Automatic melt current ratio tester zx-4

• multi load test with up to 8 different weights

• the selection of built-in concentric weights can be used for various automatic functions, such

as loading, pressing, preloading, measuring and cleaning.

• the multi load test function of zx-4 makes it similar to rheometer. In one test run, eight different

loads can be applied to the test materials, and the MVR and MFR of the materials under different stresses can be measured and calculated.

• the operator can arbitrarily set how to run the multi load test without restriction. With zx-4, most

materials can get very repeatable test results whether the test is run in the order of decreasing the load, or in the order of increasing or decreasing the phase.

All weights are built-in, however, the selection of test weights is fully automatic.

This function makes the zx-4 test similar to the rheometer with different loads,

Furthermore, step d of ASTM d1238 and ISO 1133 flow rate ratio test can be completed.
