PA6 (Nylon 6) with 30% glass fiber reinforcement is the workhorse engineering thermoplastic for structural applications below 120°C. At a fraction of the cost of PEEK or PPS, it offers 170 MPa tensile strength with excellent toughness, fatigue resistance, and chemical resistance to hydrocarbons. It is the default material for automotive engine covers, intake manifolds, power tool housings, and industrial gear components.

Frequently Asked Questions
What are the moisture absorption limitations of PA6 GF30?
PA6 absorbs 2.5-3.0% moisture at equilibrium (50% RH), which reduces tensile strength by ~15% and increases impact resistance. For dimensionally stable applications in humid environments, consider PA66 or PPS. Nylon parts must be conditioned after molding to achieve stable dimensions — as-molded parts are dry and will expand as they absorb ambient moisture over 24-48 hours.
