NOK Low Friction Surface Treatment O-Ring "SP Treatment"

Insertion resistance reduced by 70%! The surface treatment agent reacts with the rubber surface to form an ultra-thin non-stick layer and a low-friction surface.

The "SP treatment" chemically reacts a surface treatment agent with the rubber surface to form an ultra-thin non-stick layer and a low-friction surface. The coating is colorless and transparent, resulting in a film just a few micrometers thick. This treatment maintains low friction characteristics even after thermal aging and immersion. It has been adopted in various applications, including waterproof mobile devices, in-vehicle cameras, and semiconductor manufacturing equipment, offering various benefits such as "ease of insertion and assembly" and "non-stick and low static electricity." 【Features】 ■ The surface treatment agent reacts with the rubber surface to form an ultra-thin non-stick layer and low-friction surface. ■ The coating is colorless and transparent, with a film thickness of a few micrometers. ■ There is no difference in the physical properties of the rubber material with or without SP treatment. ■ The SP treatment maintains low friction characteristics even after thermal aging and immersion. (*A matte finish treatment is required on the base O-ring surface.) *For more details, please refer to the PDF document or feel free to contact us.
