STRUKSILON 8005

Application Fields

STRUKSILON 8005 was developed as universal silicone surfactant for production of polyurethane rigid foam based on polyether polyols.

STRUKSILON 8005 is applicable in combination with the usual blowing agents in nearly all known PU rigid foam applications e.g. sandwich elements (CLBS), insulation material for production of cooling and heating appliances and facilities, roof and wall insulation in the construction industry and for systems in the block foam area.

Chemical and Physical Properties

According to its chemical structure SAXOL STRUKSILON 8005 is a polyether modified polydimethyl siloxane resistant to hydrolysis.

General chemical structure:

STRUKSILON 8005 is a clear, colourless to slightly yellow liquid of middle viscosity, has strong surfactant properties and is miscible with water at room temperature.

Typical Properties:

Viscosity at 25°C	[mPas]	700-1300
Turbidity point	[°C]	41
Density at 25°C	[kg/m³]	1.05
Flash point (DIN/ISO 2562)	[°C]	>100
Refractive Index		1.450-1.454

Technical Properties

STRUKSILON 8005 induces a balanced relation between good flow property, fine-cell structure, low thermal conductivity and good shrinkage stability in produced rigid foams.

STRUKSILON 8005 shows an excellent emulsifying behaviour in formulations containing different functional polyetherpolyols. In mixtures with polyesterpolyols slight turbidity may occur but the effectiveness of the silicone surfactant will not be impaired.

STRUKSILON 8005 can be used in combination with all usual blowing agents. SAXOL STRUKSILON 8005 is especially suited for 141b- and n-pentane blown systems and shows excellent results in these systems.

Recommended Dosage

Usually, STRUKSILON 8005 is applied in quantities of 0.5 to 1.5 php (parts on 100 parts polyol). We recommend to adjust the optimum dosage to the corresponding formula. However, a concentration of 3.0 php should not be exceeded.

Product Safety and Handling

STRUKSILON 8005 is not a hazardous material for the purposes of hazardous materials regulations.STRUKSILON 8005 does not contain aminic components.
