Wire and cable general and tensile properties, electrical, thermal, and flammability values

In thermal aging tests at up to 130°C for 1,000 hours, products made with OnColor durable orange nylon colorants achieved improved results compared to similar orange colorants against long-term fading resistance while meeting customer requirements of no migration and low volatility.

Broadly recognized for their chemical inertness, thermal stability, hydrophobicity, low surface energy, and low coefficient of friction (CoF), making them useful in many applications.

They also can pass comprehensive xenon and environmental aging tests and show no visual defects, deformation, or stickiness after short-term (6 hours at 100°C) and long-term (500 hours at 90°C) thermal aging.
