c\u0438\u0440\u0443.<\/p>\n<p>PP Virgin Granule: PP Modified Granule \u2192 PP Virgin Granule: PP Modified Granule<\/p>","protected":false},"featured_media":807,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[57],"product_tag":[],"class_list":["post-819","product","type-product","status-publish","has-post-thumbnail","product_cat-gpps","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>GPPS 300NT | PetroChina Kunlun \u2013 BASTONE<\/title>\n<meta name=\"description\" content=\"PetroChina Kunlun GPPS 300NT.
