TPE charging pile cable sheath material is made of high-purity resin as the base material, with halogen-free flame retardants, antioxidants, etc. mixed and extruded into granules. It has excellent performance such as halogen-free, heat-resistant, and weather-resistant, has no precipitation pollution, meets the relevant requirements of ROHS, and is easy to extrude and process.
Product Application: Suitable for the production of outer sheath and insulation layer of charging pile cables required by GB/T 33594 standard.

Notes:
1. When the storage environment is humid or the surface quality requirements are high, the pellets can be placed in a hot air hopper at 90°C to dry for 1 to 2 hours.
2. The screw should be cleaned before extrusion to ensure the cleanliness of the product. It is recommended to use an 80-mesh or 100-mesh filter.
