Material Overview
What is PA12 Polyamide 12 (Nylon 12) — Sheet & Rod?
PA12 material (polyamide 12) is an extruded nylon plastic distinguished by its low moisture absorption relative to other polyamide grades. Lower moisture uptake means components hold tighter dimensional tolerances in humid or variable environments — a critical advantage for precision gears, fittings, housings, and machined parts where stability is required over the product's service life. Ready Plastics stocks PA12 in sheet and rod for direct machining.
PA12 provides good mechanical strength, solid impact resistance, and flexibility suited to parts exposed to vibration or cyclic loading. Its chemical resistance extends to fuels, hydraulic fluids, and a range of solvents, which makes it a reliable choice for fittings and connectors in fluid-handling assemblies and under-hood automotive components. The combination of stability, toughness, and chemical resistance gives PA12 a well-rounded performance profile for precision industrial use.
Enhanced grade. Where even higher stiffness is required, Ready Plastics offers PA12 CF50 — a 50% carbon-fiber-reinforced variant that dramatically increases rigidity and load-bearing performance while maintaining low weight. CF50 is the preferred choice when dimensional stability and structural stiffness are the primary design drivers.
Choosing within the nylon family. Within the broader nylon material lineup, PA12 sits between PA6 (higher strength, higher moisture absorption) and an optimal low-moisture balance. When maximum strength matters more than moisture stability, PA66 is the step up. For the lowest moisture absorption in the family, PA12 leads extruded grades; PA612 offers an intermediate position with a balance of strength and moisture performance.
Frequently Asked Questions
PA12 Polyamide 12 (Nylon 12) — Sheet & Rod, answered
What is PA12 material?
PA12 (polyamide 12) is an extruded nylon plastic known for its low moisture absorption, excellent dimensional stability, and good chemical resistance. These properties make it well suited for precision components — gears, bushings, fittings, housings — that must maintain tight tolerances in humid or variable conditions.
What is the difference between PA12 and PA6?
PA12 absorbs significantly less moisture than PA6, giving it better dimensional stability and more consistent mechanical properties in wet or humid environments. PA6 offers higher tensile strength and better wear resistance in dry conditions. Choose PA12 when tolerance stability and chemical resistance to fuels or fluids are the primary requirements; choose PA6 when maximum strength and impact toughness are the priority.
What makes PA12 suitable for fuel system components?
PA12 offers good resistance to fuels, hydraulic fluids, and many solvents, combined with low moisture absorption and dimensional stability. These characteristics support reliable long-term performance in fuel lines, fittings, connectors, and under-hood automotive assemblies.
What shapes does Ready Plastics stock in PA12?
Ready Plastics stocks PA12 in sheet and rod. For current dimensions and availability, contact Ready Plastics directly or request a cut-to-size quote. A carbon-fiber-reinforced variant, PA12 CF50, is also available for applications requiring higher stiffness.
Is PA12 the same as PA12 CF50?
No. PA12 is the unreinforced base grade offering balanced toughness, low moisture absorption, and good chemical resistance. PA12 CF50 incorporates 50% carbon fiber reinforcement to significantly increase stiffness and load-bearing strength while keeping weight low. PA12 CF50 is chosen when structural rigidity is the primary requirement.
