Uses the hot splicing/vulcanizing process to chemically bond two ends of a rubber extrusion together. By creating an endless seal, the gasket is more impermeable to the elements. Monroe Seals can vulcanize extruded rubber into circles, squares, and a variety of other shapes. From simple spliced O-rings, vulcanized window gaskets and vulcanized frame gaskets, to spliced seals and vulcanized corners, we can manufacture the right endless gasket for your requirements.

Calendering processes involves forcing rubber softened by heat into the center of two to five counter-rotating rollers. The rollers will compact the rubber as it passes through them and thickness will depend on the gap between the cylinders. After that the sheet passes over rollers that cool, the rubber (or other material) is often spooled. READ MORE
