The parallel chains of stretched rubber are susceptible to crystallization. This takes some time because turns of twisted chains have to move out of the way of the growing crystallites. Crystallization has occurred, for example, when, after days, an inflated toy balloon is found withered at a relatively large remaining volume. Where it is touched, it shrinks because the temperature of the hand is enough to melt the crystals.

Wikipedia articles incorporating a citation from the 1911 Encyclopaedia Britannica with Wikisource reference Tree lace is the coagulum strip that the tapper peels off the previous cut before making a new cut. It usually has higher copper and manganese contents than cup lump. Both copper and manganese are pro-oxidants and can damage the physical properties of the dry rubber.Rubber mats are usually designed to be durable. Mats that are flimsy, delicate, or that have a finished surface may be damaged by power washers. Choose a gentle laundry detergent specifically designed for shoes or a mild washing up liquid. Avoid using harsh chemicals or bleach, as they can damage the rubber and fabric of your white trainers. Silicone offers many advantages over other forms of elastomers. It is well known for its use in food, pharmaceutical and other clean industry applications. It is a resilient material capable of maintaining many of its properties at extremely low and high temperatures. Some grades of silicone rubber can remain flexible, and show low levels of compression set, down to temperatures as low as -100 °C and as high as 315 °C. It is naturally electrically insulating but can be compounded to offer high resistance for the bleeding of static charges or to offer a low resistance to conduct signal voltages. High tear resistance, good elongation at break and tensile strength are some of the other characteristics of silicone. a b Heinz-Hermann Greve "Rubber, 2.
