Additionally, the company has more than 40 years of applications experience in the medical device, electronics, automotive, aerospace and defense industries. パリレンは、Michael Mojzesz Szwarcにより1940年代後半に初めて発見されました。. Parylene is a viable coating option for medical devices primarily because of its biocompatibility and biostability. 1200. Parylene (poly paraxylylene) is a generic name for polymers that belong to a unique chemical family and are used as conformal coatings in protective applications. Coating Application. The majority of parylene product runs -- wherein the dimer is polymerized and applied as conformal coating to the selected substrate -- require about a pound of raw parylene dimer. Parylene is unique in being created directly on the surface at room temperature. Is parylene a hydrophobic coating? Yes, parylene coating has hydrophobic properties repelling water and moisture. Form Punch for Aluminium. Parylene C is a promising surface coating for bioresorbable Mg alloy stents for clinical applications.
