Specific properties

PEEK GF30 / PEEK GF30 LSG This quality has been reinforced with 30% fiberglass, which makes it stiffer and with very low shrinkage. It is thus ideal for structural parts that must maintain their strength under high temperatures. PEEK GF30 is also available in Life Science Grade: LSG.
