Superior electric power resistance is another useful good thing about polypropylene, rendering it suitable with production electrical parts.
近年來亦大量使用於製成免洗餐具（例如供餐飲業者裝填食品使用、手搖飲料店所用之盛裝容器）
耐热且化学稳定性比较高。本质上和高密度聚乙烯接近，结晶度比高密度聚乙烯略低，所以一般呈现半透明的状态，而硬度与高密度聚乙烯差不太多。
As an example, polyethylene floorcloth feels tender but, not like normal choices, is very stain-resistant and will never develop to fade or mildew when subjected to outdoor things. This can make them exceptional methods for outdoor and indoor parts with large dampness.
