Foaming Process

Strength and purity of T-Tubes® clean environment insulation come from the inherent robust nature of Kynar®PVDF resin and the unique process used to turn it into foam.

A unique foaming process converts Kynar®PVDF resin to foam by simply introducing nitrogen into it. There are no chemical blowing agents, toxic or non-toxic, that may reduce the efficiency or purity of the foam. Since nitrogen is an inert gas, the resulting foam is as pure and robust as the resin that is used.
