GENERAL DESCRIPTION
TOPAS ® is the trade name of family of cyclic olefin copolymer (COC) resins developed by Ticona. Topas COCs are made from ethylene and norbornene and can be tailored to exhibit a wide range of heat deflection temperatures (HDT) with a practical upper limit of 340°F (170°F). It is an amorphous transparent copolymer possessing a cyclic olefin structure. The high purity and absence of ionic content in these materials provide high insulation resistance and very low dielectric loss. They also have excellent chemical resistance to aqueous acids and bases and to most polar solvents.
TOPAS is recognized as a resin with optical properties comparable with PMMA (polymethyl methacrylate, acrylic resin), superior heat resistance to PC (polycarbonate), and superior dimensional stability to both PMMA and PC. Topas COCs have a very high moisture barrier, low water absorption, good resistance to hydrolysis and chemical media, and low density. In addition, they typically offer high transparency extending into the UV range, low birefringence, adjustable heat deflection temperature and high rigidity.
* NOTE *
At this time, Topas COC is NOT AVAILABLE in sheet/plate form,
but ONLY in very limited quantities of 2½ inch diameter rod.
Some of our customers have had difficulty producing good parts.
Please contact us for more details on cutting and machining
Topas COC before evaluating this material in your application.
We do NOT sell Topas in resin, pellet or powder forms.
Examples of applications for Topas ® COC plastics include films for pharmaceutical and personal health care blister packs, food packaging, medical syringes and vials, diagnostic articles, optical lenses, light guides, and optical sensors. NOTE: All Topas grades are approved for food contact in Europe (EU Plastics Directive 2002/72/EC) and the USA (FDA 21CFR § 177.1520 "Olefin polymers").
TOPAS 6015S-04 GRADE Topas ® 6015S-04 Cyclic Olefin Copolymer (COC) has good temperature capability with a heat deflection temperature of 320°F (160°C). It is most suitable for products requiring dimensional stability due to repeated sterilization or temperature cycles, such as medical trays or instruments.
