UHMW Adhesive Backed Sheet and Tape

UMMW-PE could be characterized as one of the miracle polymers of the 20th century. The incredible durability and versatility of UHMW make it a favorite among engineers and designers in nearly every industry worldwide. The key is UHMW's incredibly long molecular chain, which give UHMW a host of exceptional attributes such as high abrasion resistance, low coefficient of friction and unparalleled impact resistance, even in cryogenic environments.

Due to UHMW s large molecular chain, the molecular weight can range from a low of 3.1 million and can go as high as 10 million. While impact strength is maximized at about 3.5 - 4 million, abrasion resistance will continue to improve as the molecular weight increases. This makes it an ideal product for use in applications where wear and friction play a part. Industries such as material handling, food processing, automotive, railroad, agriculture, medical, printing and packaging all have numerous applications where UHMW coatings and materials can provide benefits and enhance efficiency and productivity.

UHMW s high molecular weight prevents it from being produced by methods typical of lower grade polymers. UHMW does not possess a melt flow which limits its manufacturing process to compression molding. These processes include flat bed presses and ram extrusion, with thin films being produced by skiving ram extruded or compression molded billets.

Alro Plastics has partnered with Crown Plastics Company, who utilizes the world's only true process of continuous compression molding which heats, compresses and cools the UHMW directly to thickness in a continuous flow allowing for long continuous rolls with low stress and tight tolerance.

Crown Plastics has also mastered the art of surface treatment of UHMW thereby transforming UHMW into a material or coating that is highly bondable. UHMW can be supplied from Crown Plastics with a pressure sensitive adhesive system (peel and stick) or one side abraded for use with contact cements or epoxies. These options eliminate the need for mechanical fastening and open up unlimited application opportunities for UHMW. To discuss applications or ideas where bondable UHMW can be used please contact Alro Plastics.

Continuous Press UHMW Rolls

Pressure sensitive tapes and materials can be applied in areas where mechanical fastening is undesirable due to cost or application demands. The substrate should be as smooth as possible and must be clean and free of any potential contamination. A totally evaporating solvent such as acetone is recommended where permitted. Applications for UHMW pressure sensitive tapes and materials include guides, washers, gaskets, work surfaces, and countless friction and wear areas.


ADVANTAGES OF THIS METHOD:

  • Continuous compression molding allows for longer rolls for easier handling when machining parts, cutting pieces, and for little or no seams in glide rails and conveyer systems.
  • Pressure sensitive adhesive for applications where mechanical fastening is not practical or for less labor intensive installation.
  • A variety of thickness gauges (.003" to .125") with better tolerances.
  • Custom slitting

UHMW PRODUCT BENEFITS:

  • The highest abrasion resistance of any thermoplastic polymer
  • Outstanding impact strength even at very low temperatures
  • An excellent sliding material due to the low coefficient of friction
  • Self-lubricating (non-caking and sticking)
  • Sound dampening properties
  • Good chemical and stress cracking resistance
  • Easily machined
  • FDA and USDA approved

INDUSTRIES USING UHMW:

  • Material Handling
  • Food and Beverage
  • Agricultural
  • Woodworking and Lumbering
  • Environmental
  • Recreation
  • Transportation
  • Packaging and Printing
