Products Description
The maleic anhydride moiety in MAPP acts as a polar functional group that can react with or adhere to other polar materials, such as polyamides, polyesters, or cellulose fibers. At the same time, the polypropylene backbone of MAPP retains its nonpolar character and can interact with other nonpolar polymers, such as polyethylene or polybutylene.This product can be used as a surface improver for extruded sheet or extruded sheet, which can effectively improve the surface flatness of sheet or sheet, and eliminate the unevenness and pitting on the surface of the material.
Therefore, MAPP can improve the interfacial adhesion and compatibility between dissimilar polymers, reduce the phase separation and mechanical degradation, and enhance the overall properties of the blend or composite, such as stiffness, toughness, impact resistance, or thermal stability.
By improving the compatibility, mechanical characteristics, and processability of polymer blends, the Polypropylene Compatibilizer provides outstanding value and performance. This compatibilizer transforms the performance of polymer blends with its polypropylene matrix, chemical reactivity, interfacial adhesion promotion, and rheological control. Prospective customers can get better compatibility, enhanced mechanical qualities, versatile compatibility, and a broad application range in industries including consumer products, construction, automotive, and packaging by integrating this compatibilizer into their manufacturing processes.
PP compatibilizer (B1) is prepared by grafting maleic anhydride to polypropylene, because it introduces a strong polar side group (maleic anhydride) into the main chain of polypropylene, so maleic anhydride grafted Polypropylene can be a bridge to improve the adhesion and compatibility of polar and non-polar materials.

Characteristic
In the application of PP+glass fiber modification, it can react with the surface-treated glass fiber to improve the compatibility of PP and glass fiber, thereby improving the tensile strength and impact strength of polypropylene. Adding PP compatibilizer in the production of filled polypropylene can greatly improve the affinity between fillers and polypropylene and the dispersion of fillers.

- Polypropylene Matrix: The compatibilizer is built upon a polypropylene matrix, which provides good compatibility with a range of polymers and thermal stability. This special characteristic makes it possible to blend and combine various polymer components in an efficient manner.
- Promotion of Interfacial Adhesion: In blends, the compatibilizer helps to create a strong interfacial adhesion between various polymers. This characteristic lowers phase separation and boosts overall performance by greatly improving the polymer blends’ compatibility, dispersion, and mechanical qualities.
- Chemical Reactivity: The compatibilizer reacts with various polymers in blends due to its high chemical reactivity. This reactivity promotes effective compatibilization and coupling, which enhances the performance and characteristics of the blend.
- Rheological Control: The compatibilizer provides viscosity and melt flow control, among other desirable rheological qualities. This feature facilitates better blendability and processability when combined with other polymers.
- Improved Compatibility: The compatibility of various polymers in blends is significantly improved by the Polypropylene Compatibilizer. It results in more homogeneous and high-performance materials by reducing phase separation, improving dispersion, and enhancing the mechanical characteristics of the blends through the promotion of interfacial adhesion.
- Versatile Compatibility: A variety of polymers, such as polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), and polyamide (PA), show broad compatibility with the compatibilizer. This adaptability broadens the scope of possible applications by enabling the improvement of different polymer blends.
