K-FLEX® ST products meet all the requirements demanded by civil and industrial refrigeration, air conditioning, plumbing, insulation of tanks, fittings, water pipes and all other applications that need thermal insulation.
K-FLEX ST TUBES is suitable for all applications both civil and industrial that require the use of insulation material, without neglecting the price/quality relationship, refrigeration, air-conditioning, heating and plumbing, tanks, pipe fittings and water ducts.
K-FLEX® products cover a range of temperature for applications including cryogenic plants to chilled
water systems, and from domestic hot water systems to solar thermal plants. Their high resistance to water vapour diffusion is a key feature of all K-FLEX® closed cell elastomeric insulation materials.
Typical applications include:
