UHMW (Ultra High Molecular Weight Polyethylene) is a common machinable plastic known for durability, versatility and cost-effectiveness as well as abrasion, impact and chemical resistances. UHMW plastic features a molecular weight that ranges from 3.1 million to 100 million grams per mole, with an abrasion resistance that continues to improve as molecular weight increases.
Tivar® 88 is a specialized grade of UHMW recognized as the worldwide leader of premium lining material for bulk material handling, Due to its especially low coefficient of friction, Tivar® 88 is known for its performance in ensuring flow of bulk solids. Tivar® 88 liners are the ideal solution when you need to reduce or eliminate arching, ratholing, and erratic material flow challenges in bins, bunkers, hoppers, chutes, railcars and more.
Low Coefficient of Friction
Tivar® 88 is used in applications where high levels of friction are likely to arise including conveyor guard rails, augers and wear strips, belt scrapers, chain guides, and idler rollers. Due to an extremely low coefficient of friction, its inherent lubricity minimizes heat-generating friction that tends to gradually destroy steel parts, and ensures smooth, noiseless operation.
High durability, low friction and wear resistance are key reasons why Tivar® 88 is the material of choice for a myriad of applications. Tivar® 88 offers an extremely low coefficient of friction due to a specialized built-in lubricant that replaces unwanted grease and oil. It also enhances efficiency and productivity in many applications. Tivar® 88 self-lubricating formula helps to extend part life because the internal lubricant ensures that parts will not break or need replacement.
