高性能的热塑性塑料及热塑性弹性体流动性好,阻隔性好、透明性好、柔软性好、高强度、高耐热、烟雾少、气味小……这些高性能始终是热塑性材料工程师们努力追求的目标。
目前,随着高性能的热塑性塑料及热塑性弹性体的不断推出,这个目标正一步一步地被接近。
新型热塑性弹性体1、特种热塑性弹性体德国Wacker-Chemie(美国Wacker Silicones的子公司,它在世界上最先推出了嵌段共聚型含硅TPE)推出了Geniomer系列单相硅/尿素共聚物。
在该共聚物中,硅相作为软段(占90%)贡献弹性,尿素相作为硬段贡献强度和耐热性。
它们与TPSiV 完全不同,后者的结构为交联的硅橡胶颗粒分散在尼龙或其他工程热塑性塑料基料里。
Geniomer系列类似于TPU材料,从熔融状态冷却时能形成物理交联,再次加热时这些交联结构又可消失而成为熔融状态,因此它们具有真正的热塑性。
Geniomer系列可以采用所有的热塑性材料的加工方法。
它们按照邵式A硬度40~60的范围被分为4个等级。
其价格比热固性LSR材料稍贵一些。
Geniomer系列是非常透明的,不含催化剂、不含挥发性硅成分、填料或增塑剂。
其化学纯净度可适于医疗应用,其透明度可适于用作汽车玻璃层压片材的隔音材料。
它们具有硅材料的固有特性——抗紫外线、透气以及良好的脱模性,可以用于喷涂,也可以用作塑料材料与玻璃或金属材料的胶粘剂。
若少量(0.1% to~0.2%)加入到其他聚合物中,它们还可以用作加工助剂,以提高其他聚合物的流动性、低温柔韧性和防水性能。
Geniomer 系列产品的性能详见表1。
另一类全新的TPE是由日本Kaneka公司和德国BASF公司这两个公司推出的。
这是一种苯乙烯—异丁烯—苯乙烯三嵌段共聚物,简称为SIBS。
它是一种100%饱和聚合物,因此具有很好的热稳定性以及光稳定性。
日本Kaneka公司的这种被称为“Sibstar系列”的TPE价格为2.75$/lb ~2.95$/lb (1lb=0.4536kg)。

Conductive Elastomer Molded ProfilesConductive Elastomer Sheet Stock and Fabricated PartsPRESSURE SENSITIVE ADHESIVE (PSA) BACKINGAll standard silicone and fluorosilicone sheets of .020 inch (0.51 mm)thickness or greater are available with a thin, acrylic, electrically conductive, pressure sensitive adhesive (PSA) backing. Fluorocarbon and EPDM sheet stock are not available with PSA. While published electrical performance specifications of theconductive elastomer materials are for materials without PSA backing, there is no appreciable effect on the gasket through flange resistance or shielding effectiveness with use of PSA. Use of PSA as an attachment method for elastomer materials is meant to aid in initial assembly operations versus a long-term means of permanent attachment. Shelf life of the sheet stock with PSA is one year from date of manufacture. Sheet stock without adhesive has an indefinite shelf life. The shelf life of molded and extruded parts with PSA cannot be extended by Parker Chomerics.PSA Application : Refer to Section 1 of this guide for detailed applications guidance on PSA systems.STANDARD SHEET SIZE ORDERING PROCEDURESelect the part number from Table 6-1. The last four or five digits designate the material type. For “TA” in the part number, select the desired thickness (“T” code) and adhesive option (“A” code) from the Thickness and Adhesive Option Specification guide following the table. For custom sizes or thicknesses, part numbers will be assigned by Parker Chomerics.CUSTOM DIE-CUT PARTSCustom parts can be die-cut by Parker Chomerics or its Authorized Fabricators from any standard sheet stock. Please provide a sketch or drawing to Parker Chomerics Applications Engineering. It will be reviewed for appropriate design criteria, such as wall thickness and feature size and location. Parker Chomerics will assign a custom part number for custom die-cut parts. The custom part number will be 19-11-ZZZZZ-XXXXXwhere ZZZZZ is a sequential manufacturing drawing number(assigned by Parker Chomerics), and XXXXX is the material designation (1285, L6303, etc.).GENERAL TOLERANCESTable 6-2 provides general tolerances for flat die-cut conductive elastomer gaskets. It is important to note that all flat die-cut and molded gaskets are subject to variation in the unrestrained condition. The use of inspection fixtures to verify conformance of finished parts is common andrecommended where appropriate. Also note that “Overall Dimensions” for flat die-cut gaskets include any feature-to-feature dimensions (e.g., edge-to-edge, edge-to-hole, hole-to-hole).SHEET STOCKParker Chomerics electrically conductive elastomer materials are available in sheet form. We are able to meet most design requirements with the standard sizes and thicknesses shown in T able 6-1.Table 6-13 = Available NA = Not Available*TA refers to thickness and adhesive options.For sizes other than those shown, change 5th through 8th digits in Part Number to reflect desired up to max size (e.g., 0415 is a 4 in x 15 in size).MOLDEDTable 6-1 continued3 = Available NA = Not Available*TA refers to thickness and adhesive options.For sizes other than those shown, change 5th through 8th digits in Part Number to reflect desired up to max size (e.g., 0415 is a 4 in x 15 in size).Table 6-1continuedTable 6-23 = AvailableNA = Not Available*TA refers to thickness and adhesive options.For sizes other than those shown, change 5th through 8th digits in Part Number to reflect desired up to max size (e.g., 0415 is a 4 in x 15 in size).Thickness and Adhesive Option SpecificationMOLDED。
