Thermoplastics banner h2

H2 proven plastics

We continually strive to offer innovative solutions through our vast experience in thermoplastic engineering backed‑up by robust testing.

Our range of Devlon materials is amongst the toughest and hardest-wearing thermoplastics and our extensive working relationship with our customers has allowed us to develop a portfolio suited to the variety of applications experienced within the valve industry. Within our range we can offer materials that are:

  • Tested and qualified for hydrogen service
  • Suited for high temperature and high pressure applications
  • Provide lower frictional losses than PEEK products
  • Offer exceptional resistance to wear and abrasion
  • Are sufficiently conformable to seal in low pressure valve applications
  • Provide total assurance of product quality and traceability with Positive Material Identification (PMI) technology
