🎭 Elastosil® FX-Series – Silicones for SFX & Prosthetics
The FX series is specially developed for special effects, cosplay, LARP, and prosthetics: extremely stretchable and available with additives for customization.
What Wacker declares about skin contact. For FX 10, FX 20, FX 28 and FX Gel 30, Wacker issues a Statement on Compatibility to Skin. It says in so many words that no toxicological tests have been carried out on these products themselves, but that irritation, sensitization and cytotoxicity tests to ISO 10993 have been performed on other two-component addition-curing silicones of similar base materials, showing no adverse effects. Based on that analogy and the toxicological properties of the ingredients, Wacker does not expect irritation or sensitization on contact with intact skin. Wacker adds that the end application must be in line with the WACKER SILICONES HEALTH CARE POLICY of September 2019, and that responsibility for the finished article rests with whoever places it on the market.
So this is an expectation based on analogy — not a test report on the product itself, and not a certification, because no such certification exists at raw material level. For mucosal contact, broken skin or contact for more than 30 days the Health Care Policy applies; talk to us first. The processor remains responsible for correct mixing, full cure, post-cure and their own assessment of the finished article. We send the statements on request.
Food contact. The PCS for FX 10, FX 20, FX 28 and FX Gel 30 state food contact conformity under EC 1935/2004, BfR XV Silicones (volatiles max 0.5 %, extractables max 0.5 %, platinum residue max 50 mg/kg in the finished article), the French Arrêté of 25 November 1992, Spanish Real Decreto 847/2011, Swiss Ordinance SR 817.023.21, Chinese standards GB 9685-2016, GB 4806.16-2025 and GB 4806.1-2016, and ANVISA/Mercosur. For the United States Wacker gives no blanket statement — a food contact statement is available there on request. Unlike the Vario series, the FX PCS therefore contains no reference to FDA 21 CFR.
