TPX® functional polymer remains strong and transparent after repeated steam sterilisation

Huntingdon ... 7 January 2014 ... TPX® polymethylpentene is a lightweight, transparent, semi-crystalline material with outstanding resistance to both steam sterilisation and a wide range of chemicals. Unlike some polymeric materials that discolor or embrittle after just a few cycles in an autoclave, TPX® remains transparent and strong. Items made with this exceptional polymer can be reused many times, promoting reuse rather than recycling and contributing to greater sustainability.

Characteristics of TPX® include:
• Low density
• Resistance to steam and chemicals
• Does not absorb water
• Visible light transmission ~92-94%
• Low refractive index
• Nonstick properties

The numerous benefits of TPX® make it ideal for use in food containers, sterilisation cases, laboratory equipment, LED moulds, etc. TPX® also has excellent UV transmission characteristics, making it useful in UV sterilisation equipment.

TPX® is available in film, sheet, rod and granule form from Goodfellow, a leading supplier of polymers, metals, ceramics and composites for research and industry. For more information, contact the company on 0800 731 4653 (UK) or +44 1480 424 800,, or visit visit
