Dispersion Quality Validation Using Filter Test Machines

Mar 8, 2022 | News & Article

Technology has become a part of human life today. It is undeniable that the rapid development of technology has now affected all aspects of daily life. Realizing this, we are committed to innovating and presenting products that provide positive benefits for human life.

As proof of our commitment to maintaining product quality, we strive to facilitate our lab with equipment that supports applications and meets customer needs. One of them is the filter test machine which functions to measure a value called the Filter Pressure Value (FPV).

What is FPV?

Before discussing how the Engine Test Filter works, it’s a good idea to discuss a little about what FPV is. FPV are impurities that settle on the engine filter. The smaller the FPV value, it can be indicated the smaller the value of impurities retained by the filter machine.

Likewise, when the FPV value is more excellent, the filter machine will retain the impurities or deposits. So this FPV plays a significant role in helping validate the colorant/masterbatch that has been dispersed whether it is well or not.

How does it work?

The FPV engine was used when conducting trials. That is when the material is fed into the filter machine. Then the material entering machine will be melted and homogenized in the extruder at a temperature that has been adjusted to the existing conditions. 

Then the material will be passed through a filter at a specific pressure with a constant volume and flow. The filter will clog at certain particle conditions and will cause an increase in pressure. Now, the value of this pressure increase is what we will measure as FPV.
