Applications
HD5502XA is engineered for extrusion blow molding of small to medium hollow containers. The combination of low MFR and good anti-sagging performance makes the grade well-suited to motor oil bottles and automotive fluid containers, where parison control directly affects wall thickness uniformity and the ability to meet tight volume tolerances in high-speed production.
Cosmetics and personal care packaging represents the other major application segment. Shampoo bottles, lotion dispensers, and cream jars produced in HD5502XA benefit from the resin's natural-color pellet base, which allows pigment masterbatch incorporation without interference from off-tone polymer. The 1,131% elongation at break gives thin-wall cosmetic containers resilience against cracking during assembly and transit — a recurring quality issue when converters switch to stiffer, lower-ductility grades.
Daily chemical product bottles — household cleaners, disinfectants, detergents — place the most demanding chemical resistance requirements on HDPE packaging. HD5502XA's anti-corrosion performance makes it a reliable choice for bottles in contact with surfactants, alkaline solutions, and dilute acids. The flexural modulus of 1,215 MPa ensures that filled containers maintain shape during warehousing and stacking without permanent deformation.
Why Source Through BASTONE
BASTONE Petrochem operates as a direct distribution channel for petrochemicals from China's top three producers. HD5502XA from PetroChina Dushanzi reaches BASTONE through an established supply relationship, which means allocation access tied to producer schedules rather than spot-market availability. For packaging converters running continuous blow molding lines, supply continuity is as critical as resin specification — a grade substitution mid-run causes downtime and scrap.
Every HD5502XA shipment from BASTONE carries batch-traceable COA documentation covering MFR, density, tensile properties, and pellet appearance conformance. Import authorities, brand owners, and production QC teams across export markets increasingly require this level of traceability for food-contact and cosmetic packaging supply chains. BASTONE prepares full export documentation through Zhejiang Bastone Technology Co., Ltd, including SGS test reports on request, commercial invoices aligned to declared HS codes, and packing lists formatted for customs clearance in major import markets.
BASTONE's parent group operates its own R&D center and manufacturing sites across four production bases. When buyers need support on grade selection — comparing HD5502XA against alternative blow molding grades for a new container design — the team provides technical input backed by production-side knowledge, not just a datasheet forward. Samples for mold trials are available prior to full container commitments.
