Will the rubber soften over time, or is it designed to retain its firmness?Updated 7 months ago

An FKM rubber strap is designed to retain its firmness and structural integrity over time. Unlike traditional rubber, which may soften or degrade, FKM rubber is more durable and resistant to wear, maintaining its form and flexibility even with daily use.

Why It Retains Firmness:

Material Composition: FKM (fluoroelastomer) rubber is engineered to be both flexible and stable, meaning it doesn’t soften significantly with use. Its unique molecular structure provides excellent resilience, allowing it to keep its shape while conforming to the wrist comfortably.

Wear Resistance: FKM rubber is highly resistant to environmental factors like UV rays, water, and chemicals, which often cause other rubbers to degrade or soften. This quality ensures that the strap remains relatively firm over time, even with exposure to heat and moisture.

While FKM rubber will conform slightly to the wrist for added comfort, it generally retains its firmness and original shape, providing lasting durability and a consistent feel throughout its lifespan.
