LDPE 1L60A
Sinopec / ExxonMobil / PetroChina
This category represents premium high-flow injection molding LDPE resins, prominently featuring grades like Tianjin Petrochemical 1L60A, Sinopec Yangzi 1L60A, Zhongyuan 2750, and ExxonMobil 6201. Engineered with an exceptional melt index range of 45-55 g/10min, these materials are tailor-made for ultra-fast filling of ultra-thin walls (<0.3mm) at high speeds. They deliver an outstanding 30-40% cycle time reduction compared to standard MFI 20 grades, maintaining a robust weld line strength exceeding 80% and minimized warpage via specialized isotropic shrinkage profiles.
