Applications
K9928H was developed for thick-wall injection-molded components where long flow paths and demanding service conditions must be met in a single base resin. Washing machine inner drums are a primary outlet: the geometry demands consistent wall formation across deep cylindrical sections, and the high MFR of 28.8 g/10min ensures complete fill without requiring elevated injection pressures that could induce residual stress and warpage. The low-warpage performance documented in the product specification is directly relevant here — inner drum assemblies must hold dimensional tolerances that allow proper bearing alignment and drum clearance throughout the appliance's service life.
Home appliance housings for large white goods represent a natural extension of the same property set. Large outer panels and structural casings are warpage-sensitive: shrinkage variation across thick walls produces parts that miss assembly tolerances or require secondary correction. The flexural modulus of 1.32 GPa gives enough in-part rigidity to allow wall geometry optimization without sacrificing structural performance, while the high flow rate supports the cavity fill consistency that large-tool injection requires.
Automotive modified compounds consume K9928H as a base resin for bumper fascias, door trim substrates, and interior structural panels. Compounders blending ICP PP with rubber, talc, or glass fiber use this grade because the high MFR provides processing latitude across different compound formulations, and the inherent ICP toughness reduces the elastomer loading needed to meet cold-impact targets. The −20°C impact strength of 63.5 J/m gives formulators headroom before compounding begins.
Why Source K9928H Through BASTONE
BASTONE Petrochem maintains active distribution relationships with China's top-3 petrochemical producers — SINOPEC, PetroChina, and CNOOC — through its export platform, Zhejiang Bastone Technology Co., Ltd. K9928H originates from the Dushanzi Petrochemical complex in Xinjiang, one of PetroChina's primary polymer production sites, and BASTONE's sourcing pipeline into Dushanzi gives buyers allocated supply access rather than dependence on spot availability.
Documentation quality reflects the parent company's manufacturing background. BASTONE's group operates 4 production sites and an R&D center, which means the export team understands what technically complete supply documentation looks like. Every K9928H shipment includes property testing against Q/SY DS112-2017, test method citations, and batch traceability — not a reformatted template with generic values.
BASTONE's diversified product range across polyolefins, organic chemicals, fuel additives, and drilling chemicals means buyers who need K9928H alongside other material categories can consolidate orders through a single export relationship. Sample quantities are available before committing to full container volume, and the team handles flexible trade terms, container consolidation, and pre-shipment coordination as part of standard export service.
