black rubber foam insulation continuous pipes

NBR/PVC Rubber Flex Insulation Tube

Characteristics of our rubber tubes:

1. Closed-cell Structure.

2. Low Heating Conductivity.

3. Low Water Absorption Rate.

4. Good Fireproof and Soundproof Performance.

5. Good Aging Resistance Performance.

6. Simple and Easy Installation.

Application of rubber tubes:

Rubber tubes are used to retard heat transmission and control condensation from chilled-water and refrigeration systems. It also efficiently reduces heat transfer for hot-water plumbing and liquid-heating and dual-temperature piping

Rubber tube is ideal for applications in:

Ductwork

Dual temperature and low pressure steam lines

Process piping

Air-conditioner, including hot gas piping
