Purventis™ Reactive Flame Retardants
As regulatory frameworks continue to evolve globally, insulation producers are increasingly looking for flame-retardant technologies that can support both today's compliance requirements and tomorrow's product specifications. Against this background, solutions beyond conventional additive flame retardants such as TCPP and TEP are attracting growing interest across the PU/PIR industry.
That's why we developed the Purventis™ portfolio to help producers and downstream customers to prepare the transition to future-proof alternatives, starting today. Purventis™ offers a solution for this transition with a next-generation reactive flame-retardant technology.

Customer value at a glance
- Regulatory resilience
Forward-looking reactive alternative for manufacturers preparing for the next regulatory wave in rigid PU/PIR insulation.
- Reactive chemistry
Chemically bonds into the polyurethane matrix rather than acting as a conventional additive FR.
- Higher efficiency
Up to 20% lower input required versus TCPP and TEP in tested formulations.
- Lower emissions and migration concerns
Designed for low-emission rigid PU/PIR insulation systems. Especially superb (up to 94% less total VOC from the FR in emission chamber tests) in comparison to TEP.
- Mechanical performance
Avoids the strong plasticizing effect observed for TEP and supports improved compressive stress.
- Security of supply
Backwards-integrated, value-chain set-up. In-house raw material production.
Purventis™ comparison with TCPP and TEP
|
Decision point |
TCPP | TEP | Purventis™ |
| Regulatory outlook | Under clear regulatory pressure in PU/PIR insulation. | Perceived by some as temporary alternative, but also under concrete regulatory scrutiny. | Reactive next-generation alternative for long-term regulatory resilience. |
| Chemistry in foam | Conventional halogen-containing additive phosphorus FR. | Conventional, additive phosphorus FR. | Next-generation, reactive phosphorus FR chemically bonded into the polyurethane matrix. |
| Input level | Benchmark. | Less efficient. Higher input required e.g. compared to TCPP. | Up to 10% lower input versus TCPP and up to 20% lower input versus TEP. |
| Emission profile | Strong. Low total VOC in PIR foam tests. | Clear disadvantage of TEP. Very high total VOC contribution in the available PIR foam tests. | Lowest total VOC contribution to emissions in the available FR foam tests. |
| Mechanical properties | Acceptable benchmark. | Unwanted, strong plasticizing effect in the tested formulation. | Supports excellent mechanical foam performance and improved compressive stress. |
