LANXESS announced its Purventis platform on September 22, with Purventis Core as the first commercial product. The company describes it as a reactive, halogen-free phosphorus flame retardant for rigid polyurethane (PU) and polyisocyanurate (PIR) insulation foams.
A new platform built on an existing technology
According to LANXESS, Purventis Core builds on technology previously marketed as Levagard 2100. The company describes a reactive approach in which the material bonds into the polyurethane matrix. Its intended audience includes polyol formulators, PU systems houses and producers of insulation boards or spray foams.
This announcement identifies a commercial offering; it does not establish the performance or approval of a particular customer's finished insulation product. Supplier test results should not be treated as a universal outcome for other formulations.
Procurement perspective: make proposals comparable
The naming transition gives purchasing teams a reason to clarify which product designation and document revision appear in quotations. A structured supplier discussion can cover:
- Product identity: Confirm the exact grade and the relationship between current and previous commercial names.
- Documentation: Request current technical documents and the scope and conditions behind any comparative claims.
- Commercial scope: Separate sample arrangements, packaging, minimum order quantity and quotation validity from technical evaluation.
Procurement and technical teams can keep a shared comparison sheet so that a lower quoted unit price is not confused with a validated formulation decision. This article reports industry news and does not imply that SUMCHEMICALS represents LANXESS or holds stock of the named product.
