SINOPEC Baling YH800 Virgin PA6 (Nylon 6) Resin — Medium Viscosity Molding Grade
Product Overview：
YH800 is a medium-viscosity virgin polyamide 6 (PA6 / Nylon 6) resin produced by SINOPEC Baling Petrochemical (Yuehua Brand) in Yueyang, Hunan — one of China’s largest and most established caprolactam-to-nylon integrated production bases, and a long-standing benchmark PA6 supplier for domestic and export markets. This natural-color grade features relative viscosity 2.85±0.03, low extractables (<0.5%) and moisture <0.07% , combining good flowability with balanced mechanical performance (tensile 60.7 MPa, flexural modulus 2087 MPa). It is designed for general injection molding, flame-retardant compounding base resin, and monofilament/brown-fiber spinning. LEMA supplies genuine SINOPEC Baling YH800 in original 25kg bags with full TDS/COA.
Key Features：
Medium viscosity, versatile — RV 2.85±0.03, suitable for both injection molding and monofilament spinning Balanced mechanics — tensile 60.7 MPa, flexural strength 86.6 MPa, flexural modulus 2087 MPa Good toughness — notched Izod 20.1 kJ/m² (dry as molded), typical PA6 wear & chemical resistance Low monomer & moisture — extractables <0.5%, moisture <0.07%, fewer bubbles/silver marks Natural milky-white color — uniform pellets, grade-1 whiteness, excellent base for dyeing or FR/GF modification Cost-effective — China’s flagship volume PA6 grade, stable supply and consistent batch quality
