Elastomeric Black EPDM Rubber Seal Strip for Concrete Floor / Expansion Joint. Innovative Multi-Cavity Design: The internal triangular/cellular structure maximizes flexibility and compression resilience. Reinforced Rib Exterior for Structural Integrity: The external ribbed profile ensures positive locking into grooves or mating surfaces, preventing extrusion and ensuring a consistent, leak-proof seal. Superior Durability & Weather Resistance: Constructed from high-grade EPDM, the seal resists UV radiation, ozone, acid/alkali corrosion, and extreme temperatures. Custom Material & Dimension Flexibility: Available in different rubber durometers (Shore A 40-90) and materials (NBR, Silicone, CR) to suit specific chemical resistance, temperature, cost requirement.
