Product Description:
POLYCIMA-80MP85V is a high flame-retardant thermoplastic elastomer based on a composite of SEBS and PPO, incorporating an efficient flame-retardant system primarily composed of phosphorus-nitrogen flame retardants. This material exhibits excellent mechanical and physical properties, electrical performance, and processability, while complying with environmental regulations such as ROHS, SVHC, 16P, and PAHS.
Product Applications:
Suitable for USB data cables, electronic wires, drag chain cables, SFP high-speed transmission wires, and other products. It passes the VW-1 flame retardancy rating test as specified in UL758, supports various extrusion methods such as pressure extrusion, semi-pressure extrusion, and tube extrusion, and certain specifications can also be produced using injection molding processes.

Key Processing Precautions:
A: It is recommended to dry at 90°C for 2–4 hours.
B: Before and after processing this material, it is recommended to clean the screw or die with polypropylene (PP) or polyethylene (PE).
C: Scrap material can be reused. It must be dried before use. The addition amount should generally not exceed 15%, and the properties remain largely unaffected.
