Q1: What is the primary function of Sanhua PE K1048 masterbatch?
A: Sanhua PE K1048 is a polyethylene-based masterbatch formulated to enhance processability and improve surface finish in PE extrusion and injection molding applications. It is commonly used to reduce melt viscosity, minimize die build-up, and support stable production runs.
Q2: Which PE resin types is this masterbatch compatible with?
A: Sanhua PE K1048 is designed for use with a broad range of polyethylene resins, including LDPE, LLDPE, and HDPE. Compatibility may vary depending on resin density, melt index, and thermal history—preliminary compatibility testing is recommended for critical applications.
Q3: What is the typical dosage range for optimal performance?
A: The recommended dosage generally ranges from 0.1% to 2% by weight relative to the base polymer, depending on processing conditions, equipment type, and desired effect. Lower dosages are often sufficient for general flow improvement, while higher levels may be explored for demanding high-speed or thin-wall applications.
Q4: Is Sanhua PE K1048 suitable for food-contact applications?
A: This masterbatch is not pre-certified for food-contact use. Customers intending to use it in food packaging or related applications must conduct full regulatory evaluation—including migration testing and compliance verification—according to applicable regional requirements and end-product specifications.
Q5: How should Sanhua PE K1048 be stored and handled to maintain stability?
A: Store in original sealed packaging at temperatures below 30 °C and relative humidity below 60%, away from direct sunlight and sources of heat. Avoid prolonged exposure to ambient moisture prior to use, and ensure thorough drying if the material shows signs of agglomeration or handling inconsistency.
