STRUKSILON 8120

Application Fields

STRUKSILON 8120 was developed as universal silicone surfactant of high potency for the production of conventional as well as flame retardant flexible polyurethane slabstock foam based on polyether polyols.

STRUKSILON 8120 is applicable in systems for nearly all known flexible PU slabstock foam applications and technologies like production of seats, chairs, mattresses etc. in the furniture and automotive industry and for all kinds of damping devices.

Chemical and Physical Properties

According to its chemical structure STRUKSILON 8120 is a polyether-modified polydimethyl siloxane resistant to hydrolysis.

General chemical structure:

STRUKSILON 8120 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:

Turbidity point	[°C]	34
Density at 25°C	[kg/m³]	1023
Flash point (DIN /ISO 2562)	[°C]	>100
Refractive Index at 25°C		-1,449

Technical Properties

STRUKSILON 8120 is a silicone surfactant of high potency. The special structure of STRUKSILON 8120 guaranties wide processing latitude and allows the use in flame retardant as well as non-flame retardant foams.

Due to the high potency STRUKSILON 8120 is recommended for the production of flexible PU slabstock foams with a density range of approximately 12-30kg/m³.

It induces a balanced relation between a high quantity of open cells and good air flow as well as a uniform cell and density distribution combined with good physical and mechanical properties in produced flexible block foams.

STRUKSILON 8120 shows an excellent emulsifying efficiency and compatibility when using polyetherpolyols.

Furthermore, STRUKSILON 8120 possesses wide processing latitude according to the used amount and different raw materials.

STRUKSILON 8120 contains only negligible amounts of volatile compounds and is suitable for applications with anti-fogging requirements.

STRUKSILON 8120 can be used in combination with all usual co-blowing agents like methylenechloride or acetone.

Recommended Dosage

Usually, STRUKSILON 8120 is applied in quantities of 0.6 to 1.5 php (parts on 100 parts polyol). We recommend adjusting the optimum dosage according to the corresponding formula, type and amount of activators, catalysts, blowing agents and the activity of raw materials.
However, a concentration of 2,5 php should not be exceeded.

Product Safety and Handling

STRUKSILON 8120 is not a hazardous material for the purposes of hazardous materials regulations.

Further information regarding safety, toxicology, special properties of the product, transport and storage are given in the safety data sheet.
