PA 12 (Nylon PA12)
Overview:
PA 12 (Nylon PA12) is a high performance engineering thermoplastic derived from laurolactam. Its long hydrocarbon chain delivers the lowest moisture absorption rate among commercial nylons, resulting in excellent dimensional stability across varying environments. PA 12 offers outstanding impact resistance, including at temperatures as low as -40°C, along with strong resistance to fuels, oils, greases, and hydrocarbons. The material is well suited for demanding functional components that require durability, chemical resistance, and long term dimensional accuracy.
Applications:
PA 12 is widely used for functional prototypes and end use components in automotive, aerospace, industrial, medical, and consumer applications. Common applications include housings, brackets, clips, ducts, fluid handling components, snap fit assemblies, and lightweight parts exposed to mechanical stress, vibration, or chemically aggressive environments. Its balance of toughness, dimensional stability, and chemical resistance makes it a reliable choice for both production and engineering validation.

PA 11 Ductile Nylon
Overview:
PA11 Ductile Nylon is a bio based engineering thermoplastic derived from castor oil and designed for applications requiring exceptional toughness, ductility, and impact resistance. Compared to standard PA12 materials, PA11 offers greater elongation at break, improved fatigue resistance, and superior performance under repeated loading or flexing conditions. The material maintains strong chemical resistance and dimensional stability while remaining lightweight and durable in demanding environments. Its ability to absorb impact without cracking makes it well suited for functional components exposed to vibration, snap fit loading, or dynamic mechanical stress.
Applications:
PA11 Ductile Nylon is commonly used for durable functional prototypes and end use production parts in aerospace, automotive, industrial, robotics, medical, and consumer product applications. Typical applications include clips, brackets, enclosures, living hinges, orthotics, ducts, protective covers, wearable components, and parts subjected to repeated stress or impact loading. Its high ductility and fatigue resistance make it especially valuable for components that require flexibility, long term durability, and reliable mechanical performance in real world operating conditions.

Good/Fair (Rating B):
Long-term exposure to elevated humidity, thermal cycling, or chemically aggressive industrial environments may gradually degrade mechanical properties. (recommended controlled environmental conditions of 50-70% relative humidity for stable performance.)
Poor (Rating C):
Strong mineral acids (hydrochloric acid, sulfuric acid), chlorinated hydrocarbons, phenols, and strong oxidizing acids can cause swelling, softening, or material degradation.
PA11 generally provides slightly better chemical and environmental stress-crack resistance than PA12, especially in dynamic or repeated-load applications.

TPA Flexible Elastomer
THIS INFORMATINO MUST BE UPDATED WITH IA3D’S TPA FE… DEPENDING ON MANUFACTURER
Overview:
TPA Flexible Elastomer is a high performance thermoplastic elastomer designed for additive manufacturing applications that require flexibility, resilience, and long term durability. Combining rubber like elasticity with the processability of thermoplastics, TPA materials offer excellent energy absorption, impact resistance, and repeated flex performance while maintaining good dimensional stability and chemical resistance. The material is well suited for parts exposed to vibration, compression, cyclic loading, or frequent handling. Its soft touch surface and elastic recovery make it ideal for functional components that require both flexibility and toughness.
Applications:
TPA Flexible Elastomer is commonly used for seals, gaskets, bellows, grips, vibration dampers, protective covers, tubing, orthotics, wearable products, and flexible industrial components. The material is widely used in automotive, industrial, robotics, medical, and consumer applications where shock absorption, flexibility, and durability are critical. Its ability to withstand repeated bending and compression cycles makes it especially valuable for end use parts exposed to dynamic mechanical loading and harsh operating environments.

Excellent (Rating A):
Oils, greases, hydraulic fluids, fuels, aliphatic hydrocarbons, and many industrial lubricants. TPA elastomers also demonstrate strong resistance to abrasion, vibration, and repeated flexing under demanding operating conditions.
Good/Fair (Rating B):
Alcohols, weak acids, diluted alkalis, and moderate exposure to water based cleaning agents. Extended exposure to UV light, elevated humidity, or high temperatures may gradually reduce elasticity over time.
Poor (Rating C):
Strong acids, ketones, chlorinated solvents, aromatic hydrocarbons, and aggressive oxidizing chemicals, which can cause swelling, softening, or degradation of elastomeric properties.
TPA Flexible Elastomers are best suited for applications requiring flexibility, impact absorption, and repeated mechanical cycling rather than high structural rigidity or elevated temperature resistance.
