  • Patent number: 10047212
    Abstract: The present disclosure relates to a solid curable transparent rubber composition containing a styrenic block copolymer having 2 or more poly(vinyl aromatic) blocks, a curing agent and additives. Once cured, the solid curable transparent rubber composition has a haze of less than 30% and a total light transmission of more than 80%. The disclosure further relates to a cured transparent rubber composition made thereof, and a manufacturing process for the cured composition. The present disclosure also relates to an article including the rubber composition, in particular for tubes, medical stoppers, catheters, dental dams and other medical applications and artificial nipples.

  • Patent number: 9758649
    Abstract: The present disclosure provides a process for preparing a cured transparent rubber composition containing a synthetic isoprene polymer(s), a transparent polymer(s), a curing agent and additives. The process includes mixing the components at a temperature ranging from 50 to 130° C., curing the compound with peroxide and allowing the compound to mature. The maturated compound is fed to an injection molding machine. The cured transparent rubber composition prepared using the methods described herein has a haze of less than 30% and a total light transmission of more than 80%. The disclosure further provides an article including the cured transparent rubber composition, in particular for medical applications and artificial nipples.
