Q1: What is the primary function of Sanhua PE K1041 Masterbatch?
A: Sanhua PE K1041 is a polyethylene-based masterbatch formulated to enhance processability and surface finish in PE extrusion and injection molding applications. It functions as a processing aid and slip/anti-block additive system, helping reduce melt viscosity and improve film clarity or part release.
Q2: Which polyethylene resins is this masterbatch compatible with?
A: Sanhua PE K1041 is specifically designed for use with LDPE, LLDPE, and HDPE homopolymers and copolymers. It demonstrates good dispersion and stability across a range of PE grades used in blown film, cast film, and rigid packaging applications.
Q3: How should Sanhua PE K1041 be incorporated into the production process?
A: The masterbatch is added directly to the base PE resin using standard gravimetric or volumetric feeding systems. It is typically used at low concentrations and requires thorough mixing—either via pre-blending or side-stuffer feeding—to ensure uniform distribution before extrusion or molding.
Q4: Does Sanhua PE K1041 comply with food contact regulations?
A: Sanhua PE K1041 is formulated with components commonly accepted for indirect food contact applications in polyolefin packaging. However, final regulatory compliance depends on the complete formulation, processing conditions, and end-use requirements—users are advised to conduct application-specific testing and consult applicable regional guidelines.
Q5: What storage conditions are recommended for optimal performance?
A: Store Sanhua PE K1041 in its original sealed packaging in a cool, dry environment, away from direct sunlight and sources of heat or moisture. Prolonged exposure to high humidity or elevated temperatures may affect flow properties and dispersion efficiency.
