Flame Retardant Rubber Sheet Black Fire Resistant Sealing Strip

Fire resistance rubber sheet is a kind of rubber sheet which can inhibit the flame burning speed or extinguish the flame directly under the ignition state. According to UL94 fire resistance standard, it can be divided into three grade: grade V0, grade V1, grade V2 .
Generally Size: Width 0.1m-2m, thickness 1mm-10mm, length according to your request
1) Non-toxic, flame retardant, electrical insulation properties
2) Flexible, kink resistance to deformation
3) Good resistance to fire, oil, acid & alkali, ozone, abrasion and heat.
4) Strong crack resistance; resistant to high and cold temperature
5) Superior electrical performance
6) Various sizes, colors, durometer could be available

Used for equipment sealing projects, industrial and mining enterprises, pipeline sealing, and factory warehouse floor laying.
It can be used as machine gaskets, automotive seals, surface laying, cushioning gaskets, gaskets, industrial water pipe seals, oil pipe seals, etc.

I. Core Characteristics

1. Exceptional Flame Retardancy
   • High – Grade Flame Retardant Performance: Flame retardant rubbers can meet UL94 V – 0, V – 1 standards or conform to GB/T 2408 requirements by incorporating various flame retardants such as halogen – based, phosphorus – based, and metal hydroxide compounds. This enables them to self – extinguish or significantly delay combustion once removed from the flame source.
   • Low – Smoke Emission: Halogen – free formulations, like those containing aluminum hydroxide or magnesium hydroxide, generate less toxic smoke during combustion. This not only improves safety but also ensures compliance with strict environmental regulations such as EU RoHS and REACH.
   • Superior Thermal Stability: These rubbers maintain their flame – retardant properties even at high temperatures. For instance, silicone rubber can withstand temperatures ranging from 200 – 300°C, while fluororubber can operate in the 200 – 300°C range. They are highly resistant to thermal decomposition, reducing the risk of ignition under extreme heat conditions.
2. Outstanding Physical and Mechanical Properties
   • Elasticity and Flexibility Retention: Flame retardant rubbers retain the inherent elasticity of regular rubbers, making them suitable for applications that require dynamic sealing or cushioning. Examples include automotive seals and shock pads, where their flexibility ensures a proper fit and long – term performance.
   • Enhanced Strength and Durability: Through the addition of fillers such as carbon black and silica, along with optimized vulcanization systems, these rubbers exhibit increased tensile strength, improved tear resistance, and enhanced abrasion resistance. This makes them durable for use in demanding industrial applications.
3. Robust Environmental and Chemical Resistance
   • Chemical Resistance: Fluororubber and neoprene – based flame retardant rubbers are highly resistant to oils, acids, alkalis, and a wide range of solvents. This property makes them ideal for use in corrosive environments, such as those found in chemical plants and the petroleum industry.
   • Aging Resistance: Silicone rubber and chlorosulfonated polyethylene rubber (CSM) demonstrate excellent resistance to ozone and UV aging. This characteristic allows them to be used in long – term outdoor applications, like building seal strips, without significant degradation over time.
4. Flexible Processing Adaptability
   • Moldability: Flame Retarded rubbers can be shaped into various forms through vulcanization processes, which can be either thermal or room – temperature vulcanization. They can be transformed into sheets, tubes, O – rings, films, and other shapes, meeting the diverse needs of different industries.
   • Tunable Composite Properties: Their formulations can be adjusted to balance flame retardancy with other important properties. For example, they can be designed to have good low – temperature resistance or conductivity, catering to specific application requirements.
