Reported values are not independent test results. Original units and table wording are preserved. Extracted TDS rows can depend on the grade, component and source table headings; use the linked page to verify that context. Test methods, sample preparation and cure schedules may differ; consult the original TDS before making a performance comparison.

Selection & processing checks

Distinguish rigid casting plastics, elastomeric rubbers and foams. Their density, hardness scales and processing requirements are not interchangeable.

  • Is this a solid material or an expanding foam?
  • Which hardness scale and cure conditions are reported?
  • What moisture-control and preparation steps does the manufacturer require?
  • Confirm the complete product designation, including any hardener, color or formulation suffix.
  • Read the current SDS for handling, protective equipment, storage and disposal information.

The reported weight ratio for this record is 115A:100B. A weight ratio must not be used as a volume ratio without the appropriate density information.

Missing properties are not estimated. Similar values or shared application labels do not establish a drop-in replacement.
