牌号简介	D/W 211是一种由纯聚四氟乙烯（PTFE）刮削而成的薄膜，该薄膜一面用氨水（D/W 216）蚀刻，之后涂上底漆以增强弹性体和压敏粘合剂的粘合性。这种表面处理可以使聚四氟乙烯（通常表现出很差的粘附力）与其他材料结合。在某些应用中，氨酸钠腐蚀材料的强度比萘酸钠（D/W 212）腐蚀材料的强度稍高。钠蚀聚四氟乙烯的应用包括与弹性体粘合以生产层压隔膜，以及在聚四氟乙烯压敏带生产中应用压敏粘合剂。在上述所有应用中，层压或粘合应用通常通过特定于所应用材料的底漆完成。 D/W 211 is a film, skived from virgin PTFE, that has been etched on one side with sodium ammonia (D/W 216), after which a primer has been applied to enhance bonding to elastomers and pressure sensitive adhesives. This surface treatment allows PTFE, which normally exhibits very poor adhesion, to be bonded to other materials. In some applications, sodium ammonia etched materials exhibit somewhat higher strengths than those etched with sodium naphthalene (D/W 212). Applications for sodium etched PTFE include bonding to elastomers to produce laminated diaphragms, as well as the application of pressure sensitive adhesives in the production of PTFE pressure sensitive tapes. In all of the above applications, the lamination or adhesive application is usually accomplished with a primer that is specific to the material being applied.	D/W 213是一种从原始PTFE中剥离的薄膜，它已经在一侧用萘钠（D/W212）蚀刻，之后底漆被应用于增强与弹性体和压敏粘合剂的结合。这种表面处理可以使聚四氟乙烯（PTFE）与其他材料的粘合力非常差。底漆可由最终用户指定，也可由Dewal推荐用于特定用途。钠蚀聚四氟乙烯的主要应用包括与弹性体粘合以产生叠层隔膜，以及在聚四氟乙烯压敏带生产中应用压敏粘合剂。 D/W 213 is a film skived from virgin PTFE, that has been etched on one side with Sodium Naphthalene (D/W212) after which a primer has been applied to enhance bonding to elastomers and pressure sensitive adhesives. This surface treatment allows the PTFE which normally exhibits very poor adhesion to be bonded to other materials. The primer may be specified by the end user or may be recommended by DeWAL for specific applications. The primary applications for sodium etched PTFE involve bonding to elastomers to produce laminated diaphragms, as well as the applicaton of pressure sensitive adhesives in the production of PTFE pressure sensitive tapes.
