If the rubber is excessively heated, it could melt the rubberband and at the least will cause the rubberband to relax and stretch. If it is cilled, the rubber will become more rigid and lose elasticity. The real problem in any environent is that when the rubber becomes dehydradated, it startes to separate and when stretched tears and cracks causing the rubberband to break.

definite it does, yet in a touch unpredicted way. compared to maximum components, which improve at the same time as heated and settlement at the same time as cooled; rubber expands (relaxes) at the same time as cooled and contracts (loses elasticity) at the same time as heated. it truly is the inspiration of a nicely-beloved technology lab attempt: a wheel is created making use of rubber bands somewhat than the metal spokes. A warmth lamp is shone on the rubber bands on one fringe of the hub. because the settlement, the wheel turns into unbalanced and starts to educate. The rubber bands that go away the most objective of the nice and comfortable temperature lamp cool and go back to ther unique length, and the subsequent set are heated. This cycle repeats, and the wheel turns less than the skill of the nice and comfortable temperature lamp.

Rubber bands are made of a material called an elastomer, which is a type of polymer. Polymers have a unique property called a glass transition temperature. Below the glass transition temperature, the rubber is glass like, stiff. Above the glass transition temperature (Tg), the rubber is plyable and well, rubbery.
Natural rubber Tg is about (-71) deg C.

If it freezes, it will dry out and crack.
