hdpe bottle cap is both hdpe bottle cap according to the molecular weight can be divided into low, medium, high, super high and other several,

Low density hdpe cap (LDPE) molecular weight of less than 1 million, such as PE80, PE100, etc.;

The molecular weight of the medium-density hdpe bottle cap is between 1 million and 1.5 million, also known as MDPE;

The molecular weight of high-density hdpe bottle caps is about 2 million, also known as HDPE;

The molecular weight of the bottle cap (referred to as the ultra high molecular weight cap) is between 2.5 million and 3.5 million, also known as UHMW-PE, its wear resistance and corrosion resistance is more than 2-10 times that of the high, medium and low density hdpe bottle cap, and it is also the currently recognized engineering plastic with higher wear resistance.

The wear resistant anticorrosive bottle cap is generally used in the liner hdpe bottle cap anticorrosive technology, giving the bottle cap enough strength and toughness at the same time to give it important anticorrosive ability and wear resistance. Because the hdpe bottle cap material has low friction and high wear resistance, and is easy to form, a high-strength corrosion-resistant bottle cap can be obtained by direct pouring after the steel structure is fixed.

The impact resistance and impact absorption of ultra-high molecular weight hdpe bottle caps are the first in plastic, whether it is a strong external impact, or internal pressure fluctuations are difficult to make it crack. The impact strength of the bottle cap is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 4 times that of hdpe bottle cap. Especially in the low temperature environment, its impact strength reaches a higher value, and its superiority is also higher. This flexibility of the ultra-high molecular weight hdpe bottle cap provides a safe and reliable guarantee for the delivery system.

Among many bottle cap materials, the friction coefficient of ultra-high molecular weight hdpe bottle cap is the smallest, and the ultra-high molecular chain is particularly long, making the wear resistance of ultra-high molecular weight hdpe bottle cap material 4-7 times higher than that of the cylinder cap and stainless steel bottle cap when conveying various slurry, and about 10 times higher than that of the hdpe bottle cap crushing material and hdpe bottle cap. The service life of the bottle cap is greatly improved. The long service life is not only cost savings, but also a safe and reliable guarantee.

Therefore, when oil transportation, natural gas bottle caps and so on have strong corrosive and frictional fluids, it is necessary to use this hdpe bottle cap liner wear-resistant and anti-corrosion bottle cap.
