polyurethane sealant
High elasticity polyurethane sealant, with a fracture elongation rate of 300% -800%, displacement capacity of ± 25% – ± 50%, and elastic recovery rate of ≥ 70%, achieves “high elasticity+high strength+weather resistance” through the separation of soft and hard segments. It is the preferred elastic sealing material for building expansion joints, automobiles, road surfaces, and […]
