Custom silicone sheeting and film, manufactured by Trelleborg Healthcare & Medical to meet customer specifications, serves a variety of medical uses:
Our silicone sheeting and film has the following characteristics:
High consistency rubber (HCR) is formed into various types of sheeting using a calendaring process, in which the silicone is fed through multiple rollers to produce a film of uniform thickness. The film is then transferred onto a carrier sheet and may be cured or left uncured. The calendaring process can produce a range of sheeting products including combinations of vulcanized, unvulvanized, reinforced or non-reinforced products. Calendared sheeting may be pigmented and a number of surface finishes are possible.
Our HCR calendared sheeting is available with the following properties:
Our knife coating equipment and processes produce sheeting and films from different silicone materials including liquid silicone rubber (LSR), dispersions and gels. In this process, a vacuum-assist system secures a plastic film against a precisely levelled carrier belt. Silicone material is pumped at a precise rate behind a vertical blade. As the film advances, the blade spreads the silicone into a film of the desired thickness. The carrier plastic and silicone then advance through a hot air vulcanizing (HAV) chamber where the rubber is vulcanized. A protective top sheet, fed from a reel outside the HAV, is automatically and continuously applied to the upper surface of the cured film. And finally, the cured sheeting is spooled as finished product.
Our LSR knife coated sheeting is available with the following properties:
