Coated-core cleaner blades
摘要:
A coated-core cleaner blade has a core comprising a first material and a coating surrounding the core. The coating comprises a second material that is different than the first material. Further, the core (first material) is rigid compared to the coating (second material). Therefore, the first material has a first flexibility that is much less than a second flexibility of the second material.
