Substance identity
The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas.
Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed.
The EC Number is the numerical identifier for substances in the EC Inventory. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). More information about the EC Inventory can be found here.
If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9.
The EC or list number is the primary substance identifier used by ECHA.
The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. More information about CAS and the CAS registry can be found here.
The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure.
The molecular structure is based on structures generated from information available in ECHA’s databases. If generated, an InChI string will also be generated and made available for searching. This information is only displayed if the substance is well-defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure.

Product Description
Silway 520 is a polydimethylsiloxane polymer manufactured to yield essentially linear polymers in a wide range of average kinematic viscosities.
Dimethyl silicone oil is colorless,transparent, odourless and non-toxic oil liquid. The viscosity increases with the added of N value of SI-O chain, from highly mobile liquid to thick semisolid

Typical Applications
Usage
As Defoamer
Due to the feature of low surface tension, insoluble, and chemical stability, Dimethyl Silicone Oil is used as defoamer/antifoamer in petrochemical industry, medical industry, pharmaceutical industry, food processing, texture, printing and dyeing, paper industry., etc.
As Lubricant
As lubricant, Dimethyl silicone oil is suitable for rubber, plastic bearings, and gears. Also be proper for rolling friction between steel materials to steel or other metals under high temperature.
Remarkable: In general case, Dimethyl silicone oil is not suggested as lubricant between metals in room temperature.
As Mold Release Agent
Due to the non-stick ability on rubber, plastic and metal, etc.,Dimethyl Silicone Oil is often used as mold releasing agent during molding process of rubbers and plastic products.
As mold releasing agent, Dimethyl Silicone Oil not only demold easily, but leaves clean, smooth,and clear grain on the surface of products.
As coating of lnsulation, dust/mould proof
Applying a coat of Dimethyl Silicone Oil on the surface of glass or ceramics, then making heat treating by 250 - 300 ºC, a semi permanent waterproof, mould proof and insulation membrane.
