Raw Material
- ASTM D1646 – Mooney viscosity
- ASTM D5668 – Volatile content
- ASTM 5667 – Ash Content
- ASTM D 297 – SiO2 Content, Moisture content, Purity
Standard Test Methods for Rubber Viscosity, Stress Relaxation, and Pre-Vulcanization characteristics.
Standard Test Methods for determination of Moisture and other volatile matter content in Synthetic Rubber.
Standard Test Method for the determination of ash content (Total and Water Soluble) in Synthetic Rubber.
These test methods cover the qualitative and quantitative analyses of the composition of natural and synthetic crude rubbers. These methods are divided into general and specific test methods. General test methods shall be performed to determine the amount and type of some or all of the major constituents of a rubber product, and shall include determination of rubber polymer content by the indirect method, determination of density, and extract, sulfur, fillers, and ash analyses. Specific test methods, on the other hand, shall be performed to determine specific rubber polymers present in a rubber product such as crude, unvulcanized, reclaimed, and vulcanized rubbers
- ASTM D1298- Specific gravity
- ASTM D92 – Flash point
Standard Test Method for determination of Density, Relative Density, or API Gravity of Oils by Hydrometer Method.
This test method describes the determination of the flash point and fire point of petroleum products by a manual Cleveland open cup apparatus or an automated Cleveland open cup apparatus.
- ASTM D4574 – Ash content
- ASTM D4571 – Volatile content
- ASTM D1519 – Melting point
- ASTM D 1514 – Sieve residue
- ASTM D974 – Acid number
These test methods cover the determination of ash content of Rubber Compounding Materials – Chemicals.
These test methods cover the determination of the loss of Volatile materials in various Rubber Chemicals based on the mass loss upon heating at 70 C.
These test methods cover the determination of the melting range of commercial rubber processing chemicals either by use of capillary melting point tubes or by differential scanning calorimetry (DSC).
This test method covers the determination of the water wash sieve residue in regular untreated carbon blacks. It may not be applicable to oil-treated carbon blacks because the oil would prevent proper wetting of the black by water.
This test method covers the determination of acidic or basic constituents in petroleum products and lubricants soluble or nearly soluble in mixtures of toluene and isopropyl alcohol.
