The best UV transmission anywhere
Your Clear Advantage
Exceptionally transparent to UV and visible light, TOPAS® COC is the clear choice for diagnostic and analytical applications. We produce TOPAS grades with transmission at wavelengths as low as 220 nm, superior to other polymers. For transmission in the UVA and UVB ranges, and even the upper part of the UVC wavelength range, TOPAS COC is the best polymer available.
TOPAS polymers are stiff, strong, chemical and heat resistant. Purity is extremely high, as indicated by the numerous high-end medical applications for this family of products. The high flow of TOPAS medical grade resins enables complex, precise parts to be produced with exceptional reproducibility and dimensional stability. Diagnostic and analytical applications for TOPAS medical plastic abound, because the trend toward smaller devices and higher throughputs makes TOPAS COC an essential material for high performance products when UV transmission is vital.
