Polydimethylsiloxane Silway520

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.

Key Features
