Depending on method of product sterilization, EPDM is used on products of 10 pH and higher. Also used with general purpose IV, fatty emulsion and hyper-alimentation solutions. Silicones A high quality, low extractable elastomer intended for applications requiring resistance to high temperatures or multiple steam sterilization cycles. Commonly used to package soft contact lenses or attendant solutions. A synthetic poly elastomer intended for use with animal, vegetable and mineral oil solutions.
Nitriles have a high resistance to some solvents.
Natural Rubber A general purpose elastomer intended primarily for aqueous liquid fill products in the 4.0 - 7.5 pH range. Its principle advantage is its resealability in multi-dose applications. Thermoplastic Elastomers Used in some of our custom manufactured applications, thermoplastic elastomers perform like rubber, do not require vulcanization and can be precision molded to exceptionally close tolerances. Advantages include cleanliness, low extractables and the capacity for fully automated manufacturing. To read about Sleeve Stoppers and Flashback Bulbs, click previous.
