Polydimethylsiloxane (PDMS) fluids are available in any viscosity from 5 - 1M centistoke. These silicone fluids can be used neat or as performance modifiers in many systems. The unique properties associated with silicone allows them to be used in many applications.
Release agents
Resistance to high and low temperatures, do not form residues on mould surfaces, one application often sufficient for many applications. Typically used for demoulding rubber and plastic parts.
Lubricants
Excellent slip characteristics as well as low surface friction and high water repellency finds uses typically in films, cutting tools, extrusions and sewing threads.
Damping media
Physical properties are practically unchanged at temperatures above 200°C. Typically used in speed regulators, fluid clutches (e.g., fans), instruments, shock-absorbers etc.
Hydraulic fluids
Excellent viscosity / temperature characteristics, high compressibility and stability under shear. Uses include shock absorbers, pumps, brake cylinders.
Water repellents
Low surface tension and high hydrophobicity. Can be used on glass, fabrics, laminates, ceramics.
Antifoams
Effective in even the smallest amounts, they can be used to prevent foaming in non aqueous systems such as mineral and vegetable oils.
Creams polishes
Gloss retaining and imparting a silky feel, they are found in car and furniture polishes, shoe creams and floor polishes.
Speciality Silicone Fluids
Cyclic polydimethyl siloxanes are volatile silicones which evaporate at different temperatures. These are widely used in Personal Care as they are clear and colourless, insoluble in water but soluble in alcohol.
PennWhite
Ltd can blend silicone fluids of different viscosities from 10 cst to 300,000
cst to suit a customers own requirements. These special blends can then be used
as supplied or incorporated into specialised products. Examples include Supersil
861 and 862 which are blends of high and low viscosity oils, designed to give
the high gloss properties of heavy oils together with the manageability of a
lower viscosity material.
Silicone
Fluids are non-toxic and do not cause skin irritation or allergic reaction.
They are odourless, tasteless and non-reactive. Due to this inertness they are
used in cosmetic formulations such as skin care creams, sun tan lotions, body
lotions and hair care formulations. Silicone fluids offer excellent water repellency
for skin care preparations and improve the penetration / spreading properties
of the products. Silicone Fluids are used as hair care additives to enhance
the gloss, softness, body and manageability of the hair.
(Current products include PW202, PW214, PW256)
Silicone
solutions are mixtures of silicone oils and modified silicone oils in solvent.
These solutions are particularly useful in the building industry as masonry
water repellents. Other applications of silicone solutions are as release solutions
and lubricants in spray can form.
(Current products include Supersil
No 1 and Supersil
No 2, PC48HF).
