Polytite N


Polytite N at Sunshine IndustrialPolytite N is our premium bridge expansion joint sealer. It is pre compressed for easier handling.

It is a high-density open micro cell polyurethane foam impregnated with a hydrophobic polymer sealing compound. Polytite N works under its own constant internal pressure to provide a permanent watertite seal eliminating costly water damage as well as allowing for a greater degree of joint movement.

Once Polytite N is installed the material expands depending on the temperature adapting to the width of the joint as well as irregularities.
