  • Record expungementHDPE vs UHMW - Is One Better Than The Other? Before we look at the differences between these two plastics and compare which one is more applicable to specific industries or purposes, it helps to have at least a basic understanding of the qualities of both HDPE and UHMW. Here's a rundown of each one. HDPE stands for high density polyethylene.,In contrast to the relatively short chains of HDPE, the long chains of UHMWPE hamper the formation of crystalline layers, thus limiting the amount of crystalline material. The crystalline phase is formed by lamellae with thicknesses ranging from 10 to 50 nm and 1 to 50 μm in length with tie molecules connecting these lamellae, 5 where the amorphous phase is embedded ( Fig. 8.2 ). ,HDPE: A stiff plastic used for more robust plastic packaging like laundry detergent containers as well as for construction applications or trash bins. UHMW: Extremely strong plastic that can rival or even exceed steel in strength and is used is for applications like medical devices (e.g. artificial hips).
