Product Description

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

Usage Guidelines

As Defoamer

Due to low surface tension, insolubility, and chemical stability, Silway 520 is used in petrochemical, medical, food processing, textile, and paper industries.

As Lubricant

Suitable for rubber, plastic bearings, and gears. Effective for rolling friction between steel and other metals under high temperatures.

As Mold Release Agent

Used for non-sticking in rubber, plastic, and metal molding. Leaves a clean, smooth, and clear grain on the product surface.

As Insulation Coating

Applied to glass or ceramics and heat-treated at 250-300ºC to form a semi-permanent waterproof and mould-proof membrane.

Frequently Asked Questions

1. What is the chemical composition of Silway 520? Silway 520 is a polydimethylsiloxane (PDMS) polymer, commonly known as dimethyl silicone oil or dimethyl silicone fluid.

2. Is Silway 520 safe and non-toxic? Yes, Silway 520 is essentially odorless, tasteless, and non-toxic, making it suitable for various industrial and medical applications.

3. Can it be used as a lubricant for metals? It is suitable for rolling friction between steel and other metals under high temperatures. However, it is generally not suggested as a lubricant between metals at room temperature.

4. What are the available packaging options? The product is typically supplied in 200L drums or large IBC tanks to accommodate high-capacity industrial needs.

5. How should Silway 520 be stored for maximum shelf life? It should be stored in closed containers. Under proper storage conditions, it has a shelf life of 36 months.

6. What makes it an effective mold release agent? Its non-stick properties on rubber, plastic, and metal allow for easy demolding while leaving a clean and smooth surface on the finished products.
