XIAMETER(TM) PMX-200 Silicone Fluid 600,000 cSt

XIAMETER(TM) PMX-200 Silicone Fluid 600,000 cSt is a high-viscosity polydimethylsiloxane polymer that is primarily used for foam control in nonaqueous processes. In petroleum processing, it provides effective foam control at extremely low dosage levels. This product is also suitable for use in personal care applications. The high-molecular-weight dimethicone provides easy combing and detangling for wet or dry hair and adds softness, smoothness, and gloss.

a usable life of 36 months from the date of production.

Usage Method

As an Antifoam

The starting level of active material recommended is 10 ppm; in many cases, the optimal usage level may be approximately 1 ppm. XIAMETER PMX-200 Silicone Fluid is typically prediluted in a hydrocarbon solvent, such as white spirits, toluene, xylene, diesel, naphtha or another low-molecular-weight petroleum fraction, and added continuously by metering pump.
The viscosity of the XIAMETER PMX-200 Silicone Fluid should be selected to suit the
application, with primary selection criteria including insolubility in the foaming system,
working temperature and ease of handling.

As a Conditioning Additive
For personal care applications, XIAMETER PMX-200 Silicone Fluid should be pre-emulsified to the desired particle size, incorporated into a shampoo base and post-stabilized. Alternatively, it can be directly emulsified into a hair care formulation.

Product Applications
  • For foam control in petroleum production and refinery operations
  • Conditioning agent for hair care products, particularly conditioning shampoos and rinse-off conditioners
  • High-viscosity dimethicone fluid.
  • Linear polydimethylsiloxane polymers typically have the following typical chemical composition: (CH3)3SiO[SiO(CH3)2]nSi(CH3)3.
