Introduction:
1. This product is modified to polyethylene and other polymers by grafting to the polymer main chain, so that the side chain of the polymer has a trimethoxysilyl ester group as an active point for warm water crosslinking.
2. The advantages of polymer cross-linking are: 1) better use temperature 2) polymer decomposition when lowering creep 3) improved chemical resistance 4) excellent resistance to pressure cracking 5) improved wear resistance 6) Improve impact strength 7) Memory characteristics (shrink film and tube).
3. The advantages of silane cross-linking over irradiation cross-linking or peroxide cross-linking are: 1) Low equipment investment 2) Low production cost 3) High productivity 4) Variety of processing technology 5) Suitable for various thickness, Various complex shapes 6) Large process latitude (control premature crosslinking) 7) Suitable for filled composite materials 8) Suitable for many density polyethylene and copolymers
Application:
In the extruder, through the action of peroxide initiator, this product can be grafted to the polyethylene main chain. This grafted polyethylene can be made into shaped products, such as cable jackets and insulation, pipes or other extruded and molded products. This is the next extrusion process. This molded product is completed by warm water crosslinking.
