LIPOLAN® F 2820F is an aqueous dispersion of a reinforced styrene-butadiene copolymer with a high solids content. The emulsifier used is an alkaline salt of fatty acids, which gives the product good stability and foamability. Moulded foam based on LIPOLAN® F 2820F exhibits a medium high indentation hardness with a good resilience.

Technical Informations

Application Advice/Typical Applications

LIPOLAN® F2820F  remains mechanically stable when complying with the storage conditions given below.

Vulcanised latex foam made using LIPOLAN® F 2820F exhibits a high resilience. It has a very soft character and excellent mechanical properties. Both tensile strength and elongation at break of the vulcanised latex allow a great flexibility of mould design. LIPOLAN® F 2820F has to be vulcanised in a similar manner to natural rubber latex. In order to achieve an optimal quality level, rubber chemicals must be adapted to the compound formulation and manufacturing conditions. LIPOLAN® F 2820F suits to Dunlop, Talalay and non-gel process.

Shipping and Storage

LIPOLAN® F 2820F is delivered in road tankers. Shipment in 1 ton containers (IBC) is also possible.
LIPOLAN® F 2820F must permanently be protected against frost. The ideal storage temperature range is between + 5°C and + 30 °C. Exposure to temperatures above + 30 °C or to direct sunlight for extended periods of time has to be avoided. Temperatures never must exceed + 40 °C.
Complying with these storage conditions the dispersion has a shelf life of 6 months after delivery, when kept permanently and tightly closed. The pH value of the dispersion may decrease due to absorption of carbon dioxide from air. Dispersions having a pH lower than 10 should be readjusted to the initial value using an aqueous KOH solution of 5 % concentration. Material in broached containers should be used as soon as possible. In some cases, a slight drying of the surface or some cream formation cannot be excluded. Therefore the dispersion or the compound made of it should be stirred or mixed before use.
