派瑞林用于医疗器械的讨论

伴随着医疗设备越来越更小和更紧密，Parylene镀层的应用因为其分子结构能力的沉淀而具备提升的使用价值。塑料薄膜，无针眼Parylene保形镀层为医药行业中的救生设备和仪器设备给予了最好维护。可塑性，真空泵堆积的Parylene具备相溶性和生物体可靠性，并具备优异的湿膜润湿性，耐热性，环境湿度，有机化学和防护天然屏障维护。除此之外，Parylene已得到FDA准许（具备aUSP XXII，VI级相溶性级别），可安全性地在身体内应用。

PCT Parylene得到USP VI级验证

聚对二甲苯是一种薄的真空泵堆积高聚物。它与传统式镀层的不同点取决于它做为塑料薄膜在常温下堆积在物件上，而且不应用有机溶剂，金属催化剂，增粘剂或别的特点提高添加物。它根据称之为二对二甲苯的高纯原材料，二异丙二烯是乳白色结晶体粉末状。真空泵和热处理工艺将粉末状转换为高聚物膜，其在室内温度下到基材上产生。

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.
