Analysis and prevention of yellowing of PU steel wire hose
Yellowing of PU steel wire hose caused by antioxidant effect.
Now many PU steel wire hoses mainly choose TDI or MDI as raw materials. These substances undergo complex chemical reactions under the action of light, heat, oxygen, and especially ultraviolet rays to generate chromophores. The resulting PU steel wire hose is easy to yellow and cannot maintain high transparency for a long time.
Ultraviolet rays can also cause PU steel wire hoses to yellow
When the PU steel wire hose is produced and needs to be placed for a period of time. It should be placed in a dry area with dark light. In particular, avoid direct sunlight.
Solutions to prevent yellowing of PU steel wire hoses
In the area where PU steel wire hoses are produced and stored, minimize the oxygen content (inert gas can be filled). It is also possible to add antioxidants, ultraviolet absorbers, etc. to effectively delay the yellowing of PU steel wire hoses.
Of course, yellowing does not affect the performance of PU steel wire hoses, but only affects the visual experience. Orientflex uses high-quality raw materials to effectively delay the yellowing of PU steel wire hoses.
