TECAFORM® AH Calendered Sheet

Calendering is how the thin gauges are made: the acetal is drawn between heated precision rollers into flat stock of consistent thickness with a smooth finish on both faces, instead of being extruded as a thick slab and machined down. That gives better flatness and less locked-in stress than a sliced piece of plate. Stock covers 1/32" to 1/4" in eleven gauges, in sizes from 12"x12" up to 48"x120". For thicker sections, extruded TECAFORM® AH plate is the correct product.

Thin calendered acetal copolymer goes into parts that are punched, sheared or die-cut rather than machined: washers, shims, spacers, gaskets, seal faces, wear and thrust pads, slide strips, insulating pads and chute liners across food and beverage, packaging, conveyors and general automation. Copolymer chemistry handles hot water and caustic washdown better than homopolymer, which is why it dominates in wet processing. The consistent gauge is the point in stacked or sealing assemblies, where thickness variation across a sheet becomes a leak path or a preload error.
