HJ0286 [Strippable] Thermoplastic Shielding Compound for Sioplas Method

Thermoplastic strippable insulation shielding material is a non-cross-linked thermoplastic semi-conductive composite material developed specifically for silane cross-linked overhead cables (Sioplas method). This material is used for the shielding structure outside the insulation layer. While ensuring stable electrical performance, it also has good processing performance and strippable characteristics. It is especially suitable for overhead cable systems using warm water cross-linking.
Strippable design
Maintaining appropriate adhesion with the insulation layer, it is convenient for mechanical stripping during construction without damaging the insulation body, improving the efficiency of later installation and maintenance, and is particularly suitable for branch joints, terminal processing and other operation scenarios.
It has excellent thermal stability under high temperature extrusion conditions, greatly reducing common problems such as carbonization, scorching, and die accumulation, improving production efficiency and reducing downtime risks.
