Ceramized Thermoplastic Polyolefin (TPO)

Liyang Tiansheng Insulating Materials Co., Ltd. supplies ceramifiable thermoplastic polyolefin (TPO) cable compound in the form of uniform white cylindrical granules, engineered as a high-performance insulation and sheathing material for low- and medium-voltage fire-resistant cables. The product is ready for direct extrusion processing and is compatible with standard cable manufacturing lines.The defining characteristic of this compound is its ceramification behavior: upon exposure to flame or extreme heat, the material undergoes a ceramic-forming reaction, producing a dense, rigid inorganic ceramic layer that preserves the cable's insulation integrity and maintains circuit continuity under fire conditions. This performance advantage makes it a superior alternative to conventional XLPE and PVC insulation materials in fire-critical applications.In terms of processability, the TPO base matrix delivers excellent melt flow consistency, dimensional stability, and smooth extrusion surface quality — supporting high-speed, continuous production with low scrap rates. The compound is fully halogen-free and low-smoke, releasing minimal toxic gases during combustion, meeting the stringent safety standards required for buildings, rail transit, and industrial environments.Typical downstream applications include fire survival power circuits, emergency lighting cables, rail and metro wiring systems, and industrial control cables. Liyang Tiansheng offers customized compound development to meet specific performance targets and client formulation requirements, providing cable manufacturers worldwide with a consistent, high-quality insulation material supply.
