What is the primary cause of cracking and cutting in rubber gloves?

The primary cause of cracking and cutting in rubber gloves is related to prolonged folding or compressing. When rubber gloves are consistently folded or compressed for extended periods, the material experiences stress and can develop micro-cracks over time. This physical deformation can weaken the rubber structure, making it more susceptible to damage during use.

In this context, rubber is best maintained when stored properly, avoiding unnecessary bends and pressure, as these factors contribute to the deterioration of the material's integrity. Maintaining the gloves in a relaxed state helps to preserve their flexibility and strength, reducing the likelihood of cracks and cuts during their intended use.

Other factors can certainly impact rubber gloves' lifespan and usability, such as ozone damage and chemical attacks, which are also valid concerns. However, in terms of mechanical stress and physical wear, the prolonged folding or compressing stands out as the most direct cause of the cracking and cutting observed in rubber gloves.
