By understanding the limitations and proper usage guidelines for each type of cable tie, you can ensure optimal performance, safety, and longevity in your applications.

Mistakes to Avoid with PEEK Cable Ties

1. Overexposure to extreme temperatures: Although PEEK cable ties can withstand high temperatures up to 500°F (260°C), it's crucial not to exceed this limit. Exposing PEEK ties to temperatures beyond their rated capacity can lead to material degradation and failure.
2. Improper installation in high-stress areas: While PEEK cable ties offer excellent strength and durability, they should not be used as a replacement for proper fastening methods in high-stress or load-bearing applications. Always follow the manufacturer's guidelines and use appropriate fasteners when necessary.
3. Neglecting chemical compatibility: PEEK cable ties are resistant to many chemicals, but it's essential to verify their compatibility with the specific chemicals present in your application. Some highly aggressive chemicals or prolonged exposure may still cause material degradation.
4. Overtightening the ties: Although PEEK cable ties are strong, overtightening them can lead to stress on the cable insulation or even damage to the tie itself. Use the appropriate tensioning tool and follow the manufacturer's recommended tension settings to avoid overtightening.

Mistakes to Avoid with Polypropylene Cable Ties

1. Using in high-temperature environments: Polypropylene cable ties are not suitable for applications with prolonged exposure to high temperatures above 185°F (85°C). Using them in such environments can cause the ties to soften, lose their strength, or even melt, compromising the integrity of your cable installation.
2. Exposure to harsh chemicals: While polypropylene ties offer some chemical resistance, they are not designed to withstand exposure to aggressive chemicals, solvents, or fuels. Using polypropylene ties in chemically harsh environments can lead to material degradation, brittleness, and failure.
3. Outdoor use without UV protection: Standard polypropylene cable ties may not have built-in UV resistance. Prolonged exposure to sunlight and UV radiation can cause the ties to become brittle and lose their strength over time. If outdoor use is required, opt for UV-stabilized polypropylene ties specifically designed for such applications.
4. Exceeding the rated tensile strength: Each polypropylene cable tie has a specific tensile strength rating. Attempting to bundle or secure cables beyond the tie's rated strength can lead to overstressing and potential breakage. Always choose the appropriate tie size and strength for your application and avoid overloading the ties.
