Mica: Improved Stiffness and Heat Performance

At Washington Penn Plastic, we custom formulate materials to meet your specific property requirements.  Mica-filled polypropylene offers increased stiffness and heat resistance – even more so than talc!  In addition, the pearlescent nature of mica allows special effects to be visible in the final product.  As such, mica is commonly used in packaging and housewares applications where stiffness, high heat performance and appearance are all equally critical.
