Petrochemical products such as greases, waxes, bitumen, asphalt, pitch and tar gradually soften as the temperature rises and melt over a relatively large temperature interval. Generally, the dropping point or softening point test is an easily accessible parameter used to characterize the thermal behavior and quality of these types of samples.
We compiled the answers to the most asked questions about dropping point and softening point in the petrochemical industry in a simple document, including tips for correct sample preparation and measurement and what the relevant standards in the industry are.
Discover the answers to the most common questions:
- How can I measure the dropping point of lubricants and greases?
- How can I measure the softening point of bitumen and pitch?
- What are the advantages of automatic dropping point determination?
- What is the difference between the cup-and-ball and ring-and-ball methods for softening point determination?
- Which standards regulate dropping and softening point measurements?
