Zotefoams plc (LSE – ZTF) is the world’s leading producer of lightweight, cross-linked, closed-cell block foams.
These pure, consistent foams are manufactured using a unique environmentally friendly nitrogen expansion technology. Zotefoams was the first to develop cross-linked polyolefin block foams and is increasingly using its production technology to manufacture foamed materials based on high-performance polymers.
Based in Croydon, U.K., Zotefoams also manufactures in Kentucky, U.S.A. and markets its products worldwide through a global sales network.
Azote® is the group brand for polyolefin foams while Zotek® is the brand for foams based on fluoropolymers, polyamides and advanced engineering polymers.
Closed Cell Foam
Closed cell foams are used extensively in packaging applications to provide lightweight protection and impact resistance. Zotefoams unique nitrogen saturation manufacturing technology produces foams with an outstanding combination of physical characteristics unmatched by foams produced with other expansion technologies.
Azote foams have a higher strength to weight ratio than most other foams enabling lighter grades to be used and thinner protection to be utilised.
The outstanding purity of Azote foams ensures that they are non-staining and will not harbour microbial growth and will not cause corrosion. These features make them a natural choice for many returnable transit packaging applications.
Cross-linking gives a foam enhanced physical properties… making it stronger for longer. Durability and long life are essentials in many returnable packaging applications and Plastazote cross-linked polyethylene foams are used widely in closed loop systems, particularly in the automotive industry.
Cross-linking also enables these foams to be moulded and thermoformed into both simple and complex shapes. This can be of great use in the production of tote inserts where part numbers, legends and logos can be thermally imprinted in the foam surface.
The rich colour depth, along with the consistent cell size and structure gives Azote foams aesthetic appeal. This, combined with exceptionally low odour has led to them being used in many prestige, luxury retail packaging applications.
Typical uses are for packaging perfumes, drink, glassware and other breakables. These foams may be used solus or in combination with a wide variety of other packaging materials
The material is also the number one choice for case inserts where it’s appearance combined with its ability to resist compression and provide “grip” is much valued.
