Silicone Sheeting & Film

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:

• Vulcanized, Non-Reinforced HCR Sheeting
• Vulcanized, Reinforced HCR Sheeting
• Unvulcanized, Non-Reinforced HCR Sheeting
• Unvulcanized, Reinforced HCR Sheeting

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.

• Entirely closed-loop process significantly reduces the risk of particulate contamination due to environmental exposure
• Continuous manufacturing process capable of producing larger batch sizes at lower cost
• Sheeting thickness is more precise, accurate, reproducible, and capable of producing silicone film as thin as 0.025mm / 0.00098 inches

Our LSR knife coated sheeting is available with the following properties:

• Non-Reinforced LSR Sheeting
• Reinforced LSR Sheeting
