the climate: humidity or lack there of.
When left out in the sun rubber will loose some of its elasticity or crack, the ink will lose some color, and paper will be bleached or become whiter. This occurs because of the action of the ultraviolet light of the sun.
Difference Between Natural Rubber And Vulcanized RubberNatural rubber Vulcanized rubber(1) Natural rubber is soft and sticky Vulcanized rubber is hard and non-sticky. (2) It has low tensile strength. It has high tensile strength. (3) It has low elasticity. It has high elasticity. (4) It can be used over a narrow range of temperature (from 10° to 60°C). It can be used over a wide range of temperature (–40° to 100°C). (5) It has low wear and tear resistance. It has high wear and tear resistance. (6) It is soluble in solvents like ether, carbon, tetrachloride, petrol, etc. It is insoluble in all the common solvents.
THE NORTH part, is Brazil's largest and most rapidly devoloping subregion. It was home to the rubber boom more than a century ago.
Vulcanization is the process by which rubber molecules (polymers or macromolecules made of repeating units or monomers called isoprene) are cross-linked with each other by heating the liquid rubber with sulfur. Cross-linking increases the elasticity and the strength of rubber by about ten-fold, but the amount of cross-linking must be controlled to avoid creating a brittle and inelastic substance.
Besides emitting large doses of hazardous chlorofluorocarbons (CFCs) into the air during the production process, rubber producers were also charged with creating end-user products that would not degrade.
Elasticity?
Temperture changes will affect the elasticity of rubber.
Rubber.
The elasticity of the rubber and sponge refers to the tendency of the rubber or the sponge to return to their original shape after they have been compressed or stretched.

Hooke's law is related to the elasticity of al; substances and, since rubber is a substance, Hooke's law is related to it!
Elasticity is about things that stretch and snap back, like rubber bands.
When left out in the sun rubber will loose some of its elasticity or crack, the ink will lose some color, and paper will be bleached or become whiter. This occurs because of the action of the ultraviolet light of the sun.
When a rubber ball is bounced, its molecular structure causes it to compress, but it cannot equalize the pressure by expanding on the other side, so the pent-up energy is rapidly used by decompressing the ball which causes the bounce.
