Applications of Phenyl Methyl Silicone Oil LC-P261

  • Special medium for high-temperature heat setting conditions in textile printing and dyeing: Suitable for textile heat setting rollers and high-temperature ironing equipment, it has both thermal conductivity and roller surface protection functions. It is not easy to evaporate and lose during continuous high-temperature setting processes, ensuring the uniformity of fabric setting while reducing equipment roller surface adhesion wear.

  • Heavy duty industrial damping and large buffering mechanism medium: Used as damping fluid for industrial heavy equipment, ship precision instruments, and large hydraulic buffers, with viscosity characteristics more suitable for heavy load conditions and stable damping torque at high and low temperatures

  • High voltage electrical terminal sealing and outdoor insulation protection: For outdoor high-voltage transformers, wiring terminals, and cable joints, insulation sealing liquid is used with a viscosity of 150 and controllable flowability. After sealing, it is not easy to flow and sag, and can form a dense insulation layer. It also takes into account moisture resistance, UV resistance, and high temperature insulation, and is suitable for long-term outdoor electrical protection.

  • Long term lubrication and anti oil splash protection for high-temperature transmission chains: Applied to high-temperature transmission chains in glass annealing and ceramic firing production lines, the high viscosity makes them more adhesive and less prone to oil splash during high-speed operation

  • Optical components anti fog and water repellent and cavity sealing protection: As a sealing protective liquid for infrared optical lenses and precision optical instrument cavities, relying on high refractive index and moderate viscosity, it can form an anti fog and water repellent film, fill the gaps in the instrument cavity, prevent water vapor and dust from entering, and balance optical transparency and sealing protection.

  • Special rubber plasticizing modification and thick film high-temperature demolding: used as a high-temperature resistant plasticizing modification additive for silicone rubber and fluororubber to enhance the temperature resistance and flexibility of rubber products; Simultaneously suitable for high-temperature molding of carbon fiber and composite materials, this thick film release agent has better film-forming properties than low viscosity products, and the surface of the product is smooth and residue free after demolding.
