• Molded Parts

Application details

These grades are particularly suitable for the economical production of large series of injection moulded articles with excellent optical transparency. Parts made from LUMISIL LR 7601/70 A/B can be used for technical applications. These articles are also suitable for use in conjunction with foodstuffs. The following studies were performed on vulcanizates of LUMISILLR 7601/70 A/B according to ISO 10993: 

- Cytotoxicity (ISO 10993-5)

- Sensitation LLNA (ISO 10993-10)

- Pyrogenicity (ISO 10993-11)

The following studies were performed on vulcanizates of LUMISILLR 7601/70 according to USP class VI: 

- Acute systemic toxicity

- Intracutaneous toxicity

- Implantation test

No adverse effects have been detected at any of the studies performed. A master file has been filed with the U.S. Food and Drug Administration. An authorization to reference the master file will be available upon request. 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. Please note that the product contains low levels (<0.1%) of residual hydocarbons which have to be removed from the finished food contact article.
