Topas® 8007S-4 Cyclo olefin copolymer Granules

Grade: Topas® 8007S-4
Formula: COC Topas®
Form: Granule
Material: Cyclo olefin copolymer (COC)
CAS Number: 26007-43-2
Commodity: Polymers
Nominal Granule Size: 3mm
Topas® 8007S-4 COC granules are widely used in medical device housings, diagnostic equipment, and microfluidic systems, owing to their exceptional dimensional stability, low moisture uptake, and resistance to autoclaving, gamma irradiation, and E-beam sterilization. The polymer’s low birefringence and superior optical clarity make it an ideal choice for high-performance optical and imaging applications, including spectroscopy and biosensors. With an extensive processing window, it enables the production of complex, durable components for pharmaceutical research, bioassays, and precision diagnostics in both biotechnology and life sciences industries.
