Disclaimer

All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence.

These grades are particularly suitable for the economical production of large series of injection-molded articles.

 

Although most silicone rubbers show good resistance to boiling water, they degrade rapidly when subjected to superheated steam at temperatures of 150 °C and above (corresponding to 6 bar pressure). ELASTOSIL® LR 3020/60 A/B shows significantly improved performance under such conditions, especially with respect to the long term compression set.


Parts made from ELASTOSIL® LR 3020/60 A/B can be used for technical applications. These articles are also suitable for use in conjunction with foodstuffs.

 

Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances.

 

The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer.

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 pail and 200 kg drum kits.

Storage

Once opened, containers 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.
