Cepure 3000 Silicone Septa Technical Datasheet

Product Description

The CP3000 family of products serves many applications, from environmental bottle liners to LC/GC vial septa. CP3000 can be supplied as loose septa, press fit into closures, or mechanically bonded into place (without adhesives or primers). Only the highest quality silicone elastomers are used to ensure proper re-sealability and to minimize coring. Various film types, such as PTFE and FEP, may be used to maximize chemical resistance.
