Application

Chemical & Composite Materials

Rongpai underwater pelletizing systems are widely used in the chemical and composite materials industry, processing functional plastics, flame-retardant materials, glass-fiber reinforced plastics, carbon-fiber composites, and various modified plastics.
These materials require precise control of pellet size, uniform distribution, and flowability to meet downstream processes such as injection molding, extrusion, and blow molding. Rongpai underwater pelletizing systems operate stably under high temperature and high viscosity, ensuring high-quality pellets for filled and reinforced composite materials.

The application of underwater pelletizing systems in the chemical and composite materials industry primarily covers filled and modified materials, high-strength reinforced plastics, and functional plastics.

Functional Plastics

Flame-Retardant Plastics (FR-PP, FR-PA, FR-PC, etc.): Films, pipes, packaging bags, cable sheaths

Antistatic Plastics: Electronic product packaging, semiconductor equipment housings

High Heat-Resistant Plastics: High-temperature automotive parts, aerospace components, electronic insulation parts

High-Filler Masterbatch

Calcium Carbonate Masterbatch (CaCO₃-filled PP/PE): Plastic bags, food packaging, injection-molded products

White Masterbatch (TiO₂-filled): Plastic films, plastic pipes, home appliance housings

Functional Masterbatch (UV stabilizers, antibacterial agents): Outdoor plastic products, medical devices
