Q1: What is the primary function of Sanhua PE W9050-3 masterbatch?
A: Sanhua PE W9050-3 is a polyethylene-based masterbatch formulated to enhance processability and surface finish in PE injection molding and extrusion applications. It is designed to improve melt flow stability and reduce die buildup during high-speed processing.
Q2: Which polyethylene resins is this masterbatch compatible with?
A: Sanhua PE W9050-3 is optimized for use with LDPE, LLDPE, and HDPE homopolymers and copolymers. Compatibility with specific grades should be verified through small-scale trials due to variations in resin molecular weight distribution and additive packages.
Q3: What is the typical dosage range when incorporating this masterbatch into PE compounds?
A: Dosage depends on the target performance and base resin characteristics, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight. Optimal loading should be determined experimentally to balance performance benefits and cost efficiency.
Q4: Does this masterbatch contain any regulated substances or require special handling for food-contact applications?
A: Sanhua PE W9050-3 is formulated without intentionally added heavy metals, phthalates, or BPA. However, regulatory compliance for food-contact or medical use must be confirmed separately based on final formulation, processing conditions, and applicable jurisdictional requirements.
