FPV Filtration Pressure Value Tester is specially developed for plastic color masterbatches, filler masterbatches and modified polymer materials.
CMSI-25/03 FPV Filtration Pressure Value Tester is a high-precision lab instrument for quantitative testing and characterization of color masterbatch and filler masterbatch dispersion. Widely used in plastic, colorant and chemical industries, it consists of a 25mm single-screw extrusion unit, melt pump system, screen changer and intelligent control system.
With precision extrusion, constant-flow melt pump and imported high-accuracy pressure sensors, the equipment melts and extrudes masterbatch with base material at stable speed. It monitors real-time melt pressure before the filter screen and automatically calculates the FPV value to quantify dispersion performance — the smaller the FPV value, the better the dispersion effect. It effectively solves the drawbacks of traditional empirical testing without data support, and is compatible with PP, PE, PET, PS, PA and other common polymer materials.
Product Features
●High Precision & Reliable Data
Adopts imported high-precision pressure sensors to capture subtle melt pressure changes. FPV results provide objective quantitative data for quality inspection and material research comparison.
●Stable Operation & Easy Control
Servo-driven single-screw design offers 0–120 rpm stable speed with low noise. High-precision melt pump ensures steady melt output. Self-developed control software features intuitive interface and simple operation.
●Durable Structure & Flexible Screening
Plug-in wear-resistant screen changer allows fast replacement of different standard filter screens, meeting testing requirements for various color and filler masterbatches.
●Customized Solution
Screw specification, temperature range and pressure range can be customized to fit enterprise routine quality control and advanced material R&D demands.
Operating Procedures
1)Clean the barrel with pure base material and mix color masterbatch with base material in standard proportion.
2)Install filter screen, feed base material, and adjust screw and melt pump speed to stabilize inlet pressure at 30–60bar and maintain stable initial screen pressure.
3)Replace base material with prepared masterbatch mixture, start testing and record the complete pressure variation curve.
4)After mixture extrusion, add a small amount of pure base material to finish the test without material interruption.
