Q1: What is the primary functional role of SK EP1065BM/NM TPE in polymer formulations?
A: SK EP1065BM/NM TPE is a thermoplastic elastomer designed to serve as a high-performance impact modifier and soft-phase component, particularly in rigid polypropylene (PP) and polyethylene (PE) systems. It enhances toughness, flexibility, and low-temperature performance without significantly compromising stiffness or processability.
Q2: Is SK EP1065BM/NM TPE suitable for food-contact applications?
A: While SK EP1065BM/NM TPE is formulated with non-toxic, FDA-compliant raw materials, final regulatory compliance depends on the complete formulation, processing conditions, and end-use requirements. Customers must conduct full migration testing and obtain certification through their own qualified laboratories for specific food-contact applications.
Q3: How does SK EP1065BM/NM TPE differ from conventional SEBS-based TPEs in terms of processing behavior?
A: SK EP1065BM/NM TPE exhibits lower melt viscosity and improved thermal stability during extrusion and injection molding compared to many standard SEBS grades. This allows for faster cycle times, reduced energy consumption, and better dispersion in PP/PE blends—especially at elevated shear rates typical in high-output production lines.
Q4: What are the recommended drying conditions prior to processing?
A: To ensure optimal mechanical properties and surface quality, it is recommended to dry SK EP1065BM/NM TPE at 70–80 °C for 2–4 hours using a desiccant dryer. Extended drying beyond this range is not required and may contribute to unnecessary thermal history.
