Consumer properties, which should be taken into consideration: 1) The unique toughness of the material (the highest rate of all known polymers), namely, Over 160 kJ/m2 2) High abrasion resistance 3) Low friction coefficient (self-lubricating) 4) High resistance to chemically aggressive reagents (media) 5) High creep resistance (geometric stability) Ordinary way - This type of process is quite expensive. Production of PE125, in compounding with bimodal PE100, from 8 to 45% of supermolecular polyethylene is injected, reaching dispersion by multiple compounding (4 stages) in an extruder cascade (XXXXX technology). GRAFTALEN™ MP-UHHD (alloy) is a MELT-PROCESSABLE concentrate of UHMWPE on an HDPE matrix. As HDPE, you can choose the most affordable HDPE (pipe) grade. To obtain polyethylene according to the standards PE125 (with a minimum strength indicator MRS> 13.8-14 MPa, in comparison PE100 has MRS only 10 MPa), a significant improvement in the resistance against hydrostatic pressure is required. For a conventional bimodal HDPE, this indicator is difficult to achieve, since it directly correlates with the impact strength/density indicators and with simple extrapolation, it turns out that the required indicator for PE125 simply does not reach the bimodal HDPE matrix. Another problem - the difficulty in maintaining the geometric stability of the pipe (the thickness at the top of the pipe is often less than at the bottom) due to the sagging effect (the phenomenon of the gravitational flow of a polymer melt). This phenomenon is more pronounced for thick-walled pipes. The specific blend of HDPE with UHMWPE allows solving these problems above.

It converts a vehicle engine into an air pump during decelerations. It harvests the braking energy and stores it as compressed air for subsequent use to restart the engine in stop/start operation, saving battery and starter motor life. It also saves fuel as the compressed air also assists the normal engine-driven air compressor. Furthermore it can enhance the turbo thus reducing black smoke during acceleration from stationary
