TIVAR® 88 is used in numerous industries and prized for its excellent mechanical properties and resistance to various stresses. Easy to recognize thanks to its dark blue colour, this high-performance plastic is ideal for extreme environments, as it contains additives added directly to its resin. In this article, we will discuss the 5 main advantages of TIVAR® 88 as well as its most common applications.
1. High resistance to abrasion and impacts
TIVAR® 88 is a UHMW that contains a glass additive, which provides superior resistance to wear. For applications where friction is a major concern, TIVAR® 88 helps protect the surface to which it's attached and facilitates the flow of materials through chutes.

2. Lightweight and highly efficient
In addition to its excellent mechanical properties, TIVAR® 88 is also a very light material. In fact, it’s nearly 90% lighter than steel.
Plastics can provide an interesting solution when weight must be taken into account. To learn more about the weight of plastics, see our article: The weight of plastics: Combining performance and lightness.
Grade 88-2 is known for being easy to weld, which allows for larger custom projects. In the mining industry, TIVAR® 88 is a preferred material for high-performance liners because of this feature. This characteristic also reduces the risk of material infiltration, for example between the liner and walls of a chute, thus increasing the efficiency and the service life of the equipment.
4. Low coefficient of friction
TIVAR® 88 possesses an extremely low dynamic coefficient of friction (0.08), making its surface so smooth that nothing sticks to it. This advantage facilitates the transportation of bulk material by promoting uniform flow in chutes and conveyors while reducing the risk of clogging at critical points.
5. Excellent thermal resistance
TIVAR® 88 can be used in a broad range of temperatures, from -200 °C to 80 °C. It's therefore a material of choice for environments that reach continuous temperatures of up to 80 °C. It's also frequently used in the manufacturing of scraper knives, as it performs well even at low temperatures.
