Overview
Instron's CEAST Modular Melt Flow Multiple Weight Tester is a major development in melt flow testing. A single test can be performed with one, two or three weights applied on the same sample load, in an increasing or decreasing sequence.
The output results include the shear sensitivity (or flow rate ratio), one of the first data for wider rheological investigation, and the first low shear rate points of the rheological curve of the sample.
Features
- Performs tests according to ISO 1133 and ASTM D1238 Procedures A, B, C and D
- Single weight tests or multiple weight tests can be used to perform a test sequence using one, two or three weights
- Pre-installed cycles according to standards recommended procedures, and the ability to configure a full range of customized parameters based on an individual's requirements
- High accuracy encoder and numerically controlled motorized weight lifter for a precise weight positioning
- Optional unique load cell feature to apply an exact force, up to a maximum of 750 N, on the material during compacting to increase result repeatability
- Reduced test cycle time by automatically purging after test
- Optimum test conditions for high flow rate polymers
