Microlen PE125X is a mid-to-high-density option in the Microlen range, with a density of 110-140kg/m3.
Microlen PE125X is a tough, rigid, closed-cell crosslinked polyolefin foam. These properties make it a high-end technical option in which a combination of maximum compressive strength, excellent thermal insulation, and pristine surface aesthetics is required. As such, it is preferred over lower-density materials for its ultra-firm structural support and its upscale, premium-feeling aesthetic during transit. Manufacturers and distributors typically use Microlen PE125X to produce high-end presentation packaging inserts, defensive aviation components, and complex thermoformed industrial parts.
Whether you require raw material buns or complex CNC-routed components, Polyformes has you covered. As trusted industry partners, we utilise state-of-the-art in-house conversion equipment to transform sheets of any size into tailored inserts, protective end caps, and custom-engineered packaging solutions.
Please note that this technical information on Microlen PE125X does not constitute a guarantee of performance, and is provided for guidance only. Please contact our foam experts for further advice if required.
The internal methods IE-03, IE-04, IE-05, IE-06 and IE-07 are based by standards ISO 1923, ISO 845, ISO 844, ISO 1926 and ISO 1856-B, respectively.

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 PE125X 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.
