Microlen PE45XL, with a density of 41-51kg/m3, is supplied in oversized sheets to improve conversion efficiency.
Microlen PE45XL is a structurally firm, robust, closed-cell cross-linked polyolefin foam manufactured in very large physical block dimensions. Its size alone makes it a high-efficiency option for applications requiring wide-format, continuous protective cushioning and high-dimensional stability. It is particularly suited to producing continuous layouts in a single piece, eliminating the need for visible laminated seams. Manufacturers and distributors typically use Microlen PE45XL to create large-scale protective surface wraps, premium athletic mat cores, and wall insulation sheets.
As well as the right material, maximising yield on large-format sheets requires the right conversion technology. At Polyformes, we combine extensive material stockholding with cutting-edge equipment to deliver custom, large-scale foam inserts and products of the highest quality.

Microlen PE45XL foam sheets are suitable for conversion using the following processes:
Although similar to Plastazote® in structure, the different manufacturing process for Microlen (chemical vs physical cross-linking) makes it more suited to the below applications. Please note, however, that this list is not exhaustive – if you cannot see your intended application, please get in touch to discuss your options with our foam experts.
By sourcing your foam material from Polyformes, you can expect several benefits.
