PolyBlend是一类非常柔软的芳香族聚氨酯弹性合金,在许多应用中可作为天然橡胶或乳胶的替代品。这些聚合物具有独特的特性,如低弯曲模量、中等拉伸强度和高延伸率,此外,由于其具有优越的熔融强度和化学完整性,因此具有较高的拉伸比。PolyBlend可以在传统的挤压或注射成型设备上加工,硬度范围从45邵尔A到80邵尔A不等。AdvanceSource BiomeMaterials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,在保持诸如生物耐久性和生物相容性等核心特性的同时,可以包含广泛的物理和化学特性。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。 PolyBlend is a family of exceptionally soft, aromatic polyurethane elastomeric alloys, which can be used as a substitute for natural rubber or latex in many applications. These polymers encompass unique characteristics such as low flexural modulus, moderate tensile strength, and high elongation, in addition to allowing for a high draw-down ratio due to its superior melt strength and chemical integrity. PolyBlend can be processed on conventional extrusion or injection molding equipment and is available in hardnesses ranging from 45 Shore A to 80 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. |
