Filter Pressure Value Tester

Product Introduction 
Filter Pressure Value Tester consists of a single-screw extrusion system, a melt pump, a screen changer, and a computer measurement and control system. By measuring the pressure difference (FPV value) of the melt before and after passing through the filter screen, it accurately quantifies the dispersion effect of colorants and fillers in color masterbatches and filled masterbatches — the smaller the FPV value, the better the dispersion.
DESCRIPTION
Key Features
● High-Precision Sensing System 
Equipped with an internationally renowned brand (GEFRAN) melt pressure sensor, achieving a pressure measurement accuracy of 0.5% F.S., ensuring reliable FPV value calculation. 
 
● Professional Melt Pump 
High-temperature precision melt pump ensures test repeatability. 
 
● Durable Screen Changing Structure 
Configured with a manual plate-type screen changer. The screen plate is nitrided for high hardness and wear resistance, supporting quick replacement of screens with different mesh counts. 
 
● Intelligent Measurement and Control Software
 Proprietary developed software displays real-time pressure-time curves, automatically calculates FPV values, and supports functions such as data storage.
 
Applications & Industries
● Industries: Plastics, Color Masterbatch, Modified Plastics, Chemical Industry, New Materials Applications: 
 
● Masterbatch Dispersion Testing: Primarily used for measuring and characterizing the dispersion of materials such as color masterbatches and filled masterbatches. The dispersion effect is judged by testing the Filter Pressure Value (FPV) — a smaller FPV value indicates better dispersion. 
 
● Filler Material Evaluation: Assessing the dispersion uniformity of fillers like calcium carbonate and talc powder within the melt.
