Product Description Soudal Flexifoam Gun is a one-component, self-expanding, ready to use polyurethane foam. It is fitted with a plastic adaptor head for use with a foam applicator gun. Propellants used are harmless to the ozone layer and have do not contribute to the green house effect. The product has minimal expansion after application (less than 50%) and is therefore very economical to use. Flexifoam is very elastic and has a very high acoustic rating value. Elastic Recovery ( ISO 1856) is up to 90% if the foam is compressed by 75%. Traditional PU-foam does not have any recovery if the compression is higher than 10%. Elongation at break is three times that of traditional foam. The maximum elongation before breaking (DIN 18540) is about 45% compared to 15% for traditional PU-foam. Thanks to these flexibility properties, the foam will maintain its general characteristics much better. Joint movements through the years will cause a traditional PU-foam to break and lose some of the following properties: Flexifoam follows the movements of the joint and will keep its insulating properties over the years. This is certainly a necessity for larger windows in PVC or aluminium, especially in smaller joints (e.g. 2 to 3 cm width). The maximum movement allowed for traditional foam before breaking is only 2 mm compression or 3 mm elongation. Moreover, after several years the maximum elongation and compression will reduce to possibly 50%. That's why Soudal created Flexifoam which has high movement capability as well as stress resistance in time. Box Contains 1x 750 ml Flexi-Foam Flexible Expanding Foam
