POLYCAST SAR combines the physical characteristics of cast acrylic sheet with an abrasion resistant, cleanable surface. POLYCAST SAR gets its super hard, glass-like surface from a coating of cross-linked polysilicate resin. In addition to outstanding abrasion resistance, POLYCAST SAR offers enhanced chemical resistance from standard acrylic sheet. POLYCAST SAR has limited formability, information on forming techniques is available upon request. POLYCAST SAR is available | SHEETS: | 125 - .250 (standard). .060 -1.250 (custom) thick | | SIZE: | 48" x 96" to 72" x 108" (standard range) | | COLORS: | Clear is standard. All Lucite SAR II colors are custom products. | | Typical Physical Problems | Test Method | POLOYCAST SAR | Acrylic Sheets | Plate Glass | | Optical | | | | | | Luminous Transmittance (%) | ASTM D1003 | 93 | 92 | 89 | | Haze (%) | ASTM D1003 | 0.5 | 0.6 | 0.9 | | Index of Retrofaction | ASTM D542 | 1.43 | 1.49 | 1.5 | | Abrasion Resistance (Reported as percent increase in percent haze) | Steel Wool Rotary Test 12psi 24psi | | | | | | Taber Abrasion Test 500g. each wheel, 100rev 500g. each wheel, 100rev | ASTM D1044 ANSI Z26.1-1983 | 0.44 7.6 | 14 - | 0 0.7 | | Mar Resistance Test, 100gSiC | ASTM D673 | 2.3 | 29 | 3.3 | | Impact Resistance (all data refer to 0.025 in thickness) | | Notched Izod, ft.lb./in. | ASTM D256 | 0.3 | 0.3 | 0.1 | | Falling Steel Ball, 0.5 lb breakage drop height (ft.) | | 18 | 18 | 2.5 |    |
