Random Oriented Fiber Structural Bearing Pad
Hanna Rubber Company produces Masticated (recycled) Rubber Load Bearing Pads, which are used in many construction applications such as precast and prestressed concrete bridges, building and structural steel bearing applications, as well as machinery, equipment foundation, railway tie pads, and shock and vibration isolation. Hanna Rubber’s Masticated Load Bearing Pads are made using a controlled blend of recycled rubbers that are fully cured with synthetic fibers that creates internal stiffening. With the synthetic fibers added to the Masticated Load Bearing Pads they are able convey improved tensile and compressive strength, stiffness, tear resistance, durability, and superior ozone and weather resistance.
