High‑Performance PA Compounds
Our PA Compound Lines
Key Properties:
High Strength and Toughness
Combines excellent tensile strength, stiffness, and impact resistance—ideal for structural and load-bearing parts under dynamic or cyclic stress.
Good Thermal and Dimensional Stability
Withstands continuous use at 100–120°C (higher with reinforcement), while maintaining low warpage and precision molding capability.
Excellent Wear and Chemical Resistance
Offers low friction, high wear resistance, and strong resistance to oils, fuels, solvents, and hydrolysis (in modified grades).
Versatile and Easily Modified
Adaptable with glass fiber, carbon fiber, flame retardants, UV/impact stabilizers, and pigments—suitable for a wide range of applications and processing needs.
Key Properties:
Superior Mechanical Strength and Rigidity
Higher crystallinity gives PA66 greater tensile strength and stiffness than PA6—ideal for demanding structural parts.
Excellent Heat and Wear Resistance
Offers higher heat distortion temperature (up to 130°C+) and outstanding abrasion resistance for moving or high-temperature environments.
Good Chemical and Oil Resistance
Resistant to many automotive fluids, greases, fuels, and solvents—widely used in under-the-hood and industrial components.
Stable Processing and Modifiability
Suitable for fast-cycle molding, with excellent flow and reinforcement compatibility; easily modified with GF, FR, impact, UV, and coloring systems.
Key Properties:
Exceptional Thermal Resistance
High heat deflection temperature (HDT > 260°C), excellent dimensional stability under long-term heat exposure—ideal for metal-replacement in high-temperature environments.
Superior Mechanical Strength and Stiffness
Maintains strength, rigidity, and creep resistance at elevated temperatures; often reinforced with glass or carbon fiber for enhanced performance.
Outstanding Chemical and Hydrolysis Resistance
Excellent resistance to automotive fluids, fuels, coolants, and aggressive chemicals—even under high heat and pressure.
Precision Molding and Surface Quality
Allows for thin-wall, high-precision parts with excellent surface finish—widely used in electronic connectors, automotive engine components, and fluid system parts

Application
Product Advantage
Unmatched Mechanical Performance and Stability
Exceptional Strength & Stiffness
Our GF‑reinforced PA66 and PPA compounds achieve tensile strengths up to 200 MPa and flexural moduli over 12 GPa, ensuring load‑bearing capacity in structural components. The high fiber content suppresses creep and improves fatigue resistance, critical for under‑hood parts and industrial machinery. Precise molding reduces shrinkage and warpage, guaranteeing tight dimensional tolerances and minimal scrap rates.
Broad Thermal & Environmental Resistance
Orinko’s PPA and UV‑resistant PA1010/1012 grades maintain mechanical integrity at temperatures exceeding 180 °C and resist hydrolysis in humid conditions. Flame‑retardant UL94 V‑0 variants deliver reliable fire safety for electrical applications. Low‑moisture PA610/612 minimizes dimensional drift, making them ideal for outdoor and automotive sealing applications where stability and longevity are paramount.
Common Questions
Q1: What makes Orinko PA compounds unique?
A1: Orinko’s PA6/PA66/PPA compounds combine certified IATF 16949 quality, tailored glass‑fiber and flame‑retardant grades, and low‑moisture formulations for unmatched performance across industries.
Q2: Which PA grade for under‑hood applications?
A2: Choose glass‑fiber reinforced PA66 or PPA grades; they offer high strength, thermal stability up to 180 °C, and creep resistance required for engine components.
Q3: Can PA610/612 withstand humidity?
A3: Yes, low‑moisture PA610/612 resins exhibit minimal water absorption, ensuring dimensional stability and reliable sealing performance in humid or outdoor environments.
