PP reinforced with glass fiber is a compounding and modification process based on PP, glass fiber and additives. The purpose is to improve the strength of PP, making it a wide range of applications. It is widely used in the structure parts.
The advantage of PP fiber glass reinforce:
- It is more temperature resistant.
- The shrinkage is getting less
- The impact resistance is improved greatly
- Many other properties have been greatly improved, such as extension strength, compressive strength, bending strength,
The basic components needed for this application:
Raw material dealing system:
Gravimetric feeder/ premixer+ volumetric feeder
Twin Screw Extruder
High torque side feeder is highly suggested in order to get a higher speed & torque. Save energy 15%. An ideal screw profile is very important, on one hand, we have to make the glass fiber, PP, additive a good mixing and dispersion, on the other hand, we need to keep a certain length of the glass fiber in order to get a better property.
Strand Pelletizing system
This system includes strand die head, water bath, air knife and pelletizer.
