Applications of 600,000 Viscosity Dimethyl Silicone Oil
600,000 viscosity dimethyl silicone oil is an ultra-high viscosity polydimethylsiloxane. It possesses extremely strong viscoelasticity, excellent film-forming properties, high temperature resistance, weather resistance, low volatility, high insulation, strong hydrophobicity, and long-lasting lubrication. Its high viscosity and large molecular weight make it difficult to migrate or precipitate in the system, resulting in significantly better long-term stability than ordinary medium- and low-viscosity silicone oils. It is widely used in industries such as silicone rubber, damping lubrication, electrical insulation, adhesives, coatings, daily chemicals, and rubber and plastics processing.
In the silicone rubber products industry, 600,000 viscosity dimethyl silicone oil is used as a core additive for toughening, softening, internal lubrication, and mold release modification of high-temperature vulcanized silicone rubber, liquid silicone rubber, and room-temperature vulcanized silicone rubber. It can improve the processing fluidity of the rubber compound, enhance the surface finish and soft feel of the product, assist in anti-yellowing and aging resistance, and simultaneously enhance the tensile and resilience properties of silicone rubber. It is suitable for high-end seals, silicone buttons, medical silicone products, silicone tubes, insulators, and other products.
In the field of damping and lubrication, thanks to its ultra-high viscoelasticity, it can be used as a damping oil, shock absorber, and buffer medium for precision instruments, meters, home appliances, and automotive parts, providing stable damping, vibration reduction, and noise reduction while maintaining viscosity stability under high and low temperature environments. Simultaneously, it can serve as a long-lasting grease base oil for metal, plastic, and rubber friction pairs, forming a dense lubricating film that is resistant to high and low temperatures, wear-resistant, and suitable for extreme operating conditions where ordinary lubricating greases cannot meet the requirements.
In the field of electrical insulation, it is used as an insulating filler, moisture-proof sealant, and heat dissipation medium for high-voltage cables, transformers, instrument transformers, capacitors, and electronic components. Relying on its high insulation strength, low volatility, and resistance to damp heat, it fills gaps in equipment, isolates moisture, improves insulation levels and long-term operational stability, and reduces the risk of leakage and breakdown.
In the silicone pressure-sensitive adhesive and adhesive industry, it is used as a tackifier, thickener, and flexibility modifier in combination with MQ silicone resin. It can adjust the initial tack, holding power, and peel strength of the adhesive layer, improve its resistance to high and low temperatures and aging, and enhance the flexibility of the tape. It is widely used in silicone double-sided tapes, high-temperature tapes, electronic insulating tapes, and other products.
In the coatings and inks industry, it is used as a high-temperature leveling agent, slip agent, and hydrophobic additive. Added to industrial paints, high-temperature coatings, and anti-corrosion coatings, it reduces the surface tension of the system, improves the coating's smoothness, scratch resistance, and stain resistance, enhances film-forming properties and weather resistance, and reduces surface defects such as pinholes and fisheyes.
In the daily chemical and personal care field, it is used in high-end face creams, hair oils, hair waxes, and makeup products as a film-forming agent, skin feel modifier, and thickener. It provides a smooth and delicate feel, enhances the product's waterproof, sweat-resistant, and makeup-holding effects, and improves the stability and formability of the paste.
In the rubber and plastics processing and mold release industry, as a highly efficient and long-lasting mold release agent, it is suitable for demolding rubber, plastic, polyurethane, and other products, without contaminating the mold or product surface, improving demolding efficiency and product surface smoothness.
In the textile and building materials industry, it can be used to soften, smooth, and waterproof chemical fiber and blended fabrics, giving the fabric a lasting soft feel and hydrophobic properties; it can also be used to modify sealants and waterproof materials, improving material flexibility, water resistance, and workability.
