In different plastic materials, in addition to reducing costs, the application characteristics of talcum powder are also different: adding talcum powder to ABS and nylon can improve heat resistance and molding shrinkage; adding talcum powder to polyethylene can improve rigidity, heat resistance, and molding shrinkage; adding talcum powder to polypropylene can improve overall strength, heat resistance, molding shrinkage, and rigidity; adding talcum powder to agricultural plastic greenhouse film can improve its thermal insulation while maintaining good light transmittance; in plastic films such as PE, PP, and PVC, talcum powder It has low hardness, good hand feel, and a refractive index similar to that of PP and PE, making it the first anti-sticking agent; high-mesh talcum powder can act as a nucleating agent in polypropylene, effectively improving the comprehensive performance of polypropylene; adding talcum powder to hollow products can reduce production costs, reduce shrinkage, improve rigidity, and increase product life; adding talcum powder to engineering plastics such as automotive plastics and pipes can improve their impact strength, improve creep resistance at high temperatures, reduce shrinkage, and give the parts better surface quality, more gorgeous appearance, and more suitable touch. Adding talcum powder to injection-molded products can significantly improve the mechanical properties of injection-molded products, reduce the depression caused by shrinkage of the gate and edge of injection-molded parts, and improve the appearance and feel. Adding talcum powder to plastics for home appliances can make them resistant to aging, sunscreen, fading, heat insulation, thermal insulation, flame retardant, and sound insulation.
