Duroplastic composite materials for industrial applications. What they are and what they can do.

Duroplastic materials stand out primarily due to their high mechanical strength. In this respect, they outdo thermoplastic materials such as PEEK, PA, POM or PTFE many times over.

Why is this?
Thermoplastics are not cross-linked. The lack of a transverse linking means that if heat is introduced, for example, the linkings shift against one another. When temperatures increase, these materials change their shape accordingly easily – they 'flow'. Duroplastics, on the other hand, enjoy much denser cross-linking, as the individual strings are held together by transverse connections. Their shape remains intact even if a material reaches its boundary temperature. Moreover, the loss of mass is significantly smaller.


In summary, these are the benefits:

  • High chemical resistance
  • Lower thermal expansion coefficient
  • Low setting behaviour
  • Improved electrical properties (depending on the material composition)
  • Lower heat conductivity
  • More precise tolerances can be realised for components
