PHRA 50 Magnesium oxide 001309-48-4 Dead Sea Periclase Catalysts / Accelerators / Vulcanizing agents >> Organometallics Extenders / Fillers >> Magnesium oxide Acid Absorber / Acceptor Chloroprene Rubber (CR) Polyesters Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE RUBBER, PLASTICS & ADHESIVES ACTIVE MgO Magnesium oxide fills several roles in the rubber, plastics and adhesives fields. In the production of polychloroprene rubber, magnesium oxide regulates the rate of vulcanization and prevents the development of "scorch". In polychloroprene-phenol resin adhesives, magnesia acts as an acid acceptor and integral part of the bonding system. Viscosity development in polyester sheet-molding compound is controlled by magnesium oxide. In all these and other acid-acceptor systems involving halogenated elastomers, fine particle size and closely controlled surface area or reactivity are vital. DSP's RA SA series meets all the varied requirements of the polymer industry. A range of highly active, pure magnesium oxide products for the rubber plastics and adhesives industries. Active magnesium oxide. Possesses high purity and activity. Used in rubber and adhesives industries. Regulates the rate of vulcanization and prevents the development of "scorch" in the production of polychloroprene rubber. Acts as an acid acceptor and integral part of the bonding system in polychloroprene-phenol resin adhesives.
