Product overview: lightweight foam materials from Zotefoams

Lightweight insulation material by Zotefoams

From AZOTE to ZOTEK and beyond

Zotefoams uses its unique, environmentally friendly production technology in a number of ways, all of which create lightweight foam materials that have environmental, safety or other performance benefits.

Our nitrogen expansion autoclave technology is used to create AZOTE® polyolefin and ZOTEK® high-performance block foams with exceptional cell size uniformity, low odour, high purity and outstanding physical properties. The qualities and consistency of these foams deliver benefits during foam conversion and also in end-use products where our unique attributes add value in many applications.

We use our own ZOTEK foams to manufacture T-FIT® insulation, used in some of the highest-standard clean and aseptic production environments globally.

Through our MuCell Extrusion LLC business we offer our proprietary environmentally friendly high-pressure gas technology to the plastic extrusion market: this allows significant material and weight reduction for applications in consumer packaging, such as flexible films, bottles and containers.


Zotefoams’ range of high-specification closed cell, crosslinked lightweight foam materials is divided into two families: AZOTE and ZOTEK.


AZOTE foams, Plastazote®Evazote®and Supazote®, are polyolefin foams based on a wide range of polymers, and come in a variety of colours and densities.
AZOTE® foams are used in numerous industries for a broad range of applications that include product protection, cushioning, and impact resistance – particularly where light weight, durability and resistance to specific chemicals or water are important.

Foams from the AZOTE range are generally supplied via our global network of specialist converters.


ZOTEK foams, ZOTEK F, ZOTEK N and ZOTEK T, are high-performance products for specialised applications. They are manufactured using fluoropolymers, engineering polymers and speciality elastomers.

ZOTEK foams are used extensively in industries such as aviation, aerospace, and automotive manufacture, where they are an important part of many high-performance solutions.

ZOTEK foams have a variety of unique characteristics dependent on their base polymer. These include:

  • Thermal, chemical and radiation resistance
  • excellent flammability performance
  • resistance to swelling from contact with hydrocarbons such as oil

T-FIT foam insulation system

T-FIT is an insulation system specifically designed for ‘cleanroom’ applications. T-FIT Clean products are the only foams currently compliant with the demanding FM Approvals 4910 standard for cleanroom management.

MuCell® technology

MuCell® technology injects inert gas into plastic extrusions during manufacture. This creates a microcellular structure in the core of the material which is bounded by solid skins. The result is a lightweight foam material that offers identical performance characteristics to solid counterparts but with significantly reduced polymer content.
