High Intensity PU pipe bracket

High Intensity PU pipe bracket is a kind of foaming polymer with the features of plastic, rubber and softwood. It is created through high speed stirring with the main raw material of isocyanate and polyether added with foaming agent and catalyst or fire retardant. It has high density, low thermal conductivity, low water adsorption and the texture is better than timber boards. It is used as pipe saddles and cradles in petrochemical industry bases, liquefied gas factories, freezers and central air conditioning both in China and other countries in Europe or America.

High Intensity PU pipe bracket

Material Properties
1 .Low coefficient of heat conductivity and good cold insulation effect;
2. Its volume is stable at ultralow pemperature(-163℃)/high temperature;
3. High compression resistance and distortion resistance;
4. Low moisture content;
5. Good flame retardance;
6.Forming through mould at high pressure,with varies thickness and number of layers to meet varies cold insulation design requirements;
7.Components such as pipe bracket are securely assembled in the plant and has long service life;
8.Easy and safe to be installed at site,not necessary to change the pipe line;
9.Standardized specifications with reliable quality and quick supply;
10.Designed with varies size for all levels of technology and economical requirements.
