Beside unreinforced PEEK, there are also several mainstream modified PEEK Types like PEEK supplemented with PTFE and also PEEK modified with Graphite, Carbonfiber and PTFE. There is also PEEK reinforced with Glass or Carbonfibre only. BIEGLO offers selected compounds based on recycled PEEK to offer a low-cost alternative for less-critical circumstances.
Reinforced PEEK is mostly used to increase it's excellent properties. PEEK reinforced with PTFE increases it's self-lubricating properties. PEEK filled with Carbon fiber reduces it's thermal expansion and it's tensile elongation, but increases it's tensile strength and bending strength.
Most common compounded PEEK-types are:
PEEK Mod (PTFE/Graphite/CF);
PEEK - PTFE;
