Possibleirritation of the respiratory system can occur causing a variety of symptoms such as dryness of the throat, tightness of the chest, and shortness of breath. May cause central nervous system depression characterized by the followingprogressive steps: headache, dizziness, staggering gait, confusion, unconsciousness or coma. Significantoverexposure to n-butyl glycidyl ether by the inhalation route is unlikely under most ambient conditions due to its low volatility. However, vapors, aerosols, and mists may be formed during some applications such as heating orapplications of uncured material on large surface areas. Harmful if absorbed through skin. May be harmful ifswallowed. Ingestion is not an expected route of entry in industrial or commercial uses.Chronic: IARC has designated carbon black as Group 2B - inadequate evidence for carcinogenicity in humans, but sufficient evidence in experimental animals. In 2006 IARC reaffirmed its 1995 finding that there is "inadequateevidence" from human health studies to assess whether carbon black causes cancer in humans. Further,epidemiological evidence from well-conducted investigations has shown no causative link between carbon black exposure and the risk of malignant or non-malignant respiratory disease in humans.3.

德国拜耳TeXin-RXT50D医疗级TPUProduct Information TEXIN? RxT50DThermoplastic PolyurethaneAromatic Polyether-Based GradeDescription and ApplicationsTexin RxT50D resin is an aromatic polyether-based thermoplastic polyurethane. It can be processed by injection molding, extrusion or blow molding. Texin RxT50D offers outstanding abrasion resistance, impact strength, toughness and flexibility. It also exhibits excellent hydrolytic stability.Typical medical applications include anesthetic connectors, catheters, flexible tubing, film, seals and gaskets and extruded profiles.Medical ApplicationsBiocompatibility: Texin RxT50D resin meets the requirements of the FDA-modified ISO 10993, Part 1“Biological Evaluation of Medical Devices” tests with human tissue contact time of 30 days or less. Only products that meet these requirements may be considered candidates for applications requiring biocompatibility.Regrind must not be used in medical applications requiring biocompatibility.Manufacturer’s Responsibility: It is the responsibil-ity of the medical device, biological product or pharmaceutical manufacturer (“Manufacturer”) to determine the suitability of all component parts and raw materials, including Texin RxT50D resin, used in its final product in order to ensure safety and compli-ance with FDA requirements. This determination must include, as applicable, testing for suitability as an implant device and suitability as to contact with and/or storage of human tissueand liquids including, without limitation, medication, blood or other bodily fluids. Under no circumstances may Texin RxT50D resin be used in any cosmetic, reconstructive or reproductive implant applications. Nor may Texin RxT50D resin be used in any other bodily implant applications or any applications involving contact with or storage of human tissue, blood or other bodily fluids for greater than 30 days, based on FDA-modified ISO 10993, Part 1 “Biological Evaluation of Medical Devices” tests. Furthermore, for aromatic grades of Texin resins, such longer-term uses are not permissible because possible hydrolysis of solid polyurethane may produce aromatic amines, such as methylene dianiline (MDA).The suitability of a Bayer product in a given end-use environment is dependent upon various conditions including, without limitation, chemical compatibility, temperature, part design, sterilization method, re-sidual stresses and external loads. It is the responsi-bility of the Manufacturer to evaluate its final product under actual end-use requirements and to adequately advise and warn purchasers and users thereof.Single-use medical devices made from a Bayer product are not suitable for multiple uses. If the medical device is designed for multiple uses, it is the responsibility of the Manufacturer to determine the appropriate number of permissible uses by evaluating the device under actual sterilization and end-use conditions and to adequately advise and warn purchasers and users thereof.Sterilization: Parts molded or extruded from Texin RxT50D resin are sterilizable using ethylene oxide, radiation or dry heat. Parts made of Texin resins must not be sterilized using steam autoclaving or boiling water techniques. Furthermore, thesesteril-ization methods must not be used with aromatic grades of Texin resin because possible hydrolysis of solid polyurethane may produce aromatic amines, such as methylene dianiline (MDA).Page 1 of 3— Document contains important information and must be read in its entirety.The sterilization method and the number of steriliza-tion cycles a medical device made from TexinRxT50D resin can withstand will vary depending upon type/grade of product, part design, processing parameters, sterilization temperature and chemical environment. Therefore, the Manufacturer must evaluate each device to determine the sterilization method and the number of permissible sterilization cycles appropriate for actual end-use requirements and must adequately advise and warn purchasers and users thereof.Storage, Drying and Regrind UsageTexin thermoplastic polyurethane resins are hygro-scopic and will absorb ambient moisture. The resins should remain in their sealed containers and stored in a dry area. Storage temperatures should not exceed 86°F (30°C). Unused resin from opened containers, or reground material that is not to be used immedi-ately should also be stored in sealed containers under cool and dry conditions.Prior to processing, Texin RxT50D resin must be thoroughly dried for a minimum of 2 hours in a desiccant dehumidifying hopper dryer to a moisture content of less than 0.03%. Hopper inlet air tem-perature should be 200-220°F (93-104°C), the inlet air dew point should be 0°F (-20°C) or lower.Injection Molding, Extrusion and Blow Molding Conditions Typical starting conditions for injection molding, extrusion, and blow molding are noted below. It is recommended that initialprocessing is done at the lower end of the suggested temperature ranges and increased as necessary. Actual processing condi-tions will depend on machine size, mold design, material residence time, shot size, part geometry, etc.Typical Injection Molding ConditionsBarrel Temperatures:Rear…………………….........…385o-405oF (196o-207oC)Mid dle…………….........……… 390o-410oF (199o-210oC)Front……………….........…… 390o-410oF (199o-210oC)Nozzle…………………........ 395o-415oF (202o-213oC) Melt Temperature………….......…395o-415oF (202o-213oC) Mold Temperature………….......…… 60o-100oF (16o-38oC) Injection Press ure………..........………….6,000-15,000 psiHold Pressure………........….60-80% of Injection Pressure Back Pressure……….......……………………..800 psi max.

