Elastomeric Rubber ST / SK Tubes

Description

K-FLEX ST/SK TUBES is a cut -to-length self-seal elastomeric insulation. This innovative technology includes adhesive tapes which are quick and easy to use for the installer. This new system has been developed to save on insulation time and reduce the use of other adhesives to improve working conditions at the construction site. Also available as version with overlap-K-FLEX ST/SK with overlap.

General Information

• Elastomeric insulation for all civil industrial applications
• High performance for all applications in a temperature rang from -165C TO 110C
• Prevents the risk of condensation and improves energy saving
• Reaction to fire Euroclass B-s2, d0
• Very fine closed cellular structure and high technical performance
• Resistant to mould, fungi and bacteria

Applications

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:

• Refrigeration and air-conditioning systems and plumbing.
• Industrial, chemical and pharmaceutical plant engineering.
• Insulation of pipes, fittings and other equipment.
• Insulation of tanks, solar systems.
• OEM applications.
