STRUKSILON 8007

Application Fields

STRUKSILON 8007 was developed as universal silicone surfactant for production of polyurethane rigid foam based on polyester and polyether polyols.

STRUKSILON 8007 is applicable in combination with the usual blowing agents in systems for 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 insulations in the construction industry and for systems in the block foam are

Chemical and Physical Properties

According to its chemical structure STRUKSILON 8007 is a polyether modified polydimethyl siloxane resistant to hydrolysis.

General chemical structure:

STRUKSILON 8007 is a clear, colourless to slightly yellow liquid of middle viscosity, has strong surfactant properties and is miscible with water at room temperature.

Viscosity at 25°C [mPas] 500-1300
Turbidity point [°C] 31
Density at 25°C [kg/m3] 1,06-1,08
Flash point (DIN/ISO 2562) [°C] >100
Refractive Index   1,449-1,454

Technical Properties

STRUKSILON 8007 induces a balanced relation between good flow performance, fine-cell structure, low thermal conductivity and good dimensional stability in produced rigid foams.

STRUKSILON 8007 shows excellent emulsifying behaviour and compatibility in formulations based on polyesterpolyols and higher functional polyetherpolyols.

Finally, STRUKSILON 8007 is applicable in systems based on polyesterpolyols as well as in systems based on polyetherpolyols or mixtures of both.

STRUKSILON 8007 can be used in combination with all usual blowing agents but especially in

n-pentane, cyclopentane and 141

Recommended Dosage

Usually, STRUKSILON 8007 is applied in quantities of 0.5 to 1.5 php (parts on 100 parts polyole). We recommend to adjust the optimum dosage to the corresponding formula. However, a concentration of 3 php should not be exceeded.

Product Safety and Handling

Usually, STRUKSILON 8007 is applied in quantities of 0.5 to 1.5 php (parts on 100 parts polyole). We recommend to adjust the optimum dosage to the corresponding formula. However, a concentration of 3 php should not be exceeded.
