LUBMER™

LUBMER™ is a special polyethylene developed by Mitsui Chemicals using proprietary polymerization technology. It is in pellet form and can be injection molded or extrusion molded.
LUBMER™ has the characteristics of high sliding properties, abrasion resistance, chemical resistance, noise reduction which is a characteristic of ultra-high molecular weight polyethylene.
In addition to standalone molding, it can also be used as an additive to improve the sliding properties and abrasion resistance of engineering plastics.

Summary

UHMW-PE stands for Ultra-High Molecular Weight Polyethylene, and as the name suggests, refers to a type of polyethylene with a very high molecular weight. Ultra-high molecular weight polyethylene has an average molecular weight of at least 1,000,000, exhibits excellent sliding properties and abrasion resistance and is a polyethylene classified as and engineering plastic that possesses high strength. In response to recent trends in PFAS regulations, it is attracting attention as a substitute material for PTFE, and its track record and reputation are rapidly increasing.

Sliding properties

Lubmer^TM demonstrates a low coefficient of friction similar to fluoropolimers and exhibits superior abrasion resistance to other polyolefins and engineering plastics.

Abrasion resistance

Lubmer^TMexhibits superior overall abrasion resistance compared to polyacetal, nylon and PBT. It possesses good abrasion resistance that is a characteristic to ultra-high molecular weight polyethylene.

Chemical resistance

Lubmer^TMis stable against various chemicals particularly against acids, alkalis and alcohol.

Noiseless properties

Lubmer^TMdoes not easily generate a squeaking noise even when combined with various other materials. This makes it ideal for applications where quiet operation is required.

Using Lubmer™ as a modifier

LUBMER™ LY1040 can be used as an additive in engineering plastics. Figures below show the decrease in the coefficient of friction (COF) and abrasion loss by addition of 5wt% and 10wt% LY1040 to various materials.
