Material Properties: Nylon 66 vs Nylon 12 vs Stainless Steel
Side-by-side comparison of mechanical, thermal, and chemical properties for all cable tie materials. Includes PA66, PA12, LSZH, PEEK, SS304, and SS316.
Why Material Choice Matters
The right material depends on: operating temperature range, UV exposure, chemical environment, mechanical load, fire safety requirements, and budget. Choosing wrong can mean premature failure in the field.
Nylon 66 — The Workhorse
Best balance of strength, cost, and availability. 80% of all cable tie applications use PA66. Heat-stabilized variants extend the upper temperature limit. UV-stabilized variants add outdoor durability.
Specialty Materials
PA12: superior UV + cold weather. LSZH: fire safety for enclosed spaces. PEEK: extreme temperature + chemical resistance (aerospace, semiconductor). SS304/316: ultimate strength + temperature + chemical resistance.

FAQ
Which material has the best tensile strength?
Stainless steel 304/316 offers the highest tensile strength (515 MPa). Among plastics, PEEK is strongest (100 MPa), followed by PA66 (82 MPa). See our Tensile Strength Guide for detailed data by tie size.
When should I use PA12 instead of UV-stabilized PA66?
Use PA12 when you need both UV resistance AND cold temperature performance (below -20C). UV-stabilized PA66 is sufficient for most outdoor applications above -20C and costs less.
