Peek Carbon: a semi-crystalline polymer developed on the basis of the better-known Peek and compatible with 3ntr’s Spectral 30 system, 3ntr’s Peek Carbon is filled with as much as 30% carbon fibre to meet the demands of demanding markets such as aerospace, automotive and oil gas. A high chemical resistance that makes it almost unassailable, together with excellent tensile and flexural mechanical properties, make it a perfect upgrade to the more traditional Peek.
