'SC' Coupling System Enhances The Properties Of Mica Filled Polypropylene And Mica/Glass Polypropylene Hybrid Systems

摘要

High aspect ratio mica improves the modulus and heat deflection temperature properties of thermoplastic polymers and reduces the shrink and warping of plastic composites. Tensile and flexural strength properties are usually maintained while impact properties decrease. Glass reinforced polypropylene composites offer good strength, impact and heat deflection properties; however, dimensional stability and warping of molded parts have always been a problem resulting in over engineered parts at premium costs. This study involves the development of the "SC" coupled mica system to improve the bonding between the mica reinforcement and polymer matrix so as to enhance the traditional properties provided by mica to reinforce polymers.
