| Product description: Liquid silicone rubber of the SILPURAN® 6700 series is a paste-like, easily-pigmentable two-component compound with a very short curing time and good mechanical and electrical properties. Vulcanizates are noted for their self-adhesive properties to various substrates. Properties: SILPURAN® 6700/40 A/B meets selected test requirements of ISO 10993 and United States Pharmacopoeia (USP) Class VI. 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. Special features: SILPURAN® 6700/40 A/B is a primerless selfbonding grade that adheres to various thermoplasts (e.g. PA, PBT) and metals. The bonding is improved by an ageing 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 mass production. If necessary one has to check the development of adhesive properties over time and/or in an environment relevant to the application. Application: SILPURAN® 6700/40 A/B is particularly suitable for the economical production of large series of injection-moulded articles. SILPURAN® 6700/40 A/B is designed for medical and pharmaceutical applications including implantation for < 30 days. Information provided by Wacker Chemie AG. |
