General Engineering Plastics (POM / PA / PE)

DMR Seals holds an extensive range of semi-finished general engineering plastic materials in stock to enable rapid turnaround of finished products to our customers.

General engineering plastics such as Polyacetal (POM), Polyamide (PA, Nylon) and others can offer many advantages over metallic materials when chosen correctly, most materials have excellent mechanical and thermal properties and normally offer a significant reduction in weight and cost in comparison. Listed below are just a few of the advantages that can be found using these materials in place of metals:

  • Reduction in weight
  • Reduced cost
  • Excellent wear properties
  • Thermal insulation

DMR Seals understands that choosing the correct general engineering plastic for your application can sometimes be tough. By taking careful consideration of your application conditions, such as temperature, load, speed and chemical compatibility, this process can be made much simpler and get you the correct result.

Please contact our technical team should you require any help choosing the correct material for your application.
