Analysis of additives and filler types that change the performance of PP polypropylene granules

As a common plastic material, the properties of PP polypropylene granules can be changed and enhanced by adding different types of additives and fillers. This article will introduce you to some common additives and filler types that can be added to PP polypropylene granules to change its properties and application range.

enhancer

Reinforcing agents can improve the strength and stiffness of PP polypropylene granules. Common reinforcements include glass fiber, carbon fiber and nanofillers. These reinforcements work by increasing the strength and stiffness of the particles, allowing them to perform better under higher loads and pressures.

flame retardant

Flame retardants can improve the flame retardant properties of PP polypropylene granules and reduce the risk of fire. Common flame retardants include flame retardant fillers and flame retardant additives. They can form a flame retardant layer in PP particles to prevent the spread and burning of flames.

Antioxidants

Antioxidants can extend the service life of PP polypropylene granules and reduce the effects of oxidation and aging. Common antioxidants include heat stabilizers and UV absorbers. They can prevent PP particles from oxidation reactions under high temperature and ultraviolet irradiation, maintaining their physical properties and appearance stability.

Lubricant

Lubricant can improve the processing performance and surface smoothness of PP polypropylene granules. Common lubricants include stearate and polyethylene wax. They can reduce the friction coefficient of PP polypropylene granules, reduce heat and energy loss during processing, and improve production efficiency and product quality.

Pigments and fillers

Pigments can add color and appearance to PP polypropylene granules, making them more attractive. Common pigments include organic pigments and inorganic pigments. Fillers can change the density, thermal conductivity and mechanical properties of PP polypropylene granules. Common fillers include glass beads, graphite, and silicates.

By adding different types of additives and fillers, the properties and application range of PP polypropylene granules can be changed. Common additives and fillers include reinforcing agents, flame retardants, antioxidants, lubricants, pigments and fillers, etc. Selecting suitable additives and fillers can improve the strength, heat resistance, flame retardancy, processing performance and appearance of PP polypropylene granules according to specific needs and application requirements. When using additives and fillers, the addition amount should be reasonably controlled according to the requirements of the production process and use environment to ensure the performance and quality of PP polypropylene granules.
