Standard operating temperature Range: -50 OC to +80 OC
Hardness Range: 40 – 90 Shore A
Features:
- General purpose rubber
- Good physical properties, when properly compounded.
- Poor chemical, oil, solvent resistance properties
- Poor heat resistance
- Poor weather, ozone, UV resistance
Applications:
- General purpose mouldings, extrusions, seals, gaskets, hoses, profiles, roll, belts, bearings, lining, rubberized fabric, shoe soling etc.
