Addovate® 390 by LANXESS is a non-hydrolyzable silicone stabilizer for the production of PUR rigid foam. It is a very versatile stabilizer of medium to high activity with additional excellent emulsifying properties. The reduction of cell defects and reliable stabilization can be achieved in both slow and fast systems. It can also act as a blowing agent. It finds application in insulations of appliances, pipe insulations, continuously or discontinuously produced panels and cavity foaming. Recommended dosage level is 2 parts by weight on 100 parts by weight polyol. Addovate® 390 has a shelf life of 12 months. Addovate® TX by LANXESS is an ionic emulsifier or stabilizer for the production of PUR ester flexible slab-stock foam. It is used in combination with Addovate® TX to achieve good foaming control resulting in fine cell structure. Recommended dosage level is 1-3 parts by weight to 100 parts by weight polyester polyol. It has a shelf life of 12 months. Addovate® EM by LANXESS is a non-ionic emulsifier designed for PUR ester flexible slab-stock foam. It functions as an emulsifier for water, catalyst and polyester polyol. It improves the open-cell structure of foams. It is used in combination with Addovate® EM and small amounts of silicone stabilizers for the production of foam for textile applications. Recommended dosage level is 1-4 parts by weight to 100 parts by weight polyester polyol. It has a shelf life of 12 months. Addovate® OM by LANXESS is a dispersant for the production of polyurethane ester flexible slab-stock foam. It is available in brownish liquid form. Addovate® OM has a shelf life of 12 months. Addovate® WM by Lanxess is a non-ionic dispersant or emulsifier for the production of PUR ester flexible slab-stock foam. It is used in combination with Addovate® SM. It is designed to homogeneously disperse water, water-insoluble catalysts and paraffin oil in the activator batch and to aid the mixing of reaction components in the mixing chamber. Recommended dosage level is 1-2 parts by weight to 100 parts by weight polyester polyol. It has a shelf life of 24 months. Addovate® SM is an aqueous solution of fatty acid sulfonate. Acts as an emulsifier/stabilizer for the production of polyurethane polyester flexible slabstock foam, rigid foam as well as a crosslinker for cellular hot casting elastomers. Is used in an aqueous catalyst compound in conjunction with Addocat® DB, Addovate® WM and paraffin oil. It improves the dispersion characteristics of the individual catalyst and reactant components in the mixing chamber. It primarily keeps the crosslinking reaction under control. It also has a stabilizing effect during the foaming phase. It has a shelf life of 6 months. Addovate®3240 is polyglycol ester. Acts as a specialty emulsifier for the urea catalysis used to obtain low odor polyurethane polyester slabstock foam. Since it is only partially miscible with water, it is recommended to add it separately. Dosage should be between 1.0 and 2.5 pbw Addovate®3240 to 100 pbw polyester polyol. It has a shelf life of 12 months. Addovate® Thermostab is an aromatic ester of phosphoric acid. Acts as a sterically hindered antioxidant acting against thermo-oxidative degradation which may occur during processing as a result of thermal, oxidative and mechanical stress. It is non-ionic and also acts as an anti-oxidative radical interceptor (primary antioxidant) due to its sterically hindered molecular structure. It scavenges hydroperoxides without forming colour bodies in a stoichiometrical reaction by forming alcohol, simultaneously oxidising the phosphite to the corresponding phosphate (secondary antioxidant). Compatible with of PC/ABS, PA/ABS, TPU, ABS and PA against thermo-oxidative degradation during processing in the melt. It has a shelf life of 6 months. Addovate® SV is an aqueous solution of fatty acid sulfonate. Acts as an emulsifier and crosslinker for the production of cellular Vulkollan. The water component serves to promote the propellant effects. To improve dispensing characteristics, a crosslinker should be manufactured containing approx. 10 parts by weight of the polyester polyol also used for the prepolymer. The shelf life is 6 months. Addovate® BA is an aqueous PUR dispersion. Acts as a bonding agent for improved adhesion of PUR rigid integral skin foam to metal surfaces. It is applied where improved adhesion between rigid integral skin foam and metal reinforcement parts or other metal surfaces is required. It has a shelf life of six months.
