Automotive Low-Voltage Wiring Harness/Signal Cable Material Solutions

Special Features

TPE-S series
are polymer materials modified from SEBS polystyrene-based substrates with flame retardants and other additives. They possess excellent heat resistance, ozone resistance, migration resistance, good flexibility, scratch resistance, and electrical properties.

Modified PP type
Dielectric constant 2.10~2.30, loss factor <10 (test frequency: 1MHz), excellent and mature insulation and anti-attenuation performance. Applications include insulation of FLR Ethernet (sensor) link cables for German standard automotive wiring harnesses, etc.
