Durometers are described in the American Society for Testing and Material specification ASTM D2240, which is the recognized specification for the instrument and testing procedures.There are a number of brands of durometer measuring devices, all of which must conform to the same ASTM specifications to be certified calibrated for use. Sometimes a durometer scale of measurement may be referred to by its’ brand name. The “A” scale (or type A) is the most commonly referenced form of measurement for neoprene hardness. At Kellett Enterprises, we have pads in 2 shore "A" durometer catagories:. • Shore "A" Durometer of 70 +/-. This pad is used for heavy equipment such as weaving machines, granulators, hydraulic presses, rock crushers etc. • Shore "A" Durometer 50 +/-. This pad, being more pliable, is better suited for equipment such as air conditioners both residential and commercial, generators, computer & lab equipment, etc.   BACK TO TOP     In Common Characteristics of 50 and 70 Durometer   LP-13 Shake Absorber®  Vibration Isolation pads Thickness: 3/8” = 9.52 mm 3/4” = 19.05 mm Tensile Strength: 1100 UV Resistance: Excellent Temperature Range Fahrenheit /Celsius: -40 degrees to 200 Degrees F -40 C to 93.33 C Oil /Abrasion /Flame Resistance: Good I 50 Durometer Characteristics Thickness: 3/8” = 9.52 mm 3/4” = 19.05 mm Shore A Durometer: (Neoprene): 50 (+/-? 10) Max Load: 100 PSI @ 10hz Deflection (Displacement) @ 10 HZ: @25 PSI = 0.42 mm @50 PSI = 0.80 mm @75 PSI = 1.40 mm @100 PSI = 1.96 mm @25 PSI = 0.44 mm @50 PSI = 0.96 mm @75 PSI = 1.92 mm @100 PSI = 2.99 mm Damping Coefficient  @ Max Load & 10 HZ: 48.84 N-Sec/mm 24.46 N-Sec/mm Co efficient of Friction -Static: .999u .831u - Dynamic: .988u .759u Water Absorption by Weight: < 3 % < 5 % 70 Durometer Characteristics Thickness: 3/8” = 9.52 mm 3/4” = 19.05 mm Shore A Durometer: (Neoprene): 70 (+/- 10) Max Load: 400 PSI @ 10hz Deflection (Displacement) @ 10 HZ: @100 PSI = 0.34 mm @200 PSI = 0.62 mm @300 PSI = 1.14 mm @400 PSI = 1.64 mm @100 PSI = 0.51 mm @200 PSI = 1.48 mm @300 PSI = 3.04 mm @375 PSI = 3.89 mm Damping Coefficient @ Max Load & 10 HZ: 104.41 N-Sec/mm 95.81 N-Sec/mm Co efficient of Friction -Static: .542u .963u - Dynamic: .515u .886u Water Absorption by Weight: < 2 % < 4 %   BACK TO TOP
