Deformation rubber mainly used in building construction roofing, interior building floor, parking lot pavement slot devices, such as buildings, the building due to expansion and contraction caused by temperature changes and deformation caused by unequal floor building height different settlement and sudden various modifications have a significant role in the displacement of earthquakes. Because buildings usually require coordination and overall appearance, so building deformation joint rubber seals often have different colors. Thermoplastic EPDM (santoprene) has excellent coloring, good color stability, as well as the excellent overall performance, making it the first choice of various types of plastic materials.
