ELASTOSIL® R plus 4081/55 MH

ELASTOSIL® R plus 4081/55 MH is an addition-cure, one-component high consistency silicone rubber for the manufacturing of molded articles. Cured articles are of a white color and show good thermal conductivity in combination with excellent electrical insulation and good mechanical properties.


Properties

ELASTOSIL® R plus 4081/55 MH is a fast-curing silicone rubber exhibiting good thermal conductivity and good mechanical properties. Thanks to addition cure, the vulcanization reaction is significantly faster compared to peroxide curing materials. No peroxide decomposition products are formed during vulcanization.

Due to the high filler loading the cured rubber exhibit a white color.

Post-curing above 150 °C leads to a deterioration of the compression set.

ELASTOSIL® R plus 4081/55 MH is particularly suited for processing on a silicone rubber injection molding machine.

CAUTION! Due to the high filler loading the ELASTOSIL® R plus 4081/55 MH shows a significant degree of abrasion. Therefore, we recommend contacting your injection molding machine and dosing system manufacturer as well as your toolmaker.

CAUTION! Danger of deactivation! The platinum catalyst can be deactivated by e.g. amines or sulfur compounds. For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".

Packaging

This product is available in 20 kg and 540 kg cardboard packaging.
Special delivery forms are possible but depend on several technical and commercial aspects. Please contact your local sales manager in such cases.

Storage

Please store the cardboard boxes in a dry and cool place. Once opened, cardboard boxes should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
