Polyplastics TOPAS® 8007S-04 Cyclic Olefin Copolymer (COC)
Categories:	Polymer; Thermoplastic; Cyclo Olefin Polymer
Material Notes:	TOPAS® 8007S-04 is a general purpose injection molding grade. It is a glass-clear amorphous polymer with outstanding moisture barrier, chemical resistance, high purity and a non-reactive surface making it an excellent choice for healthcare and other high-tech products. Lower leachables and extractables of TOPAS COC preserve food and drug stability and quality. Analytical results are more accurate with TOPAS COC in contact with sensitive chemistries. Key applications and attributes: Drug delivery: Low leachables & extractables, low water transmission Prefilled syringes, vials, cartridges: Non-ionic, does not promote adsorption like glass Bottles and tubes: Minimally reactive, EtO and irradiation sterilizable Surgical instruments: Chemically resistant to alcohol, acetone, and acrylates IV containers and components: Transparent, withstands EtO and gamma sterilization Labware:Temperature resistance, clarity and purity Optics: Clarity, low birefringence, low moisture sensitivity Electronics: Low dielectric constant, thermoplastic Food packaging: Not manufactured with BPA, phthalates, or halogens Healthcare and food: Broad regulatory approval Information provided by Polyplastics USA, which merged with TOPAS Advanced Polymers in 2018.
