Filler for polypropylene masterbatch, flame retardant masterbatch, polypropylene PP grafted degradable masterbatch, polypropylene and filler system to improve the adhesive coupling, thereby improving the tensile impact strength, thereby increasing the filling amount
Maleic anhydride-grafted polypropylene performance indicators:
A matrix resin: PP
Appearance: yellowish qualities particles
Grafting yield: 0.9 to 1.1mA% of
Melt index: 40 g/10 min (190 ° C, 2.16 kg)
Maleic anhydride-grafted polypropylene Typical applications:
1, polymer coupling agent: wood flour, glass fiber, talc, calcium carbonate, mica, aluminum hydroxide (Mg) filled polypropylene composite material, to improve the compatibility and viscosity of the polypropylene matrix and the filler interface then sex. Add 5% to 8%, can greatly improve the mechanical and thermal resistance properties of the composites.
2, the polarity enhancer: for increase polypropylene polarity. Add 8-10% can significantly improve the dyeability of polypropylene and paint.
3, dispersion accelerator: for polypropylene filler masterbatch, flame retardant masterbatch, degradable materials such as. Because of its strong interaction with pigments, dyes, flame retardants, etc., can promote the dispersion of pigments, dyes, flame retardants, in a polypropylene carrier resin.
4, the polymeric compatibilizing agent: PP / PA, PP / PE PP alloy, the added amount of 2% to 5% to improve interfacial compatibility and affinity.
