The thermal performance of a rigid polyurethane insulation board is set by its cell structure: fine, uniform, closed cells limit heat transfer and keep the board dimensionally stable. Evonik's catalysts and silicone surfactants give PUR and PIR board manufacturers control over foam reaction, cell structure, surface quality and processing.
Why Choose Evonik for Insulation Boards?
- Proven Performance: Trusted brands like DABCO® and TEGOSTAB® control foam formation and stability in rigid insulation boards.
- Surfactants for Low Lambda Values: TEGOSTAB® B 84522 and B 84523 are silicone surfactants for highly catalyzed flex-faced and metal panel formulations, designed to deliver the lowest lambda values in these systems.
- Tailored Innovation: Grade selection is matched to your polyol and blowing-agent compatibility, catalyst level and facer type.
Solutions by Application
Rigid Polyurethane Insulation Boards
- DABCO® – Catalysts for controlled PUR and PIR foam reactions that support uniform cell structure. DABCO® TMR 16 and TMR 23 are trimerization catalyst packages for continuous and discontinuous PIR production, and DABCO® TMR 32 is a co-catalyst that promotes curing and dimensional stability. All three are designed for formulations requiring the absence of 2‑ethylhexanoic acid (2‑EHA), whose salts have been classified as toxic to reproduction (Cat. 1B, H360) in the EU since December 2023.
- TEGOSTAB® – Silicone surfactants that regulate cell structure for consistent quality, surface finish and dimensional accuracy in insulation boards.
