Aminoethylethanolamine (AEEA)
is used as a chain extender and crosslinker for polyurethanes and affects polymer properties accordingly. The product’s bifunctionality is a requirement for its use in these areas. Both the hydroxy and the amine function react very well with isocyanates.
Ethanolamines (EOA)
are used in various PU applications as chain extenders and cross-linkers. Mono-, di- and triethanolamine (MEOA, DEOA, TEOA) forms exist. DEOA and TEOA may be used as a polymerization starter in polyol manufacture. The catalytic effect also provides a means of controlling the foaming rate and subsequent curing. BASF offers a high level of supplier reliability as European market leader with full backward integration on the raw materials side and plants in Germany and Belgium. The company also has an extensive product range with a variety of solutions and mixtures. Mono-, di- and triethanolamine (MEOA, DEOA, TEOA) are produced by synthesis of ethylene oxide and ammonia. In addition to pure grades and an array of mixtures and solutions, BASF supplies a mixture of TEOA and DEOA created specially for the PU market and sold under the product name Triethanolamine PU.

Methyldiethanolamine (MDEOA)
is an amine-based polyol that is suitable for use as a PUR catalyst and as a special polyol in PUR synthesis. A double-action additive (catalyst and polyol), MDEOA is also a useful crosslinker and chain extender. BASF is the world’s only manufacturer with full backward integration covering all the raw materials contained in MDEOA.

N4-Amine
is making a name as a special catalyst in the flexible foam segment. The high amine content significantly reduces starting time. This property is an advantage when rapid foam injection is required. N4-amine is produced by addition of ethylene diamine and acrylonitrile followed by hydrogenation.
