ZOTEK NB50 foam for boiler machine insulation

Introducing ZOTEK NB50

Manufactured from heat-resistant nylon, ZOTEK NB50 is a closed cell, crosslinked lightweight foam that outperforms all other types of insulation, meeting and exceeding the thermal requirements for steam boilers, with consistently high performance at 120°C and a maximum operating temperature of 205°C.

Excellent thermal conductivity properties mean that less material thickness is required than with standard insulation, allowing reduced footprint and better machine design flexibility.

Flat sheets of ZOTEK NB50 can be thermo- or vacuum-formed to fit around the boiler and hot pipework, in an easy, single-step process, reducing manufacturing time and cost.
