Elastic Rubber Polyurethane Hollow Rod Spring Bar 20-40mm OD 8mm Bore 500mm Long Yellow for Industrial Use

• 【Durability】Polyurethane elastomers are characterized by high strength, high elasticity, small deformation and good stretching force.
• 【Tear&Abrasion Resistant】Polyurethane provides better tear and abrasion resistance and can be more readily bonded to another material.
• 【PU Material】Using polyurethane as die material can greatly shorten the time and cost of making die.
• 【Lightweight】Low weight, machinability, corrosion resistance, exceptional impact resistance, typically good thermal and electrical insulating properties.
• 【Applications】Used for all kinds of machinery acting as a buffer or shock absorber, a ideal die spring.
