VMQ rubber seal, also known as silicone rubber seal, is a rubber seal polymerized from polydimethylsiloxane (PDMS).
Although the size and quality of aero-Aircraft engine seals materials and their products are small, their application parts are wide, and their role is very critical, and their performance level and reliability can directly affect the overall performance and reliability of aero-engine.
VMQ O-rings are made from silicone rubber, a synthetic elastomer known for its excellent thermal stability and flexibility. The acronym “VMQ” stands for Vinyl Methyl Quality and refers to the specific type of silicone polymer used in the manufacturing process. These o-rings are widely used in the automotive, aerospace, medical, food processing and other industries.
The silicone used by faucet seals is a liquid raw material that has unique advantages during processing and can maintain accuracy, quality, and performance over long periods of time. Other properties include strong chemical resistance, excellent thermal resistance, dielectric strength and cold deflection. Silica gel also has good mechanical and electrical damping properties. Provides excellent performance conditions for faucet seals.
浄水器用シーリングリングは、浄水システムにとって重要な部品です。浄水された水と外部環境との間のバリアとして機能し、汚染物質がシステムに侵入するのを防ぎます。シーリングリングは、ろ過・浄化プロセスを効果的に密閉することで、飲料水の安全性を確保します。適切なシールがなければ、浄化された水が汚染の危険にさらされ、浄水システム全体が機能しなくなる可能性があります。
In specific chemical pipeline applications if you want choose VMQ rubber seals, please consult Linde Polymer’s professional engineers and follow relevant standards and specifications based on actual conditions and requirements to ensure that the selected VMQ material seals meet the requirements and can provide good sealing effects.
Density: The density of VMQ rubber seals is typically between 1.1 and 1.3 g/cm³.
Hardness: Typically measured on the Shore A scale, which ranges from 30 to 80 and indicates the hardness and softness of rubber.
Elastic modulus: generally between 2 and 10 MPa, indicating the deformation and recovery ability of rubber when subjected to stress.
Elongation at break: usually between 200% and 600%, indicating the ductility of the rubber before it is stretched to rupture.
Thermal conductivity coefficient: usually between 0.15 and 0.3 W/(m·K), indicating the ability of rubber to conduct heat.
Corrosion resistance: VMQ rubber seals have good acid, alkali and solvent resistance, and can resist corrosion by many common chemicals.
Ozone resistance: VMQ rubber seals have good resistance to ozone and can be used for a long time in an ozone environment without deterioration.
Oxidation resistance: VMQ rubber seals are usually not susceptible to oxidation and aging when exposed to oxygen for a long time.
Tensile strength: generally between 5 and 10 MPa, indicating the tensile properties of rubber under tensile force.
Compression deformation: usually between 30% and 50%, indicating the rubber’s ability to compress under pressure.
Tear strength: generally between 10 and 30 N/mm, indicating the rubber's resistance to tearing force.
Molding: VMQ rubber seals have good molding properties and can be manufactured by extrusion, compression molding or injection molding.
Adhesion: VMQ rubber seals are easy to bond with other materials, such as metal, plastic, etc.
Cutability: VMQ rubber seals can be processed and customized by cutting, punching, etc.
It is important to note that specific physical, chemical, mechanical and processing properties may vary depending on the manufacturer, product formulation and processing conditions. Therefore, when selecting and using VMQ rubber seals, it is recommended to refer to the specific product information and technical data sheets provided by the manufacturer for accurate performance parameters.
It should be noted that specific application areas may vary depending on the industry, product requirements and environmental conditions.
