隨著醫療器械變得更小和更緊湊，Parylene涂層的使用由于其分子水平的沉積而具有增加的價值。薄膜，無針孔Parylene保形涂層為醫療行業中的救生設備和儀器提供了最佳保護。惰性，真空沉積的Parylene具有生物相容性和生物穩定性，并具有出色的干膜潤滑性，熱穩定性，濕度，化學和隔離屏障保護。此外，Parylene已獲得FDA批準（具有aUSP XXII，VI級生物相容性等級），可安全地在體內使用。

PCT Parylene獲得USP VI級認證

 

聚對二甲苯是一種薄的真空沉積聚合物。它與傳統涂層的不同之處在于它作為薄膜在室溫下沉積在物體上，并且不使用溶劑，催化劑，增塑劑或其他特征增強添加劑。它基于稱為二對二甲苯的高純度原料，二異丙二烯是白色結晶粉末。真空和熱處理將粉末轉化為聚合物膜，其在室溫下在基板上形成。

As medical devices become smaller and more compact, theuse of Parylene coatings finds increasing value due to its molecular leveldeposition. Thin film, pinhole-free Parylene conformal coatings provide theultimate protection for life-saving devices and instruments in the medicalindustry. Inert, vacuum deposited Parylene is biocompatible and biostable andoffers excellent dry-film lubricity, thermal stability, moisture, chemical anddielectric barrier protection. Additionally, Parylene is FDA-approved (with aUSP XXII, Class VI biocompatibility rating) and is safe for use within thebody.

PCT Parylene is USP Class VI Approved

 

Parylene is a thin, vacuum-deposited polymer. It differsfrom conventional coatings in that it is deposited on objects at roomtemperature as a film, and does not use solvents, catalysts, plasticizers, orother feature-enhancing additives. It is based on a high-purity raw materialcalled di-paraxylylene, which is a white, crystalline powder. A vacuum andthermal process converts the powder to a polymer film, which is formed onsubstrates at room temperature.

Parylene Medical Coating Services
Parylene coatings protect a wide array of medical devices and componentsincluding stents, catheters, pacemakers, electrosurgical tools, epiduralprobes, mandrels, needles, and more. Medical devices used in surgicalprocedures are selectively coated with Parylene to improve their lubricity andto provide selective electrical insulation. The coating also protects and lubricateshypodermic needles and can create a biocompatible barrier on implantabledevices and prosthetic hardware. Parylene’s unique properties include preciseconformance to substrate topography, pinhole-free coverage in very thin layers,and the ability to penetrate and coat complex surfaces. Parylene film resistschemical attack from organic solvents, inorganic reagents, and acids; itadheres well to many surfaces, and offers exceptional dielectric strength.Parylene has a lubricious surface, with a coefficient of friction whichapproaches that of PTFE (Teflon).

Parylene is the ideal choice for most types of substratesincluding glass, ceramics, plastics, metals, elastomers and silicone rubber.Parylene’s optically clear coatings have the ability to conform to any shapesuch as sharp edges and points. Parylene does not promote the growth ofbiologics. Its surface is unsuitable for the proliferation of bacteria andother pathogens.
