open-cell polyurethane foam filling | more flexible than standard PE back filling | packaged per 50 pieces
This filling foam is made from open-cell polyurethane foam. The open structure allows air to escape easily during the application of sealant, preventing blistering. The material is more flexible than standard PE backing and adapts better to uneven surfaces or variations in joint depth. This ensures reliable adhesion and a durable result. Packaged per 50 pieces.
Suitable for placement in open gaps to keep them closed. For more information, please contact our specialists.
