CPU vs TPU vs Rubber Coated Dumbbells
A common question we get asked is whether there is much difference between CPU Polyurethane, TPU Polyurethane and Rubber Coated dumbbells and the answer is unequivocally yes.
Polyurethane itself (or PU) is a super stable, compressed and fracture resistant material that is superior to many aspects of rubber.
CPU is Cast Polyurethane - a strong wearing, durable, temperature resistant, high strength PU that has an excellent resistance to wear and tear.
TPU is Thermoplastic Polyurethane - an affordable alternative to rubber, that offers improved durable and resistance to wear over rubber, but is inferior to CPU.
Many companies sell PU dumbbells and plates, and choose not to disclose which type of PU they use - allowing them to sell TPU products at a cheaper price than CPU, but 1RM does not. We pride ourselves on selling the highest quality PU Dumbbells possible, to ensure that our CPU Dumbbells stands the test of time for you and your gym.
So how long should you expect different types of coating to last in a commercial gym?
- Rubber Coated: 3-5 years
- TPU: 4-5 years
- CPU: 8+ years
