Corrosion-resistant UHMWPE plastic outrigger pads
UHMWPE’s ultra-high molecular weight gives it excellent performance, and it is a moderate-priced, high-performance thermoplastic engineering plastic. It almost combines the advantages of various plastics. Corrosion resistance, impact energy absorption, low temperature resistance, sanitation and environmental protection, not easy to adhere, not easy to absorb water, low density and other comprehensive properties. In fact, no polymer material has so many excellent properties.
Abrasion resistance of plastic outrigger pads
The wear resistance of UHMWPE ranks first among plastics and surpasses some metals. Compared with other engineering plastics, UHMWPE’s mortar wear index is only 1/5 of PA66 and 1/10 of HDPE and PVC. Compared with metal, it is 1/7 of carbon steel and 1/27 of brass. Such a high abrasion resistance makes it difficult for ordinary plastic abrasion experiments to test its abrasion resistance. Therefore, a mortar abrasion test device is specially designed. UHMWPE wear resistance is directly proportional to molecular weight. The higher the molecular weight, the better the wear resistance.
Impact resistance of plastic outrigger pads
The impact strength of UHMWPE is among the best in all engineering plastics. The impact strength of UHMWPE is about 2 times that of impact-resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP. The impact resistance is so high that it is difficult to break it by the usual impact test method. Its impact strength increases with increasing molecular weight, reaches a peak when the molecular weight is 1.5 million, and then gradually decreases as the molecular weight continues to increase. It is worth pointing out that it can also maintain excellent impact strength in liquid nitrogen (-195 ° C), which is a characteristic that other plastics do not have. In addition, it has higher surface hardness in repeated impacts.
