Inquiry (采购产品): silicone rubber sheet I have to select a grade for A-A-59588 silicone rubber sheet. From the specification, I selected class 3B as most appropriate for our space flight hardware launch restraint application. The grades/durometers to choose from are: 30, 50, 60 70 and 80. Can you please send me a small sample in each of these 5 grades so I can determine which one to use? I would really appreciate it. Thank you very much. - Sonia **** Hidden Message ***** Sonia James TX 77058 USA Company: Jacobs Sverdrup ESCG Title: Engineer E-mail: sonia.l.ried1@jsc.nasa.gov **** Hidden Message ***** sonia.l.ried1@jsc.nasa.gov
