Q1: What is the primary function of Sanhua PE K1020 masterbatch?
A: Sanhua PE K1020 is a polyethylene-based masterbatch designed to enhance processability and surface finish in PE extrusion and injection molding applications. It typically functions as a processing aid and slip/anti-block additive, helping to reduce melt viscosity and improve film or part release from tooling.
Q2: Is this masterbatch compatible with all types of polyethylene resins?
A: Sanhua PE K1020 is formulated for optimal compatibility with LDPE, LLDPE, and HDPE homopolymers and copolymers. Performance may vary with highly filled or specialty PE formulations—compatibility testing under actual processing conditions is recommended before full-scale use.
Q3: What is the typical dosage range for Sanhua PE K1020 in PE compounds?
A: Dosage depends on the base resin, processing method, and desired performance effect, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight. Start with 0.5–1.0% and adjust based on functional evaluation and end-use requirements.
Q4: Does Sanhua PE K1020 meet food contact compliance requirements?
A: Sanhua PE K1020 is intended for industrial and packaging applications where regulatory compliance is required. While its components are selected from substances commonly accepted in food-contact polymers, formal food contact approval must be verified per regional regulations and specific end-use conditions. Customers should conduct appropriate migration testing and consult local regulatory guidance.
