Product Description:
POLYCIMA-80E85V is a highly flame-retardant thermoplastic elastomer based on SEBS, formulated with a phosphorus-nitrogen flame retardant system. It offers excellent mechanical properties, electrical performance, and processing adaptability, while complying with environmental regulations such as ROHS, SVHC, 16P, and PAHS.
Product Applications:
Suitable for USB data cables, coaxial cables, drag chain cables, SFP high-speed transmission cables, and charging pile cables, among other wire and cable products. This material can pass the VW-1 flame rating test as required by UL758. Processing methods include extrusion, semi-tube extrusion, and tube extrusion; some specifications are also suitable for injection molding.

Processing Main Considerations:
A: It is recommended to dry at 90°C for 2–4 hours.
B: It is recommended to clean the screw or die with polypropylene or polyethylene before and after processing this material.
C: Scrap material can be reused. It must be dried before use, and the addition amount generally should not exceed 15%, with basically no impact on performance.
