TEGOSTAB

TEGOSTAB® B 84402 is a surfactant comprising a hydrolysis-resistant polyether-modified polydimethylsiloxane copolymer used in the manufacturing of rigid polyurethane foams produced with various blowing agents like water, HFC, HCHC, or hydrocarbons. TEGOSTAB® B 84402 is suitable for use in most rigid foam applications, including laminated board stock, most pour-in-place systems, spray foam, packaging, and bun stock.

TEGOSTAB® B 84519 is a non-hydrolysable polyether polydimethylsiloxane copolymer utilized in the production of rigid polyurethane and/or polyisocyanurate foams. It is soluble and retains its chemical stability in most commonly applied rigid foam polyols and also in masterbatches containing blowing agents, amines, and reactive or non-reactive flame retardants.
