Maleic Anhydride Modified Polypropylene as Compatibilizers for PA and PP
COACE's main products are compatibilizers, tougheners and functional additives, which are used in: modified plastics, wood-plastic profiles, low-smoke halogen-free flame-retardant cables, PP extruded sheets, PE extruded sheets, and anti-corrosion pipes Coatings, hot melt adhesives, photovoltaic film additives and other fields, among which special products such as nylon ultra-low temperature toughener, polyester compatible toughener, alloy compatibilizer have reached the domestic advanced level.
Coace® B1A is a maleic anhydride modified polypropylene with high grafting rate.
Maleic anhydride modified polypropylene (MAPP) is a specialised polymer that combines polypropylene's characteristics with functional groups added by maleic anhydride. This alteration increases the compatibility of polyamide (PA) and polypropylene (PP) in polymer blends, resulting in improved mechanical, thermal, and processing properties.
MAPP functions as a compatibilizer, creating chemical connections or physical contacts between PA and PP phases in a blend. It forms a bridge between the immiscible polymers, lowering interfacial tension and increasing interfacial adhesion. As a result, MAPP improves PA dispersion in PP matrices, resulting in higher mix homogeneity and mechanical qualities.
MAPP increases the tensile strength, impact resistance, and toughness of PA/PP blends by optimising interfacial interactions and minimising phase separation.
Improved Thermal Stability: The addition of MAPP increases the thermal stability and resistance to heat ageing of PA/PP blends, broadening their potential uses in a variety of temperature-sensitive sectors.
MAPP enhances melt flow properties in PA/PP blends, lowering melt viscosity and increasing processability. This enables easier extrusion, injection moulding, and other processing procedures.
MAPP increases chemical resistance in PA/PP mixes, making them appropriate for use in harsh chemical environments.

Quality & Innovation & Globalization, the slogan of COACE Chemical Co., Ltd. As it said, stability and precision become the characters of each member in COACE.
Since 2009, born in the southeast of China, Xiamen Economic Zone, COACE started her journey in the plastic industry.
With high intellectuals' team and advanced facilities, COACE focuses on the R&D and producing of the plastic additives. The factory owns 12,000 square-meter area and is equipped with eight modern extruding-pellets systems production lines, which ensure the annual capacity of ten thousand metric tons. The products cover compatibilizers, coupling agents, impact modifiers, and other functional additives.
As COACE's knockout products, the Polypropylene and glass fiber compatibilizers, Polyamide tougheners, and plastic alloy compatibilizers help the company to predominate the national market in a short time, and developed the overseas market then. From Northeast Asian economic belt to North America, COACE's products got the high evaluation from the markets.
In the past ten-year, COACE brought values to her customers, and in the following decades, even centuries, COACE aims to create values for you. COACE, material boosting performance.
COACE Products Type
COACE's R&D and manufactures focus on chemical modified high molecular weight polymers and some inorganic small molecule chemical additives. Most of her products are to be used as compatibilizer for plastic blending compounds, coupling agent for plastic compsite materials, hot-melt ahesive materials, adhesion promoters, and other application.
