Silicone Cables vs Plastic Cables : The Fire Protection Battle
Fire Resistance cables are specific cables used in high-rise buildings, which are highly populated and critical areas such as: hotels, offices, hospitals, schools, recreational buildings, underground, tunnels, and industrial plants… Those cables can help keep fire alarms, emergency exit lights and other life-saving electrical alarm systems operating during emergency situations by giving people more time to exit a building or a transportation system.
Silicone rubber is a material to insulate cables that must conduct electricity under extreme conditions such as fire.
Our silicone rubber cables improve safety and security.
High fire resistance and improved ashes cohesion: our silicone grades are specifically formulated to maintain circuit integrity in case of fire.
Non-toxicity of residual gas: the silicone is halogen free and does not contain any toxic elements such as bromine, iodine, chlorine or fluorine.
Our silicone cables increase product life
Good mechanical property: flexibility, resistance to choc and high tear strength.
Resistance to environment: outstanding resistance to natural aging agent (UV radiation, Ozone, salted fog…), water repellency, and pollution.
Thermal stability: from -50 °C up to 200 °C
Our silicone rubber cables can reach high productivity and improved competitiveness
Several extrusion processes exist to manufacture silicone-insulated cables. Our products are suitable for the following applications: steam cure, hot air vulcanizing, salt bath cure and radiation cure.
Our silicone solutions meet the stringent standards’ requirements
Cables must comply with stringent standards, we strictly comply with European standards such as:
the European standard for circuit integrity EN 50200 PH90-PH120,
the British Standard BS 6387 C, W and Z that not only test the burning behavior of the cable but applies mechanical chocs and/or water
the German standard DIN 4102-12 that not only tests the fire performances of the cable but of the entire system
the French equivalent of the European circuit integrity standard: the NFC 32070 CR1
Located in Shanghai, Dingzun Cable are committed to your success. As cables designs can be complex and technical requirements vary a lot from one project to another, we are dedicated to provide customers with our tailored solutions. Finally, with detailed knowledge of the evolution of standards and considerable expertise in cable design, our specialists can guide you in terms of legislation as well as offering you regulatory support for your most demanding applications.
