Microlen PE20X is a popular mid-density standard option in the Microlen range, with a nominal density of 37-47kg/m3.
Microlen PE20X is a highly flexible, skin-safe, closed-cell cross-linked polyolefin foam. These properties make it a versatile, high-elongation option for applications requiring excellent thermoformability and soft tactile feedback. It offers improved weight, buoyancy, comfortable touch, and efficient thermal conductivity compared to denser, more rigid technical grades. Microlen PE20X is popular for the production of aquatic recreational gear (such as swimming floats), orthopaedic orthotics, and general industrial gaskets.
At Polyformes, we are official distributors of Microlen foams in the UK. In addition to supplying sheets or buns of material at the exact size(s) you need, our in-house conversion equipment enables us to provide a range of custom foam inserts and products.
Please note that this technical information on Microlen PE20X does not constitute a guarantee of performance, and is provided for guidance only. Please contact our foam experts for further advice if required.

Polyformes can split/skive, laminate and butt-weld Microlen material to the specific dimensions you require. You can also select skin or cell finishes. MOQs may apply to certain size/material options.
Please get in touch with a member of our team to discuss your requirements.
Microlen PE20X 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.
