贝克兰建立了通用酚醛塑料公司，不仅制造酚醛塑料，而且颁发它的生产许可证。

Baekeland founded the Central Bakelite Corp. to both make and license the manufacture of Bakelite.

试验结果表明，模压前合理的预热可以显著地提高酚醛塑料的电性能及力学性能；

The effect of preheating, test-piece thickness and coupling agents on the electric properties and the mechanical properties of the materials have been specially studied.

特富龙、聚乙烯和蓝宝石是高质量绝缘材料的例子，但要避免使用酚醛塑料和尼龙等材料。

Teflon, polyethylene, and sapphire are examples of good quality insulators, but avoid materials like phenolics and nylon.
