Polyurethane Foam - the latest tank insulation material

Jul. 03, 2019

Regarding the PU Foam, it is Polyurethane foam sealing agent.Polyurethane foams are one of the best insulation materials known today. PU foams offered by Ceresit are simply, conveniently and efficiently usable solutions. High quality PU foams have: Low thermal conductivity´╝ł0.022-0.025),lowest among the building materials

- Strength: resistant to the compression

- Adhesion: excellent primerless adhesion to almost all building materials

- In-situ stability: no sagging, no shrinkage, high joint stability

- Low water permeability: due to the porous nature all PU foams can absorb up ca 20 Vol% water.

- Fire resistance: every organic material burns, same applies to the PU foams.

- Lightness

- low weight                   

- Chemical resistance - besides special dedicated chemicals, the only way to break chemical bonding of the cured foam is UV radiation

- Convenient usage and application

PU Foam is not Rock Woll, at PRETTECH engineering it is 100% welded by 2mm stainless steel cladding.
