Four Special Applications Of Underwater Pelletizing System

There are 4 special applications that can only be handled by underwater pelletizing systems.

1) Round particles with diameter ≤1mm.

Round particles can only be produced through underwater pelletizing systems.
Microparticles are mostly used in the preparation of high-concentration masterbatch. The particles are very small, and the dispersion effect can be achieved without or using a small amount of dispersant. This results in significant cost savings. Masterbatches in particulate form are easier to handle, better metered and dust-free.

2) High output

Other types of pelletizing systems have difficulty in handling outputs of more than 1000kg/h. Underwater pelletizing systems can handle throughputs up to 50 tons/hour.

3) Soft materials with hardness less than Shore A40

Many types of soft materials, such as TPE/TPV/EVA/hot melt adhesive, can only be made through underwater pelletizing system.

4) Synthesis and reaction of polymers

Polymerization, reactive extrusion, and transformation from liquid to particles can usually be achieved through underwater cutting of many materials.

Aplicações gerais

• PP, PE and its compounds, various of thermoplastic elastomers, PA, TPU, EVA, and other hot melt adhesives.
• Extensive heat and mass transfer, narrow residence time distribution, large surface-to-volume ratio, continuous operation. Ideal for high-viscosity, high-temperature reaction systems.
• Continuous polymerization or reactive extrusion like dynamic vulcanization, crosslinking, grafting, and chain extension of PUR, PA, POM, PEI, PC, PMMA, PBT, PPS, etc.
