The material PEEK-30GF is a variant of PEEK modified with 30 % glass fibres. This modification significantly increases the surface hardness and heat deflection temperature compared to the already high values of the unreinforced standard type. The coefficient of linear expansion can also be reduced by approx. 25 %.
