Polyurethane insulation thermal conductivity coefficient: λ = 0.013-0.03kcal / m h oC pipe insulation, much lower than other pipe insulation material used in the past, the insulation effect increased by 4 to 9 times??. Then there is low water absorption black jacket insulation pipe manufacturers, about 0.2kg / m2. The reason is due to the low water absorption of the polyurethane foam closed cell ratio as high as 92%. Low thermal conductivity and low water absorption, plus insulation and outer waterproof good high density polyethylene or fiberglass protective shell, has changed the traditional trench laying pipe heating condition "wearing wet jacket", greatly reducing the heating pipes overall heat loss black polyethylene jacket pipe insulation, heating network heat loss of 2%, less than 10% of international standards. Polyurethane Foam has obvious advantages: 1. Polyurethane Foam has a multi-functional material polyethylene pipe insulation, along with insulation, water, noise, vibration absorption and many other features. 2. Insulation performance, is all the domestic building materials lowest thermal conductivity (≤0.024), the highest heat resistance of insulation materials, thermal conductivity is only half of the EPS foam polystyrene board.
