High Temperature Silicone Fluids

Categories: , , , , , , , , , ,


High Temperature Silicone Fluids are Newtonian fluids calibrated at 25°C, 93.3°C and 149°C. These fluids are accurate to ±1% of viscosity value and are recommended for use with the Brookfield Thermosel accessory.

Confused about which standards you need? See our FAQ section.


  • Accuracy: ±1% of viscosity value
  • Excellent temperature stability
  • Recommended for use with Brookfield and most other rotational viscometers
  • Most economical
  • Special viscosity values and temperature calibrations available upon request

REACH is the European Community Regulation on chemicals and their safe use (EC 1907/2006). It deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The law entered into force on 1 June 2007.

The aim of REACH is to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances. At the same time, REACH aims to enhance innovation and competitiveness of the EU chemicals industry.
