Materials & Performance

Why does the moisture absorption rate of cable ties affect their service life?

Polyamide (Nylon) is hygroscopic. Once it absorbs moisture, it may swell dimensionally, lose rigidity, change in tensile strength and lose some of its holding capability. In long-term use in high-humidity or salt-spray environments, material stability directly affects how reliably the cable bundle is secured, so moisture absorption rate is one of the key factors when choosing industrial-grade cable ties.
