STRUKSILON 8027

Application Fields

STRUKSILON 8027 is a specifically designed silicone surfactant for appliance application and other applications where god flowability is required, like pipe insulation and hot water boiler production.

Chemical and Physical Properties

According to its chemical structure STRUKSILON 8027 is a polyether-modified polydimethyl siloxane resistant to hydrolysis.

STRUKSILON 8027 is at room temperature a clear ,colorless to slightly yellow liquid of middle viscosity.

General chemical structure:

Typical Properties:

Viscosity at 25°C	[mPas]	1000
Density at 25°C	[kg/m³]	app. 1.047
Flash point (DIN EN 22719)	[°C]	>100
Refractive Index at 25°C		1,446

Technical Properties

STRUKSILON 8027 was specifically designed to combine excellent flowability and improved demould properties with very good insulation properties .For this reason it is especially recommended for ystems used in appliance application, pipe insulation or other applications where excellent flowability is needed. It s mainly focused on systems where cyclopentane or mixtures of cycle-and isopentane are used as blowing agents.

Based on its extraordinary performance, the use of TRUKSILON 8027 can result in improved λ -value, educed flow factor and reduced post expansion of the foam It offers good miscibility with most of the common polyol systems.

STRUKSILON 8027 could also be used in pentane blown continuous panel production. However, for this application we recommend our products STRUKSILON 8005 ,STRUKSILON 8007 and STRUKSILON 8026 which show either enhanced emulsification or improved FR properties.

Recommended Dosage

Usually, STRUKSILON 8027 is applied in quantities of 0.5 to 1.5 php (parts on 100 parts polyol). We recommend adjusting the optimum dosage to the corresponding formula. However, a concentration of 3 php should not be exceeded.

Product Safety and Handling

STRUKSILON 8027 is not a hazardous material for the purposes of hazardous materials regulation.

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

Packaging, Storage and Transport

Storage stability	12 months in closed original containers if transported and stored at a temperature between 1 and 30 °C.
Packaging	200 kg drums 1000 kg containers(IBC)
