BEARING PROPERTIES for PACK RYT'S

 
Seal Ryt Corporation utilizes several different bearing compounds to accomplish its tasks. Most are thermoplastics, some are compression molded, others are sandwich. The following chart shows the range of values which we commonly work with:
PROPERTY ASTM UNITS RANGE
Tensile Strength D-638 PSI 9,800- 32,480
Flexural Strength D-790 PSI 11,000- 51,475
Compressive Strength D-695 PSI 22,000- 90,000
Coef/Therm/exp D-696 - 2(10(-5)F) to 3.11(10(-6)F)
Cont. Use temp UL746B Deg F 400 - 572
Melting Point DSC Deg F 505 - 644
Hardness Shore D 85 - 92

These values are not to be taken as exhaustive. The more critical and severe an application is, the more likely it is we will consider material compounds which exceed the listed parameters.
