PP J-320 SB

High-performance PP grade with balanced stiffness, impact resistance, and heat stability for industrial and household applications

PP J-320 SB is a high-performance impact copolymer polypropylene (PP) developed by Lotte Chemical Indonesia. Engineered for demanding industrial and consumer applications, this material delivers an optimal balance of mechanical strength, thermal resistance, and durability. With a tensile yield strength of 290 kgf/cm² and elongation at break exceeding 100%, it offers excellent toughness and resistance to deformation under stress. Its high flexural modulus (12,000 kgf/cm²) ensures structural rigidity, while the Izod impact strength of 11.0 kgf·cm/cm at -10°C confirms superior low-temperature resilience. The material maintains dimensional stability up to 105°C (HDT @ 4.6 kgf/cm²), making it ideal for heat-exposed environments. Additionally, PP J-320 SB meets UL94 HB flammability standards, enhancing safety in electrical and household products. Widely used in automotive parts, industrial components, storage containers, and durable consumer goods, this grade combines reliability, processability, and cost-efficiency for manufacturers seeking consistent, high-quality performance.
