Product benefits

Halogen-free insulation materials are becoming more and more important in technical insulation. Since they are free of PVC, chlorides and brominated flame retardants, they are particularly suited to industrial and specialist applications where toxic combustion gases are a special hazard. This includes their use in maritime, railway, airport and hospital settings.

Kaiflex HFplus s2 insulation materials are uncritically foamed, free of halogens and heavy metals, and meet smoke development class s2 and fire resistance class R90 specifications. This insulation system thus complies with rigorous European requirements for construction products for fire protection and sustainable building. It meets the required safety standards even in demanding environments.

International certifications

This halogen-free insulation material is approved for many application areas and special requirements with its international certifications. Since it is free of chloride, Kaiflex HFplus s2 prevents stress corrosion cracking and can be installed with confidence for insulating stainless steel pipes, such as those found in food and pharmaceutical production.

Kaiflex HFplus s2 is available in tube and sheet formats. The sheets also come in self-adhesive versions. Together with Kaiflex RT-HFplus s2 pipe supports and Kaiflex 494 HHF special adhesive, all components form a complete coordinated system.

Guaranteed sustainable – green light for green buildings

For Green Building certification, sustainability must be addressed in the installation of all fixtures and fittings. This naturally also applies to the insulation of technical building installations. The Kaiflex HFplus s2 insulation system fully meets the declaration criteria for low-pollution building materials. Depending on the configuration, it complies with Green Building standards such as BREEAM, DGNB and LEED, and can be used with confidence in sustainable construction.

With its specific structure, this high-quality rubber material for demanding hygienic applications also offers further health benefits. As a closed-cell insulation material, Kaiflex HFplus s2 generates no harmful particles, whether in ongoing operation or during installation and working with the material.

Environmental Product Declarations (EPD) make the ecological assessment of Kaimann insulation materials even more transparent. In this way, the company assists in the planning and certification of sustainable buildings.
