Silicone Sheeting Manufacturing Processes
We produce sheeting using two different methods:
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 is capable of producing a variety of sheeting 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 knifecoating equipment and processes produce sheeting and films from a number of 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 advances 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. The cured sheeting is then spooled as finished product.
Trelleborg Sealing Solutions knifecoating capabilities are unique and offer several advantages over the more widely used calendaring process.
Our knifecoating technology is leveraged in our line of custom dermal adhesive gel products which are widely used in applications involving wound management and scar reduction.
Our LSR knifecoated sheeting is available with the following properties:
