这种生物相容性弹性体可以被认为是橡胶、乳胶和硅材料的替代品。柔软且柔顺的Chronoprene树脂具有很高的弯曲模量,以及拉伸强度和延伸率的优异组合。一种易于成型、高流动性的材料,Chronoprene可以使用传统的挤压、注射成型和吹塑方法进行加工。其物理特性使其成为需要弹性特性的应用的最佳材料,如顺应/不顺应的气球、内窥镜和腹腔镜充气袋。Chronoprene可以在低温下加工,从而获得良好的表面光滑度和弹性。Chronoprene具有高耐磨性、耐用性和紫外线稳定性,硬度范围从5邵尔A到75邵尔A。先进的生物材料合成和制造医疗级材料,提供量身定制物理和机械特性的能力,以支持和增强您的最终产品设计。这些对医疗器械的设计和开发至关重要的机械特性可以包含广泛的物理和化学特性,同时保持核心特性,如生物耐久性和生物相容性。在大多数材料中,可以向聚合物中添加着色剂或抗菌性能(如适用)等特殊特性,以提供均匀的材料并限制二次加工步骤。此外,还可将抗辐射涂层剂纳入配方中以提供额外的产品增强,并且可含有高达40%(按重量计)的抗辐射涂层剂,从而允许不同的比例可见度选项。ASB的化学家、科学家、工程师和行业专业人员组成的专家团队,在客户项目的每一个阶段,从概念启动到全面生产,都有着广泛的二次操作范围,包括定制解决方案开发、原型涂层能力和项目管理服务。 This biocompatible elastomer may be considered as a substitute for rubber, latex and silicone materials. Soft and compliant, the ChronoPrene resins offer a high flexural modulus, as well as a superior combination of tensile strength and elongation. An easy molding, high-flow material, ChronoPrene can be processed using conventional extrusion, injection molding and blowmolding methods. Its physical properties make it an optimal material for applications requiring elastic characteristics, such as compliant/ non-compliant balloons, endoscopic and laparoscopic inflation bags. ChronoPrene can be processed at low temperatures, resulting in excellent surface smoothness and superior elasticity. ChronoPrene exhibits high abrasion resistance, durability and UV stability and is available in hardnesses ranging from 5 Shore A to 75 Shore A. AdvanSource Biomaterials synthesizes and manufactures medical grade materials offering the ability to tailor physical and mechanical characteristics to support and enhance your end product design. These mechanical characteristic's, critical to the design and development of medical devices, can incorporate a wide range of physical and chemical properties while maintaining core characteristics such as biodurability and biocompatibility. In most materials, specialized characteristics such as the addition of colorant agents or antimicrobial properties (where applicable) can be added to the polymer to provide a homogenous material and limit secondary processing steps. In addition, radiopaque agents may also be incorporated into the formula to provide additional product enhancements and may contain up to 40%, by weight, of a radiopaque agent thus allowing varied-scale visibility options. With an expanding range of secondary operations including custom solution development, prototype coating capabilities, and project management services, ASB's expert team of chemists, scientists, engineers and industry professionals assist in every stage of customers' projects, from concept initiation through full-scale manufacture. |
