K-FLEX ST Closed Cell Elastomeric Insulation is a closed cell material which provides low water absorption, stable thermal conductivity, good fire performance & ease of application.

It is ideally used for general refrigeration & heating applications as insulation against heat-loss in heating systems. (e.g. hot water pipes, solar heater installations & heat recovery systems, preventing condensation in cold lines for refrigerators, air-conditioners, drain pipes, display/bar type freezers & other refrigeration systems.)

With proper & quality usage of insulators, it helps not only assist in energy conservation but reduction in costs.
