MIL-P-5425 Cast Acrylic Sheet by K-mac Plastics  Cast Acrylic: Similar to Plexiglas, this acrylic provides outstanding optical clarity even at high thickness. Sheets are thermally pre-shrunk and meet military specification MIL-P-5425   GMS Acrylic Cast Sheet Order Cast Acrylic Sheet Online-Click Here Technical Data Sheet   GMS Available Sizes and Prices   ACRYLITE® GMS ACRYLIC SHEET   DESCRIPTION ACRYLITE GMS Aerospace Acrylic Sheet is manufactured to meet or exceed the requirements of military specification MIL P-5425E.  ACRYLITE GMS sheet is manufactured in equipment that is reserved for aerospace acrylic products, is subjected to a preshrunk cycle, and undergoes an optical inspection which is among the most critical in the industry.   FABRICATION Any fabrication technique that is appropriate for standard cell cast acrylics will be equally appropriate for ACRYLITE GMS sheet. When drape forming ACRYLITE GMS sheet, excellent results can be achieved if the sheet is heated evenly between 300°F and 320°F.  For pressure forming or vacuum forming operations temperatures of 340°F to 380°F are recommended   APPLICATIONS ACRYLITE GMS sheet is used in aerospace transparent enclosures in monolithic or laminated form.  Current applications for ACRYLITE GMS sheet include instrument panels, wingtip lenses, dust covers, helicopter bubbles and aircraft canopies.   PROPERTIES The table below shows typical values for 0.250 inch thick ACRYLITE GMS sheet.  Some values will change with thickness.   TEST                                      METHOD                              TYPICAL VALUES* ANGULAR DEVIATION                    ASTM D-637                                        <3 minutes TENSILE STRENGTH                         ASTM D-638                                        11,000 psi ELONGATION                                     ASTM D-638                                        5.7% FLAMMABILITY                                ASTM D-635                                        1.25 inch/min DEFLECTION TEMPERATURE        ASTM D-648                                        115°C  (264 psi) INTERNAL STRAIN                           MIL P-5425E                                         <1% RESISTANCE TO WEATHERING     MIL P-5425E and                  (10 days accelerated)          ASTM D-1003                                      Before                   After       LIGHT TRANSMISSION                                                                    92.6%                     92.3% HAZE                                                                                                     0.40%                     0.40% SPECIFIC GRAVITY                            ASTM D-792                                        1.19 THERMAL EXPANSION                   ASTM D-696                                        0.000061 in/in-°C WATER ABSORPTION (24 hr)         ASTM D-570                                        0.33% * Not for specification purposes   ACRYLITE GMS Sheet Thickness Tolerances:       Class A Min/Max Sheet up to and including 36" x 60" 40” x 50” Class B Min/Max Sheet larger than Class A including 48”x48”  53”x80” 60"x72" Class C Min/Max Sheet larger than Class B including 67”x102” 72”x96” in mm       0.060 1.5 0.048/0.072 0.040/0.080 0.040/0.080 0.080 2.0 0.068/0.092 0.060/0.100 0.060/0.100 0.100 2.5 0.088/0.112 0.080/0.120 0.080/0.120 0.125 3.2 0.110/0.140 0.105/0.145 0.095/0.155 0.150 3.8 0.133/0.167 0.130/0.170 0.120/0.180 0.187 4.7 0.167/0.207 0.164/0.210 0.157/0.217 0.220 5.6 0.197/0.243 0.195/0.245 0.190/0.250 0.250 6.4 0.225/0.275 0.220/0.280 0.215/0.285 0.280 7.1 0.250/0.310 0.245/0.315 0.240/0.320 0.312 7.9 0.282/0.342 0.277/0.347 0.272/0.352 0.375 9.5 0.340/0.410 0.335/0.415 0.330/0.420 0.417 10.6 0.377/0.457 0.372/0.462 0.372/0.462 0.500 12.7 0.460/0.540 0.455/0.545 0.450/0.550   Note:  Shipping charges will apply to all orders, and will vary depending on Customer ship to location, pricing does not reflect shipping charges
