Polydispersed Particles, High Heat-Resistance Grade, "KMR” and "KSR” series

Product Description

Chemisnow™ high heat-resistance grade KMR and KSR series consists of fine particles with a diameter of 3 μm, developed using our proprietary polymerization technology. They have wide particle size distributions and a high degree of crosslinking. They have extremely high resistance to heat, solvents, and yellowing, and can be used even for polycarbonate resins with high kneading temperatures. They are widely used within the field of optics, where high quality is required, owing to their high transparency and ability to diffuse light, and the KSR Series in particular has a relatively high refractive index.
