Coupling agent helps disperse mineral fillers.Improved dispersion of mineral fillers in thermoplastics and EPDM rubbers is reportedly achieved with a new silane silane or silicon hydride Any of a series of inorganic compounds of silicon and hydrogen with covalent bonds and the general chemical formula SinH(2n + 2). coupling agent from Dow Coming Corp., Midland, Mich. Z-6172 Silane reportedly increases initial and wet strengths of glass-filled polyester and other resins and optimizes electrical and physical properties of mineral-filled plastics and elastomers. It has two kinds of reactive groups: organic vinyl and inorganic methoxyethoxysilyl. Alkoxysilyl groups react to form siloxane siloxane /si·lox·ane/ (si-lok´san) any of various compounds based on a substituted backbone of alternating silica and oxygen molecules; in polymeric form they are polysiloxanes, and when the side chain substituents are organic radicals, bonds to inorganic surfaces and materials, and also to other silane molecules to form a crosslinked network. The vinyl group participates in the peroxide peroxide (pərŏk`sīd), chemical compound containing two oxygen atoms, each of which is bonded to the other and to a radical or some element other than oxygen; e.g. cure of the resin or elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. system. Tel: (989) 496-7711 * PTDirect.. 169WX |
