Qingdao Hengda Chemical New Material Co., Ltd.

Main Characteristics: Appearance: Colorless, transparent liquid; Purity (%): ≥99%; Density (ρ20), g/cm³: 0.960-0.980; Molecular weight: 148.2; Refractive index (n²⁵D): 1.3880-1.3980; Product Applications: Polyethylene and other polymers are modified by grafting them onto the polymer backbone using free radical initiators (such as peroxides). Silane grafting onto polyethylene to form crosslinks or vulcanization reactions utilize water to form crosslinks. This technology is widely used in commercial applications worldwide. The basic reaction sequence is: polyethylene and vinyltrimethoxysilane react (grafting) in an extruder, initiated by peroxide. The grafted polyethylene is then formed into fins. Products such as cable jacketing, wire insulation, or pipes are typically completed via a second extrusion process, where a catalyst is added for the moisture-curing step. Exposure to moisture or hot water causes hydrolysis and condensation of the silane, forming crosslinks via silicon-oxygen-silicon bonds. Product packaging: 5kg, 20kg, 200kg plastic drum or iron drum, IBC drum
