Rubber sheet application:

Rubber sheet are widely used as different kinds of vapor pipeline heat preservation, heat insulation in central air conditioning engine room, wind pipeline heat preservation and heat insulation and etc. It has good resisting dew-together capability, sound and shock absorption, low density, thermal conductivity and low water vapor transmissibility.

It is ideal for applications in:

Ductwork

Dual temperature and low pressure steam lines

Process piping

Air-conditioner, including hot gas piping
