Liyang Tiansheng Insulating Materials Co., Ltd. manufactures ceramifiable silicone rubber insulated fire-resistant cables, utilizing advanced ceramifiable silicone rubber as the primary insulation and inner sheath material. These cables are engineered for low- and medium-voltage fire-resistant wiring systems, serving applications where reliable circuit integrity under fire conditions is critical — including commercial buildings, industrial facilities, tunnels, and infrastructure projects.
The defining feature of this product is its ceramification technology: when exposed to high temperatures or direct flame, the silicone rubber insulation undergoes a ceramic-forming reaction, rapidly solidifying into a hard, dense ceramic shell. This ceramic layer effectively blocks flame propagation and maintains electrical insulation integrity, ensuring uninterrupted power supply to fire suppression, emergency lighting, and safety systems during a fire event.
Beyond its fire performance, ceramifiable silicone rubber retains excellent flexibility under normal operating conditions, with a working temperature range of -60°C to +180°C. It offers strong resistance to oils, coolants, and chemical exposure, making installation straightforward even in complex routing environments. The material is fully halogen-free and low-smoke, minimizing toxic gas emissions during combustion to protect both personnel and equipment.
Liyang Tiansheng offers full customization across conductor configurations — from single-core to multi-core designs (up to 4-core × 185mm² and beyond), with options for shielded constructions and varied jacket colors — serving cable manufacturers and engineering procurement teams across domestic and international markets.
Liyang Tiansheng Insulating Materials Co., Ltd. was founded in 2013. It is a professional service provider dedicated to application solutions for flame‑retardant and fire‑resistant insulation materials, as well as thermal runaway solutions.
Boasting a strong technical team and more than 40 professional employees, Liyang Tiansheng produces technically mature products at an advanced industry level. The company serves the top ten cable manufacturers in China, including Jiangsu Shangshang, New Far East, and Hengtong Group.
Liyang Tiansheng focuses on promoting new‑type fire‑resistant silicone materials and silicone applications for aerospace, nuclear power, new energy vehicles, and related components. Its core business covers various special silicone rubber products for cable manufacturers. After years of steady development, the company now has an annual production capacity of 5,000 tons of various special silicone rubber and fire‑resistant insulation products, with annual sales exceeding 50 million yuan.
The company mainly uses high‑quality imported raw materials and specialized products from listed companies as its key production materials. Production processes are managed in accordance with the IATF 16949 new energy management system. Supported by extensive practical experience, a rigorous working attitude, and a complete testing system, the company ensures the quality of its products and services. Its professional and technical capabilities remain at the leading level among domestic counterparts.
