I need PU belts now. This part is 80 shore A polyurethane or equivalent. It needs to be reinforced with minimum tear strength of approximately 500 lbs. We will need 5000 pieces this year within the next 6 months and approximately 10000 each year to follow. This belt is human powered so the lighter the better. If you can foam the polyurethane and maintain the same strength and hardness, that would be good. We are open to suggestions. Contact us soon.
