Shanghai, China – Additives producer Evonik will highlight a number of new products for the polyurethane industry at the PU China show. The company said these are designed to overcome a number of important problems.
It has a range of new products that have been optimised to reduce VOC emissions in flexible foam applications. These include Tegotab B8244, which has minimised cyclic siloxanes ,and is designed for demanding applications. Dabco NE 750, a gel catalyst, and Oregol 700/1/2 products to help foam recovery, are for the bed-in-a-box market.
For the rigid market, Tegostab B 84831 can, the company said, help significantly reduce the K factor of rigid foams, and B84828 improve the surface performance of foam used in metal-faced panel applications.
Evonik will also be showing three developments for the automotive sector. Tegostab B 8734 Lo and B 8761 Lo are silicone surfactants designed to help OEMs meet stringent odour and emission targets. They also have good emulsifying properties, and can operate with a wide degree of process latitude, the company said.
Ortegol LA 3 formaldehyde and acetaldehyde scavengers will also be on display.
As well as these products for flexible and rigid foams, Evonik will display products aimed at the CASE and footwear sectors, and a product to improve the hydrolysis resistance of foams.
Kosmos MB bismuth and zinc-based gel catalysts will be shown as alternatives to tin-based systems in the CASE sector. And Tegostab B 8966 is designed to help cell opening in shoe sole formulations. It is aimed a very low density systems, and where double skinning needs to be avoided.
Finally, Ortegol SE201 will be available for formulations based on TPU or polyester polyol technology where hydrolysis must be resisted.
PU China/ UTECH Asia is being held at the Shanghai World Exhibition and Conference Centre 28-30 July.