二：绳扣是什么材料，包括弹簧过检针、和其它做对比好在什么地方。

□有塑料PP, ABS, PA等。

□过检针弹簧，合乎欧美日的高标准安全检测规范。

□优势：采用环保材料；合乎人体工学的设计；精细的工艺外观。

三：金属配件材料，和其它对比好好在什么地方。

□锌合金压铸成形加上无镍电镀(合乎环保规范)，用于复杂曲面构造零件，呈现精致质感以增益商品价值。

□黄铜合金钣材冲压成形加上无镍电镀(合乎环保规范)，用于金属弹簧扣或裤钩等，具备古典金属轻盈质感可经久耐用。

□金属合金材料不仅物性稳定而且没有塑料件的老化问题，确保完全的功能。

附件是拜耳的悟性表，重要部分要我们翻译成中文。

□TPU（热塑性聚氨酯弹性体）是新兴的塑料品种，由于TPU具有良好的加工性、耐候性、环保性，被广泛应用于鞋材、管材、薄膜、滚轮、电缆电线等相关行业。

聚氨酯热塑性弹性体又称热塑性聚氨酯橡胶，简称TPU，是一种(AB)n型嵌段线性聚合物，A为高分子量(1000-6000)的聚酯或聚醚，B为含2-12直链碳原子的二醇，AB链段间化学结构是用二异氰酸酯，通常是MDI连接。

一般的结构式为见图。

热塑性聚氨酯橡胶靠分子间氢键交联或大分子链间轻度交联，随着温度的升高或降低，这两种交联结构具有可逆性。

在熔融状态或溶液状态分子间力减弱，而冷却或溶剂挥发之后又有强的分子间力连接在一起，恢复原有固体的性能。

聚氨酯热塑性弹性体有聚酯型和聚醚型两类，白色无规则球状或柱状颗粒，相对密度1〃10-1〃25，聚醚型相对密度比聚酯型小。
