Engineering plastics are widely used in automotive parts, electric tool casings, transmission plastic components, and office equipment gears. However, common plastics have relatively high friction coefficients, which can cause noise, wear, and heat generation during continuous operation of the components, thereby shortening the product's service life. Modified silicone oil, with its excellent lubrication properties, has become an important modified raw material for oil-free self-lubricating plastic formulations, effectively solving the problem of friction and wear in engineering plastics.
During the pelletization stage of engineering plastics such as PA nylon, POM, PBT, and PC/ABS alloys, compatible modified silicone oil is added and evenly dispersed within the resin matrix. During the operation of the components, the silicone oil slowly migrates to the friction interface, forming a persistent lubricating film, reducing the friction between plastics and the friction coefficient between plastics and metals, reducing the generation of friction heat, and inhibiting the softening and wear of plastics at high temperatures. Compared to solid lubricants, silicone oil has better dispersibility and does not affect the mechanical properties such as impact strength and tensile strength of the substrate, balancing rigidity and lubrication performance.
Long-term operation of a large number of plastic transmission structures can easily generate harsh friction noises. After adding silicone oil modification, the friction interface becomes smoother, buffering vibration and friction, achieving significant noise reduction effects. It is widely used in printer gears, household appliance transmission components, and plastic parts for electric tools. For outdoor-used engineering plastic components, the silicone film simultaneously provides hydrophobic protection, resisting the erosion of rain and moisture, and delaying the hydrolysis and aging of the substrate.
During the formulation development process, the proportion of silicone oil added needs to be precisely controlled. Excessive addition can cause the surface of the product to precipitate, reducing surface adhesion, and affecting screen printing and bonding processes. IOTA compatible modified silicone oil has been optimized in molecular structure, has good compatibility with engineering plastics, controlled precipitation, and is suitable for the entire process of extrusion pelletization and injection molding. With the popularization of the lightweight concept, the trend of plastic parts replacing metal parts is accelerating, and the demand for wear and noise-reducing modified silicone oil continues to rise, helping high-end engineering plastic products achieve performance upgrades.
