Rubber cotton (rubber insulation material), made of * * nitrile rubber (NBR)+PVC * *, is molded by mixing and closed cell foaming; The tubular finished product is called * * rubber insulation pipe * *, and the sheet is called rubber insulation board, collectively referred to as rubber cotton/rubber pipe in the industry.
✅ Core Features
- Closed cell foaming: independent and sealed bubbles, with a moisture-proof and vapor barrier layer, making it difficult for cold water pipes to condense and drip water, without the need for additional moisture-proof film; The thermal conductivity is about 0.034W/(m · K), and it can be used for insulation and cooling
- ood flexibility and elasticity: Soft and bendable, pipe bends and valves can be cut and wrapped, easy to construct; It can also absorb shock and sound
- Flame retardant grade: mainstream B1 level flame retardant (self extinguishing upon ignition) in engineering; Ordinary home decoration B2 level; Fire protection projects must be at B1 level
- Operating temperature: -50 ℃~110 ℃; Resistant to weak acids and bases, no fiber dust, relatively environmentally friendly
- Disadvantages: Long term exposure to sunlight outdoors can cause aging, and it is recommended to apply an aluminum foil outer protective layer for outdoor use
📌 main purpose
- Central air conditioning: chilled water/cooling water pipes, air conditioning copper pipes for cold insulation and anti condensation
- Water supply and drainage/solar energy: PPR hot water pipe insulation, outdoor water pipe antifreeze
- HVAC, computer room, industrial equipment pipeline insulation, noise reduction
- Energy storage, equipment tank insulation (often using rubber sheets)
📏 Common specifications of rubber and plastic pipes
- Inner diameter: 6mm~114mm (matching copper pipe, galvanized pipe, PPR pipe)
- Wall thickness：9mm、13mm、20mm、25mm、30mm（Cold water pipes are generally chosen to be thicker for insulation）
- Single length: Conventional 2 meters per piece
- Optional: ordinary black, aluminum foil faced rubber plastic tube (anti-aging, reflective)
🛠️ Supporting materials
Rubber glue, rubber specific tape, aluminum foil tape, used for joint sealing.
📋 Key selection points
- Air conditioning chilled water, damp ceiling environment → B1 grade closed cell rubber
- Outdoor outdoor pipeline → B1 level+aluminum foil veneer
- Hot water pipe/solar pipe → Confirm temperature resistance, prioritize B1
- Ordinary home decoration water pipe antifreeze, limited budget, optional B2
