Reverse pressure test chamber

Polymers tend to be processed under high pressure. Taking the viscosity as the processing reference process data, the processing pressure has considerable fluctuations. In this way, the viscosity changes due to pressure changes, which can not be ignored.

This phenomenon can not be analyzed with the previous simple test methods.

For this reason, the reverse pressure chamber solves this problem. As an option of capillary rheometer, it can be selected to simulate the processing process to obtain data, especially in highpressure processes, such as melt pump, injection mode and extrusion die, because there is wall slip in the extrusion process.
