UHMW vs HDPE

Both UHMW and HDPE, are types of polyethylene plastic that can be used in various industrial applications. It’s important to understand the similarities and differences before purchasing to distinguish which material is more suitable for your needs.

At a molecular level, HDPE has a high-density makeup, meaning it doesn’t absorb much liquids. It can also be easily shaped and welded using thermoplastic equipment. It’s a low-cost, durable, abrasion, and chemical-resistant plastic material. HDPE is often used as a vessel or container, or for marine applications. 

On the other hand, UHMW is also low-cost and primarily used for applications that require extreme strength and abrasion resistance. This is an extremely popular plastic for wear industrial applications that require constant friction between moving parts over time. It’s also easy to fabricate and machine, but it's more difficult to form specific shapes or to weld.

There isn’t one choice that’s better suited to every application, but more about choosing which option is a better fit for your specific scenario. If you are unsure what plastic sheet to use for your application, please contact us.

UHMW vs Acetal

The primary difference is machining the two materials. UHMW is soft and more difficult to machine compared to Acetal due to its slippery form and it also suffers from thermal expansion. Acetal is a harder material with high mechanical strength and rigidity. It machines close to tolerance and performs better in precise (typically small) parts. They are both good alternatives to metal, with UHMW being the more economical option.

UHMW Fabrication Methods:

UHMW is highly versatile and easy to machine - even by a do-it-yourselfer. It’s cost-effective, outperforms metals in many applications, moisture-resistant, and easy to fabricate.

Cutting UHMW

UHMW can be sawed, turned, planed, milled, drilled, stamped, and welded easily on woodworking or metalworking machines. The following instructions are general guidelines to observe when machining UHMW.

Sawing UHMW

There are many ways to cut UHMW material - circular, bank, reciprocating, and guillotine saws are generally suitable. Band saws are particularly suitable for large cross-sections since they conduct the heat away and allow high cutting speeds. To prevent the saw blades from becoming jammed, the teeth must be set at approximately 0.5mm. When using circular saws, saw blades with a minimum setting of 0.5mm are also preferred.

UHMW does not harm the saw or blade, but if you are cutting a lot of it, there are few things you should watch out for. For example, if the blade speed slows while cutting the material, UHMW will produce “stringers” that can wrap around the arbor. It’s important to clean the end of the arbor at regular intervals. If you are cutting a thick piece of UHMW, it’s best to do short cuts as it will minimize the stringers and prolong the life of the saw.

Drilling UHMW

Plastics can build up heat very easily during drilling operations, especially when hole depths are greater than twice the diameter. Therefore, a cooling liquid is recommended. Lower RPM drilling is recommended. Twist drills are most commonly used for small diameter holes (0.5 - 25mm diameter) and thinned web (dubbed drill) is recommended for large diameter holes (25mm diameter and larger). This is because it reduces friction and heat generation. 

Welding UHMW

Because of its high melt viscosity, friction and butt welding are the only practical methods for joining by welding.

Polishing UHMW

ShapesPlastics experts recommend using a hand diamond lapper to polish grind marks.

ShapesPlastics Custom Fabrication

For users who do not have the skill, experience, tools, or time to fabricate these sheets, ShapesPlastics offers cut-to-size ad hoc services. The ability to create cut-to-size products that deliver the best quality, precision in cutting, and tight tolerances, is what truly sets us apart. You can also benefit from additional savings in shipping as cutting the sheet down to your final size, might qualify it for free standard shipping.

Cleaning / Maintaining UHMW

A popular method is wrapping UHMW parts with a self-sticking film. You can even wash them with standard dish soap and a little bleach to return to its natural color.

ShapesPlastics can meet your UHMW needs. We offer a variety of UHMW sheets in different thicknesses, sizes, colors, and grades. We carry a large inventory of popular brands in a variety of thicknesses. The thickness you need for your application depends entirely on the application at hand. If you are unsure about which thickness is suitable for your project, please contact us. We are backed by the industry's most knowledgeable sales team, have extensive experience, and can, with sufficient information, make a good estimate of the thickness to be used. If you need a larger sheet, request a free quote via the contact page.

We offer cut-to-size and fabrication options so you can get exactly what you need without the hassle of having to cut it yourself. We also provide value-added precision fabrication services such as drilling holes, diamond and flame polishing, rounded edges, radius corners, and state-of-the-art CNC routing and cutting services for exceptionally smooth surface finish.

Not only can we cut what you need, but we can also ship it for free if it is a standard size piece. We offer competitive prices, an easy-to-use website, and have knowledgeable staff that is ready to help point you in the right direction. Thinking of purchasing UHMW sheets at Home Depot or UHMW at Lowes? They don't cut to your specification and frankly, here at ShapesPlastics, we are less expensive and offer an array of services so you get exactly what you want.
