What’s the Heat Limit for Heat-Resistant Cable Ties: PA66HS vs. PA46


The question of “What‘s the maximum temperature heat-resistant cable ties can withstand?” is not purely academic; it bears on manufacturing efficiency, equipment safety, and even the smooth operation of an entire production line. In sectors like chemical engineering, aerospace, and automotive manufacturing, the high-temperature resistance of nylon cable ties is critical. This article by NIKE Plastic will guide you through what you need to know about heat-resistant cable ties, their attributes, and their industrial applications.

The Rise of Heat-Resistant Cable Tie

Since their debut in 1958, nylon cable ties have been a mainstay in industrial, commercial, and domestic applications, serving as convenient tools for bundling, supporting, and organizing cables and tubes. However, advancements in industrial operations and improvements in high-performance plastic materials have increased the demand for heat-resistant cable ties.

Materials for Heat-Resistant Cable Ties

1. Heat-Stabilized Nylon 66 (PA66HS)

Definition: PA66HS represents a specific variant of Nylon 66 (PA66), with ‘HS’ usually denoting ‘Heat Stabilized.’

Characteristics: This type maintains its mechanical performance and dimensional stability at elevated temperatures, making it more reliable and durable. Standard PA66HS can function at temperatures up to 180°C.

Applications: Automotive, electronics, and industrial equipment.

2. Polyamide 46 (Nylon 46)

Definition: PA46 stands for Nylon 46, a unique type of nylon plastic primarily made from dimer diamine and adipic acid.

Characteristics: PA46 offers excellent mechanical properties and chemical stability at high temperatures, capable of working between 250°C to 280°C.

Applications: Automotive, electronics, and aerospace.

The Differences between PA66HS and PA46, and Which Should You Choose

Melting PointApprox. 260-270°CApprox. 290-315°CPA46 has a higher melting point, suitable for higher temperature applications
Tensile StrengthApprox. 75-85 MPaApprox. 90-100 MPaPA46 generally has a higher tensile strength
Impact StrengthApprox. 7-10 kJ/m²Approx. 6-9 kJ/m²Both have similar impact strength
Wear ResistanceModerateExcellentPA46 has relatively better wear resistance
Water AbsorptionApprox. 2-3%Approx. 1.2-1.5%PA46 has a lower water absorption rate
CostLowerHigherCosts can vary between different manufacturers
The differences between PAHS & PA46

Overall, PA66HS is commonly used in general engineering applications requiring improved heat resistance (up to 180℃), while PA46 is suited for more specialized and demanding applications that require higher mechanical performance and can withstand even higher working temperatures (up to 280℃).


The maximum temperature a cable tie can withstand depends on its material. While regular nylon ties cap out at 85℃, heat-stabilized PA66 can function up to 180℃, and PA46 can work in temperatures as high as 280℃.

Choosing the right heat-resistant cable tie is a technical challenge and a business decision. Partnering with a professional cable tie manufacturer like NIKE Plastic not only assures the quality and performance of the product but also provides comprehensive support and services throughout the project’s implementation.
