ELASTOSIL® R plus 4305/60 S

ELASTOSIL® R plus 4305/60 S is an addition-curing, two-component high consistency silicone rubber for the manufacture of extruded articles. Cured articles are of excellent transparency and exhibit good to very good mechanical properties.



特性

ELASTOSIL® R plus 4305/60 S is a fast curing silicone rubber exhibiting good to very 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.

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.

所提供之所有信息均基于我们当前所掌握的知识。尽管如此,我们不对其作任何担保、也不承担任何责任,并且保留在任何时候进行技术变更的权利。购买方应在预测试中对所提供之信息以及产品在既定应用中的适应性进行检查。任何时候都必须以合同条款与条件为准。此外,本免责申明还适用于与第三方权利有关之事宜,尤其是在德国境外。

ELASTOSIL® R plus 4305/60 S is suited for the manufacture of extruded articles.

Properly cured and post-cured vulcanizates of ELASTOSIL® R plus 4305/60 S can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA 21 CFR §177.2600 "Rubber Articles Intended for Repeated Use" considering any given limitations on extractable and volatile substances.

ELASTOSIL® R plus 4305 series may not be cured with peroxides but only with the platinum catalyst batch ELASTOSIL® AUX Batch PT 1. ELASTOSIL® R plus 4305/60 and ELASTOSIL® AUX Batch PT 1 are mixed homogeneously on a roll mill in a ratio of 100:1.5. A higher catalyst dosage results in a faster curing but a reduced pot life. Care must be taken to keep the compound cool during mixing. A homogeneous incorporation is a must, but the temperature of the rubber should not exceed 30 °C, otherwise there is a risk of scorch.
The cross linking reaction starts as soon as ELASTOSIL® AUX Batch PT 1 has been added. The rate and degree of crosslinking is dependent on storage time and temperature. At 23 °C the pot life is approximately 24 h. This can be extended by storing the catalyzed mixture at lower temperature.
For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".

包装

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.

储存

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.
