Ultra-high molecular weight HDPE

There are also ultra high molecular weight grades of HDPE. 

Major markets for LDPE are in packaging and sheeting, whereas HDPE is used mainly in blow-molded products (milk bottles, household and cosmetic bottles, fuel tanks), and in pipe, wire, and cable applications. Ultra-high-molecular-weight polyethylene materials (see later), which are the toughest of plastics, are doing an unusual job in the textile machinery field. 

Additionally ultra high molecular weight polyethylene (UHMWPE) typically has a molecular weight 10 times that of HDPE. 

High-density polyethylene (HDPE)/ultra-high molecular weight polyethylene (UHMWPE) blends are possible by direct compounding, and use of UHMWPE could improve the impact strength or tensile strain of HDPE. The effect of the UHMWPE content on the mechanical properties of the HDPE/UHMWPE blends is improved by compounding due to homogenisation of the mixture [35-39].

Applications of scanning electron microscopy (SEM) to polymer characterisation and microstructure include studies on the zwitterions-type polymer, poly(3-diethyl methylmethacryloyl ethyl) ammonium persulfonate grafted on to a silica surface by treatment of poly(2-dimethyl amino) ethyl methacrylate [2], polyaniline coated glass fibre fillers with different polyaniline contents [3], and also studies on ultra high molecular weight blends [4] and high-density polyethylene (HDPE)-gamma ferric oxide composite films [5].
