PU TECH 2011: Air Products

For flexible moulded foam applications the company will present its Dabco series NE 300 blow catalyst, NE 210 balanced catalyst, NE 1070 gel catalyst, BA 100 blocking agent, CL 420 crosslinker, and DC6070 silicone surfactants for TDI and TM systems as well as DC2525 for MDI systems. These products bind chemically into the PU foam matrix while maintaining foam properties and when used in automotive applications, catalyst contribution to odour and emissions causing windshield fogging and vinyl staining are eliminated. New catalysts for fast demoulding include Dabco MP601 delayed action balanced catalyst and MP602 delayed action non-fugitive catalyst for improved skin cure.

Products of the Dabco series presented for flexible slabstock applications include RP204 balanced catalyst for ultra low to high foam density and DC5906 non-fugitive silicone surfactant. They reduce odour and can be used to produce products that meet Certi-PUR requirements. Dabco DC5950 and DC5986 flame retardant silicone surfactants enable to meet the requirements of BS5852 Crib 5 tests (DC5950) and CAL 117 tests (DC5986).

For construction applications, the company will highlight LK221 and LK443 non-silicone organic surfactants for rigid and microcellular PU formulations. Dabco PT series catalysts are amine catalysts for rigid spray foam, providing low odour. The LK series surfactants and Dabco PT series catalysts are used in rigid foams with low k-factors, high percentage of closed cells, high dimensional stability, adhesion strength, and smooth surface.

For appliance applications, Air Products will present Dabco BX405 and BX406 catalysts, that accelerate the demould time and improve adhesion. Products showcased for shoe sole applications include Dabco DC 3042 and DC 3043 surfactants, that provide fine, uniform cell size distribution, good surface quality, dimensional stability as well as enhanced flowability. Dabco XD102 catalyst improves flowability, KTM-60 and 1027 catalysts provide faster demould properties, and XD104 prolongs cream time and improves the surface quality with shining skins.

Air Products will present two papers at the conference, titled: "Building Quality Rigid Polyurethane Foam with Air Products Additives" and "The leading additives to support the further success of Polyurethane Industry".
