The use of rheology in the testing of polymers is a relatively new technology, dating back to the early part of the 1960s. Today, the use of rheology testing is critical in the development of new and existing types of rubber, thermosetting plastics, and thermoplastics. The technology is also used in testing materials for quality control and in development and research of new polymers.
The use of this technology is used to measure the flow characteristics and the deformation of a material under specific pressure. The type of pressure applied through the test will measure elongation, elasticity, viscosity and can be configured to meet specific testing parameters for individual applications and samples.
Quality Testing Equipment
When choosing rheology testing equipment, it is always recommended to select the best equipment on the market. This doesn’t always mean the lowest cost equipment, but rather the equipment that offers the testing parameters, features, and functions to match your requirements. When the equipment measures and reports just what is needed the equipment is more efficient and effective, adding value to your operation.
Online or At-Line
Many rheometers are offered as either the online or the at-line option. In general, online rheometers are able to provide continuous types of process control and data recording. The at-line rheometry allows for selective sample testing as required by the company.
There are benefits to both options in rheology testing, but there are considerations with both. The online model provides continual testing but lacks the ability to test an individual sample. The at-line model is limited to testing only when technicians are present.
An option worth considering for many production or testing facilities is a rheometer that can be operated both in the online and at-line mode. These testing devices offer the quality of testing precision required with the versatility to work as needed for different testing requirements.
