ELASTOSIL® R plus 4070/30 MH
ELASTOSIL® R plus 4070/30 MH is an addition-curing, self-bonding one-component high consistency silicone rubber for the manufacture of molded articles.
ELASTOSIL® R plus 4070/30 MH is a self-adhesive grade which adheres to various plastic substrates (e.g. PA, PBT) and metals without tack formation to the mold. The bonding properties can be improved by a post-curing process (e.g. one hour at 100 °C) or by a longer storage at room temperature. Because of the individual surface properties each
substrate must be tested before serial production. The vulcanizates are transparent and noted for good mechanical and electrical properties. Thanks to addition cure, the vulcanization reaction is significantly faster compared to peroxide curing materials. No peroxide decomposition products are formed during vulcanization.
At service temperatures above approx. 180 °C the addition of heat stabilizers is recommended. Further information about an improvement of the heat stability by use of specific ELASTOSIL® AUX Heat Stabilizers can be obtained from the Technical Information Sheet "ELASTOSIL® AUX Stabilizers H" or the latest edition of our brochures.

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".
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.
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.
