As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Tivar® 88 UHMW (Ultra High Molecular Weight Polyethylene) is a specialized grade made specifically for bulk material handling. Dark blue in color, it is a versatile, cost-effective machinable plastic with extreme durability and exceptional resistance to abrasion, impact, and chemicals.
Featuring an very low coefficient of friction, Tivar® 88 helps promote the smooth flow of cohesive or non-free flowing bulk solids. It is the ideal, proven solution when you need to reduce or eliminate arching, ratholing, and erratic material flow challenges in bins, bunkers, hoppers, chutes, and railcars.
Tivar® 88 is a premium glass-filled grade engineered to optimize bulk material flow and extend part life without the need for external surface coatings. It is the correct choice if you need:
Reliable Material Flow:
Promotes steady bulk material flow and solves erratic flow issues like arching (stagnant material clinging to the walls) and ratholing (arching over the hopper outlet).
Premium Glass-Filled Grade:
The specialized glass-filled polymer matrix provides a remarkably low coefficient of friction and exceptional wear resistance that reduces liner wear and maintenance.
Extreme Durability:
High wear resistance ensures that parts will not easily break or require frequent replacement.
Low Moisture Absorption:
Absorbs almost no moisture, helping reduce sticking and freezing-related hang-up.
Noise Reduction:
Can help reduce noise and friction in sliding contact applications.
Tivar® 88 vs. Virgin UHMW: Which Do You Need?
While both offer excellent impact strength, they are engineered for different purposes.
Choose Tivar® 88 (This Sheet) if you are handling bulk solids and need to reduce bridging, ratholing, and erratic flow. Its glass-filled formulation provides lower surface friction and improved wear performance for demanding bulk material handling environments.
Choose Virgin UHMW if you need general sliding abrasion resistance at a lower price point, but do not require the highly specialized glass-filled formulation found in Tivar® 88.
Fabrication & Machining
Because Tivar® 88 is a premium glass-filled grade, it is highly abrasive to standard tooling. While it can be machined, cut, and drilled, carbide-tipped tools are strongly recommended to prevent rapid blade dulling. Note that its high toughness means it does not hold fine threads as well as stiffer plastics like Nylon or Acetal (Delrin®). Use coarse threads or metal inserts for best results.
Handling: Cut sheets may have sharp edges. We recommend wearing protective gloves when unpacking and handling this material to ensure safety.
Suitability: We take pride in the quality of our materials as they leave our facility. However, because every project is unique, we cannot account for how materials are modified, stored, or used after delivery. Please perform the necessary tests to ensure this material is right for your specific application and end-use conditions.
UHM8V SH
Technical Performance
Engineered specifically for severe wear environments, Tivar® 88 features a premium glass-filled formulation that significantly improves sliding abrasion resistance compared to standard UHMW. This unique polymer matrix promotes the steady flow of cohesive or non-free flowing bulk solids, combating flow stoppage without relying on temporary surface coatings.
Specialized formulation is engineered to improve flow without relying on temporary surface coatings and provides a low coefficient of friction to keep bulk materials flowing freely.
Abrasion Resistance:
Features an ultra-high molecular weight that provides exceptional resistance to sliding abrasion and heavy impact.
Moisture Absorption:
Exhibits very low moisture absorption, helping maintain steady bulk material flow and reduce sticking-related hang-up.
Key Properties
Flow Promotion:
Helps improve discharge rates and reduce costly production downtime caused by bridging, arching, and ratholing.
Extreme Durability:
High wear resistance helps extend service life and reduce replacement frequency in demanding bulk-handling environments.
Chemical Resistance:
Offers strong resistance to abrasion, chemicals, and corrosive environments common in industrial bulk-handling applications.
Noise Dampening:
The material's exceptionally low coefficient of friction can help reduce noise and friction in some sliding contact applications.
Common Industrial Applications
Bulk Material Handling: Lining material for bins, bunkers, hoppers, chutes, and railcars.
Storage & Transport Equipment: Liners for containers, transfer points, and handling systems where steady material flow is critical.
Conveying Systems: Conveyor liners, vibratory pans, and related flow surfaces exposed to sliding abrasion.
Wear Liners: Lining surfaces in severe bulk solids environments where low friction and abrasion resistance are needed.
Engineering Limitations & Alternatives
While Tivar® 88 is the premier solution for bulk material flow and wear resistance, specific environments may require stiffer or more heat-resistant materials:
Structural Rigidity: Though Tivar® 88 is glass-filled and less affected than other grades, UHMW is softer than other engineering plastics and susceptible to "creep" (cold flow) under heavy static loads. Better Alternative: For high-load bearings or structural gears, choose Cast Nylon.
Machining Tolerances: Due to its high coefficient of thermal expansion, it is difficult to hold extremely tight tolerances. Better Alternative: For precision machined parts requiring stiffness, consider Acetal (Delrin®).
High Heat: Continuous service usage near or above 180°F can reduce its stiffness and performance. Better Alternative: For high-heat wear applications, consider PTFE (Teflon®).
