Within the scope of the Kastas R&D Department Material Development Division, raw material and product development activities that are two of the most important factors that affect the performance of the seal in line, with a design that makes a difference in different applications. 

Polyurethane material is commonly used in fluid power systems due to its advantages, such as wear resistance, tensile strength and tear resistance, which enables durable solutions in both hydraulic and pneumatic systems.

Standard polyurethane materials have superior mechanical properties compared with elastomers. However, they also have disadvantages, such as low resistance to different environmental conditions, in particular to fireproof hydraulic fluids and air, and high compression set value at low hardness.  

Kastas developed a new polyurethane material, PU8502, for increasing expectations for high performance for the pneumatic systems and applications requiring material usage with low hardness.
