UHMWPE Fiber

Commonly known as Spectra® or Dyneema®, these fibers offer an incredible strength-to-weight ratio, abrasion resistance, and flexibility.  It's the perfect choice for outdoor and industrial applications.  

You will get efficient and thoughtful service from longkui.

Our UHMWPE fiber is supplied in a continuous multi-filament configuration and is offered in various sizes, colors, and lengths. The fiber is precision wound and provided on a 5/8" x 5 1/4" cardboard tube, making for convenient handling and continued processing.  Additionally, each order includes product certification, guaranteeing the authenticity of your fiber purchase.

UHMWPE is a semi-crystalline, whitish and efficiently opaque engineering thermoplastic which, chemically, is an extremely high molecular weight (3-6 million) HDPE. As a result,it has a very high melt viscosity and can usually be processed only by powder sintering methods. It also has excellent cut and wear resistance and toughness and extremely good chemical resistance, to some extent better than that of HDPE.

Polymer Type

Advantages

Outstanding toughness cut and wear resistance. Excellent chemical resistance.  Good low temperature impact resistance.

Disadvantages

Not melt processable.

Applications

Can and bottle handling machine parts, moving parts on weaving machines, bearings, gears, artificial joints, chutes and slides for directing particulate solids.  Edge protection on ice rinks.  Butchers' chopping boards.

Applications also include a number of "wear parts" (example, bottle handling machine components), and marine quay headings. Fibers of extremely high molecular orientation can also be produced from polyethylene of very high molecular weight by gel spinning and subsequent drawing to provide fibers which are reported to be up to 85% crystalline and with 95% parallel orientation.

They are called Ultra High Modulus or High Performance Polyethylene fibers (UHMPE or HPPE). Goodfellow offers a modest range of fiber, braided cord, and fabrics.
