Exceptional Mechanical Strength & Impact Resistance
The high molecular weight structure of S-1300 significantly enhances tensile strength, elongation at break, and impact resistance
Optimized Melt Flow & Processing Stability
Designed for extrusion and calendering, S-1300 exhibits balanced melt viscosity and high melt strength, minimizing die swell and ensuring uniform thickness in films, sheets
Superior Plasticizer Retention & Flexibility Compatibility
With plasticizer absorption ≥28 g/100g, S-1300 efficiently binds phthalates and non-phthalate plasticizers, delivering consistent softness and flexibility in PVC films, artificial leather, and wire insulation without blooming or migration.
Flexible Compounds: Cable and wire insulation, PVC soft films, synthetic leather, shoe soles, and flexible hoses
Calendered Products: Transparent and colored sheets, flooring, wall coverings, and packaging films
· S-1300 is manufactured under ISO 9001 and GB/T 5761-2006 standards, with batch-to-batch consistency verified by in-line rheology and particle analysis
· All batches comply with REACH, RoHS, and FDA indirect food contact regulations for global market access
· Full technical documentation, including SDS, COA, and customs compliance certificates, provided upon request
· Stable supply chain supported by domestic petrochemical bases ensures reliable bulk delivery worldwide
Packaging: 25kg moisture-proof woven polypropylene bag with inner PE liner; custom packaging (e.g., bulk bags, palletized) available
Storage: Store in a cool, dry, well-ventilated warehouse. Keep away from direct sunlight, heat sources, and moisture. Do not store with acids, alkalis, or oxidizing agents
