A continuous extrusion manufacturing process is used to create the continuous rolls of expanded closed cellular polymers to a predetermined thickness and width with usable skin on both sides. This continuous process produces consistent uniform material.
A press-cured process creates expanded closed cellular polymers in a slab or bun configuration. The dimensions of the bun are predetermined by the size of the mould the product is cured within. Manufacturing has slightly better control of cell size in this process thereby being able to produce a tighter cellular structure than the continuous process. This process works well with a wide range of polymers.
