COCs are used in combination for pure products that require a low leachables and extractables profile. Elastomer E-140 can be overmoulded onto rigid Topas grades or other olefinic grades and achieve hermetic seals. Overmoulding can elimi- nate costly secondary operations in assembly while eliminating potential leaching issues derived from adhesives or solvents in the bonding process. “Topas standard grades are rigid with low
leachables and extractables. However, wearables can require some flexibility depending on the design. The newest Topas products are Topas standard grades tempered with Topas Elastomer E-140. This method offers a 100% cyclic olefin chemistry without dissimilar polymers or additives that could be a potential cause for concern from a leachables standpoint. Tempering rigid Topas resin with flexible Topas Elastomer E-140 is a unique approach for the marketplace. Flexibility can be designed into the resin mix by tempering to achieve a designer stiffness and the exact refined requirements.” Specifically, Topas 8007S-04 is a resin with low
autofluorescence and light transmission that goes down to 340 or 330 nm. It is used in many Topas COC applications, including optical. Topas 8007X10
is a special material that extends light transmission to 250 nm. It was developed for plastic read-through applications in the UV region. This area will grow over time, using the plastic read-through benefits and the high purity of Topas COC. As patient infections increase in the hospital environment, there is a need to maintain sterility especially in high-con- tact areas for enhanced patient safety. UV disinfec-
