The Butylver TPS is a solvent-free, poly-isobutylene spacer capable of forming chemical bonds with glass surfaces. Designed to seamlessly integrate with all TPS applicators, this thermoplastic spacer streamlines the production process of structural and standard insulating glass units, elevating warm-edge performance and enabling high-level industrial automation. Crafted from a single component poly-isobutylene base with integrated desiccants, Butylver TPS ensures precise adhesion, minimal permeability and exceptional stability—up to 20-millimeter cavity—for contemporary IG applications.
