Q1: What is the primary functional role of SK EP1380BM/NM TPE in polymer formulations?
A: SK EP1380BM/NM TPE functions as a high-performance thermoplastic elastomer modifier, primarily used to enhance flexibility, impact resistance, and melt processability in rigid thermoplastic matrices such as PP, PS, or ABS—without compromising thermal stability during standard extrusion or injection molding.
Q2: Is SK EP1380BM/NM TPE suitable for food-contact applications?
A: While SK EP1380BM/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 regulatory validation for their specific application and jurisdiction.
Q3: How does SK EP1380BM/NM TPE differ from conventional SEBS- or TPU-based TPEs?
A: Unlike many SEBS grades, SK EP1380BM/NM TPE offers improved compatibility with polyolefins and reduced surface tackiness. Compared to TPU, it provides better hydrolytic stability and lower moisture sensitivity—making it particularly suited for humid environments or long-term outdoor applications where dimensional consistency is critical.
Q4: What are the recommended drying and processing conditions?
A: SK EP1380BM/NM TPE typically requires low-temperature drying—generally at 60–70 °C for 2–4 hours—prior to processing. Melt processing is stable within a range of 160–210 °C, depending on equipment type and residence time; extended exposure above 220 °C should be avoided to maintain optimal mechanical retention.
