Viscosity Silicone Oils IOTA PDMS 47V50 - 47V1000
 
	Description: IOTA
PDMS 47V50 - 47V1000 are straight chained polydimethylsiloxane fluids. 
	Applications: 
	IOTA PDMS 47V50 A2 - 47V1000 are
used as: 
	Thermostatic fluids (-50℃
to +200℃), 
	Anti-blotting products for
photocopying machines, 
	Thinning and plastifying agents for
RTV’s and silicone sealants, 
	Raw material for Antifoam 
	Lubricating and heat protecting
agents for textile threads ( synthetic sewing threads), 
	Ingredients in maintenance products
(polishes, wax polishes, floor and furniture polishes, etc.), 
	Paint additives (anti-cratering,
anti-floating/flooding and anti-scratching effects, etc.), 
	Water repellent treatment: 
	-of powders (for paints and
plastics), 
	-of fibers: glass fibers, 
	Release agents (mould release of
plastics and metal castings), 
	Lubricants (lubrication of
elastomers or plastics on metal), 
	Surfactants for styrene-butadiene
foam. 
	HCR application to reduce hardness 
	Properties: 
	Very good resistance to high and low
temperature, 
	Good combustion resistance, 
	Low surface tension, 
	High compressibility, 
	Absence of ageing upon exposure to
atmospheric agents, 
	Good oxidation resistance, 
	Little change in viscosity with
temperature, 
	Good resistance to high and
prolonged shear stress.
