Mach4 UHMPE Bulk Material Lining Grade

Mach4 UHMWPE sheet

Mach4 UHMPE is recognized as a premium lining material for bulk material handling. Its amazing performance in promoting bulk solids flow of cohesive or non-free flowing materials is a life-saver for high production manufacturers. Controlling and promoting flow of bulk material is the key reason production facilities choose Mach4 lining grade sheets.

Mach4 Key Features:

  • Promotes Bulk Material Flow

Frequently Asked Questions

UHMPE is the abbreviation for Ultra High Mechanical Polyethylene. It is a superior resin engineered to operate in demanding applications combining low co-efficient of friction, excellent abrasion resistance and high impact resistance. UHMPE is generally compression molded in high pressure molds, however some manufacturers experience success with specialty extrusion systems designed to withstand the extreme pressures required. Key physical properties include “no break” notched izod, extremely low co-efficient of friction, FDA compliance for direct food contact, and good abrasion resistance.

 Low co-efficient of friction, High impact strength, and excellent abrasion resistance are key properties of Mach UHMPE sheet. Another factor that doesn’t go unnoticed by fabricators is the ease of machining.

Mach sheet is very chemical resistant however it is important to verify which chemicals are OK. Please refer to the chemical charts listed on our web listed under resources.

Sun – no problem!  Rain or sea water – no effect!  Wind – no problem!

Mach UHMPE is a closed cell structure resin which will not accept coatings.

In theory UHMPE cannot be welded, however our Mach sheet is engineered with specific additives to make this possible. Only trained polymer extrusion welders should attempt this.

Standard woodworking tools work well. We recommend using very sharp tooling. For best results use carbide cutters.

Standard woodworking and steel working drill bits work well. For larger diameter holes, use spade bits or holes saws.

Due to its low coefficient of friction, Mach UHMPE sheet creates almost zero resistance, therefore based on the law of motion the velocity of anything sliding over it is increased compared to most other plastic sheets.

A key component of the Mach sheet is its ability to withstand high impact forces. This is due to the engineering of the UHMPE resin, which has a tightly knit molecular structure. These “chains” in the sheet absorb the impact while locking the polymer and keep it from cracking.

No. The slippery surface will always remain, even if the sheet is worn to half its thickness. The slippery surface is not just a surface treatment that you see with many other plastics, it is inherent to its structure and is throughout the material. Our trademarked AAF™ (Accelerated Anti-Friction) is through the entire thickness of the panel, therefore you will always receive the benefit of amazing slip!

Mach sheet is used by all industries but is a staple in the Industrial, Agriculture and Food, and Original Equipment Manufacturers(OEM) of all industries.

UHMPE has no UL recognition. An estimate is that it would be a HB (Horizontal Burn) on UL-1; that is slow burning (less than 3” per minute).

Mach sheet can operate continuously up to 180°F. The Extreme OPS Mach 6 can operate up to 200°F intermittently.

Mach sheet can be installed with mechanical fasteners. Care must be taken to allow for thermal expansion, which is standard for most plastic sheet materials.
