Where heavier spheres are required Pepson encapsulate a range of metal inserts in the polyurethane. These include aluminium, cast iron and hollow aluminium and cast iron inserts. Each insert is shot blasted, cleaned and bond sprayed to ensure a homogenous polyurethane/ metal sphere resistant to splitting and separation.

Hardness: shore A 10- Shore D 85 |
| 2 |
High strength Under rubber hardness, its strength and loading capacity is much better than rubber. Under high hardness, its impact resistance and flexibility are much better than plastic. |
| 3 |
Excellent anti-abrasion performance it is about 3-5 times of rubber. |
| 4 |
Oil resistance Polyurethane is a strong polar polymer compound.Its affinity with non-polar oil is very slim, so there is almost no erosion in fuel oil and mechanical oil. |
| 5 |
Superior anti-aging properties, good resistance to oxygen and ozone
|
| 6 |
PU Roller is with good physical properties, it won't harden or age under long term usage, and it maintains good tear resistance, resilience and anti-abrasion performance. It is easy to store for a long time. Its anti-abrasion performance is 3-5 times of rubber. Its life span is more than 3 times compared with rubber roller. |
| 7 |
It is with excellent mechanical reprocessing properties. |
| 8 |
The metal part strongly bonds with PU. It won't break out. It could also be oil resistance, water-proof or anti-solvent |
