What is an incorrect storage condition for rubber?

Prolonged exposure to heat is detrimental to rubber as it accelerates degradation processes such as oxidation and embrittlement, leading to loss of elasticity and flexibility. Heat can cause the rubber to harden, crack, or develop surface deformities, ultimately affecting its performance and longevity.

In contrast, keeping rubber in cool environments helps maintain its physical properties and extends its usable life, preserving the material's integrity. Storing rubber away from direct sunlight is also critical because ultraviolet (UV) radiation can cause rubber to break down, leading to surface cracks and loss of strength. Additionally, maintaining optimal humidity levels is important to prevent the rubber from absorbing moisture, which can influence its performance and potential mold growth.
