Styrene-Maleic Anhydride Copolymer as Compatibilizer for PC/ABS Alloy
COACE integrating R&D, production, and sales of polymer materials, specializing in R&D, production, sales, and service of plastic compatibilizers and impact modifiers., Polypropylene and glass fiber compatibilizers, Polyamide tougheners, and plastic alloy compatibilizers .
Coace® KS-01 is a styrene-maleic anhydride copolymer.
Combining the stiffness and transparency of polycarbonate with the toughness and processability of ABS, styree-maleic anhydride copolymer is a high-performance polymer alloying agent. Alternating styree and maleic anhydride units in the copolymer's structure creates reactive sites that enable robust interfacial interaction between the two base polymers.
Styrene-maleic anhydride copolymer significantly enhances the general performance of PC/ABS alloy by means of its outstanding physical and chemical qualities and compatibility. Applications of SMA have demonstrated considerable promise and benefits in numerous sectors including automotive manufacture, electronic appliances, medical equipment and construction.
1. Enhanced Interfacial Compatibility: Strong bond produced by the maleic anhydride groups in the copolymer reacting with PC's hydroxyl groups improves the PC/ABS alloy's compatibility and stability.
2. Improved Mechanical Properties: Tensile strength, impact resistance, and elongation at break of the PC/ABS mix are much improved by using SMA Copolymer as a compatibilizer.
3. Increased Thermal Stability: The copolymer's presence in the alloy increases its resistance to high temperatures, therefore qualifying it for uses demanding great thermal stability.
4. Chemical Resistance: The SMA Copolymer increases the alloy's general use in demanding conditions by helping it to resist different chemicals.
5. Enhanced Processability: Without sacrificing the integrity of the final product, the compatibilizer helps to simplify the processing of the PC/ABS alloy including injection molding, extrusion, and thermoforming.
6. Customizability: Customizing the degree of maleic anhydride integration in the copolymer allows one to fit the characteristics of the compatibilizer for certain uses.
7. Environmental Stability: The structure of the copolymer guarantees UV resistance and weatherability, therefore extending the lifetime of PC/ABS alloys in outdoor use.
