Microlen PE45X is a low-to-medium-density foam material, with a density of 41-51kg/m3.
Microlen PE45X is a robust, highly stable closed-cell cross-linked polyolefin foam. Its properties make it suitable when material toughness, retention of structural form, and low thermal conductivity are required. As such, it is typically selected over lower-density grades (such as PE30X) when a stiffer, higher-performing cushioning barrier is needed to protect heavier products or technical gear. Manufacturers and distributors frequently use Microlen PE45X as a reliable supportive layer in custom packaging, structural void-fill insulation, and heavy-duty surface protectors.
Our team of foam experts at Polyformes can provide free and impartial advice on the best foam grade and type for your specific product, industry, and application. We can also supply raw material or converted products as 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 PE45X 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.
