Description
EP548R is a polypropylene impact copolymer grade engineered to provide a balanced combination of stiffness, impact resistance, good flow, and stable injection-molding performance.
Its nominal melt mass-flow rate of 30 g/10 min supports efficient mold filling and the production of molded components with consistent mechanical properties and surface quality.
Food-contact and regulatory suitability should be confirmed through the latest supplier documentation for the intended market and end-use application.
Key Features
Processing Recommendations
EP548R can be processed using standard injection-molding equipment. The following processing conditions are provided as general reference values and may require adjustment according to the machine, mold design, wall thickness, and part geometry.
Actual shrinkage may vary depending on part thickness, molding conditions, gate design, and mold geometry.
Packaging
EP548R is typically supplied in 25 kg FFS bags. Final packaging availability and palletization requirements should be confirmed when placing an order.
Storage
Store the product in a dry, clean, and well-ventilated environment at temperatures below 50°C. Protect the material from direct sunlight, ultraviolet radiation, moisture, and heat sources.
Improper storage may cause material degradation, unusual odor, discoloration, or changes in the product’s physical and processing properties.
