EPDM Elastomeric Foam Sheet Insulation (Roll)​​​​​​​

​Product Overview

HVAX HT Elastomeric Foam Sheet Insulation is a flexible, closed-cell insulation material manufactured from EPDM (Ethylene Propylene Diene Monomer) rubber. It is designed for energy-efficient thermal insulation in high-temperature applications, including selected industrial systems and domestic solar heating systems.
With an operating temperature capability of up to +150°C, HVAX HT provides higher temperature resistance than standard elastomeric insulation products. It also offers improved resistance to ultraviolet (UV) radiation compared with conventional elastomeric insulation; however, for outdoor applications, protective cladding is recommended.

HVAX HT Elastomeric Foam Sheet Insulation is suitable for:
  • Domestic solar heating systems
  • High-temperature piping and equipment
  • Industrial thermal insulation systems
  • Selected applications requiring higher temperature resistance
  • Indoor and outdoor installations with appropriate protective cladding

Applications​​​​​​​

High-Temperature Resistance: Suitable for applications with operating temperatures up to +150°C.
EPDM Construction: Provides good thermal stability and resistance to environmental conditions.
UV Resistance: Offers improved resistance to UV exposure compared with standard elastomeric insulation.
Energy Efficiency: Helps reduce heat loss and improve the energy efficiency of insulated systems.
Long Service Life: Under appropriate operating and installation conditions, the insulation can provide a service life of more than 30 years.
Low Water Absorption: Closed-cell structure provides low short-term water absorption.
High Water Vapor Resistance: High resistance to water vapor diffusion helps protect the insulation system against moisture penetration.
Flexible Installation: Supplied in roll form and suitable for insulating pipes, equipment, and irregular surfaces.
