Maleic Anhydride Grafted PP Wax

Short Description:

Propylene maleic anhydride copolymer, with SAP # of 18, in pastille form. The functionalization of a non polar polypropylene, with maleic anhydride, provides the low molecular weight copolymer with both non polar and polar characteristics. The grafting of maleic anhydride provides polarity without polymer degradation, such as oxidation will. The maleic anhydride provides the ability to boost adhesion making it very suitable for adhesive applications, including those that are aqueous. The low level of maleic anhydride, aids thermal stability versus the competition and more highly maleated products. Used as a coupling agent in composites and filled polymer systems.

Packing: 2 5 kg/ bag, PP or kraft paper bags

Applications and Functions

1.Polymer coupling agent: used for wood powder, wood fiber, glass fiber, talc, calcium carbonate, mica, aluminum hydroxide (magnesium) and other filler polypropylene composite materials, improve the compatibility and adhesion of the polypropylene matrix and filler interface. Adding the right amount, it can greatly improve the mechanical properties and thermal resistance of the composite material.

2.Polarity enhancer: used to increase the polarity of polypropylene. A small amount of addition can significantly improve the colorability and paintability of polypropylene.

3.Dispersion accelerator: used for polypropylene filler masterbatch, color masterbatch, flame retardant masterbatch, degradation masterbatch, etc.. Because of its strong interaction with pigments, dyes, flame retardants, etc., it can promote the dispersion of pigments, dyes, flame retardants, etc. in the polypropylene carrier resin.

4. Polymer compatibilizer: used in PP/PA, PP/PE and other PP alloys, add 3%~5% to improve the compatibility and affinity of phase interface.
