• Casting polyurethane elastomer (CPU), is the most widely used polyurethane elastomer, knowm as the “king of anti-friction” (natural rubber 5-10 times); high mechanical strength (natural 2-3 times), the tensile strength, elongation, tear degree machanical properties are much better than the rubber material, and has a wide range of hardness, are available in a wide range of hardness to maintain a high elasticity, high hardness andhas high elasticity, CPU oil resistance, aging resistance performance is better than the nature rubber and other synthetic rubber, radiation resistant performance, low temperature resistant performance, high temperature resistant, long time continuous working temperature range is generally 80-90 degrees, and short time using the temperature up to 120 degrees. • Unlimited Versatility: A good bumper plate set is the centerpiece for modern HIIT training.
