1·Despite the invention of synthetic rubbers, there is often no good substitute for the real thing, for nothing artificial yet matches natural rubber's resilience and strength.
尽管人类发明了合成橡胶，但现在没有能替代天然橡胶的好产品，因为人工合成橡胶弹力和强度还无法和天然橡胶相比。
2·But now tough, new rubbers have come to the rescue. Moreover, these rubbers are not being used just as pads.
但是现在新的更耐磨的橡胶出现了，解决了这个问题。
3·Nonmetallic materials are those materials such as woods, plastics, rubbers, epoxy resins, ceramics and diamonds that do not have a metallic base.
非金属材料是指如木头，塑料，橡胶，环氧树脂，陶瓷及金刚石等那些不含有金属基材的材料。
4·Hot rubbers are branched and contain some crosslinked gel.
热橡胶是支链的，并含有一些交联凝胶。
5·Produced by emulsion polymerization in a similar way to styrene-butadiene rubber processes, yielding both "hot" and "cold" rubbers.
生产方法是乳液聚合，和苯乙烯-丁二烯橡胶的生产过程相似，得到“热”橡胶和“冷”橡胶。
