Marprene is Watson-Marlow Bredel's exclusive thermoplastic elastomer. Proven superior in applications where it is chemically compatible, it is our most often recommended tubing material. Marprene has a wide chemical compatibility and is highly resistant to oxidising agents such as ozone, peroxides and hypochlorite.
Marprene is also opaque to both visible and ultra-violet light, and maintains low permeability to gases such as oxygen, carbon dioxide and nitrogen.
