Product Details

Waterproof and flame-retardant rubber insulation cottonPerformance Characteristics

Excellent flame retardant performance: Adding flame retardant and smoke reducing components to the material makes it difficult to burn when exposed to open flames, and the smoke concentration during combustion is extremely low. It has self extinguishing characteristics and can effectively prevent the spread of fire.

Waterproof and moisture-proof: The closed cell structure makes the material have extremely low water absorption rate, making it difficult for water vapor to penetrate and maintain a dry state for a long time, making it suitable for humid environments.

Good insulation effect: low thermal conductivity, can effectively reduce heat transfer, maintain system temperature stability, and reduce energy consumption.

Shock absorption and noise reduction: The closed cell structure can block the propagation of sound waves, reduce pipeline vibration, and improve user comfort.

Strong weather resistance: adaptable to a wide temperature range, able to maintain flexibility in low temperature environments, and not easily deformed or aged in high temperature environments.

Environmental protection and health: free of harmful substances such as chlorofluorocarbons, non-toxic and odorless, will not irritate the skin or harm health.

Waterproof and flame-retardant rubber insulation cottonMaintenance measures

Storage environment: A dry and ventilated storage location should be chosen to avoid direct exposure to rainwater or moisture, as well as direct sunlight to prevent surface aging.

Keep clean: The storage area should be kept clean, and the surface of the flame-retardant rubber insulation cotton should be regularly cleaned and inspected to avoid the accumulation of dust, dirt, or other impurities.

Avoid mechanical damage: During handling and storage, handle with care to prevent deformation caused by scratching or squeezing. Flame retardant rubber insulation cotton stored for a long time can be wrapped with appropriate packaging materials (such as plastic film or waterproof cloth) to increase its protection and resistance to damage.
