TIVAR® Sterra™ DrySlide UHMW-PE

In response to the explosive growth in e-commerce and online shopping, manufacturing, and supply chain professionals are on the hunt for solutions to common industry problems such as package jams and damage, conveyor overload and shutdowns, slow package throughput, and hazardous safety conditions. The Advanced Materials Division of Mitsubishi Chemical Group (MCG) is solving these complex application challenges with our plastic material technologies, including our TIVAR® DrySlide UHMW-PE material.

• Clearing jams cause conveyor shutdowns & wasted man hours
• Problematic areas reduce flow & damaged packages
• Sprays & waxes are often used to increase package movement

• MCG Advanced Materials offers lining solutions to make the handling of parcels safer, faster, easier, and more efficient. The non-stick, non-wearing surface of TIVAR® DrySlide UHMW-PE promotes flow, ensures a reliable and safe operation, and prevents costly downtime, maintenance, and repair.
• When you need to move packages, TIVAR® DrySlide UHMW-PE does the job. Modified with special lubricants, it has the lowest coefficient of friction of any of the TIVAR® lining products. The enhanced coefficient of friction and antistatic properties make TIVAR® DrySlide UHMW-PE an excellent performer in dry, dusty, or dirty environments.
• In addition, the enhanced surface lubricity eliminates sprays and waxes, allowing packaging or products to move freely without jamming from dirt, grit, or static build-up.
• TIVAR® DrySlide UHMW-PE solves complicated wear & material flow issues while reducing downtime.

TIVAR® DrySlide UHMW-PE tackles the toughest package handling challenges

• Damp packages & moisture - Ideal for humid environments
• Shrink wrap & tape - Non-stick and self-lubricating
• Lightweight packages  - optimized sliding on sloped angles
• Static build-up - Anti-static/ESd
• Magnetic materials & parcels - Antimagnetic
   

1. Dry running: Provides smooth continuous motion with no chute lube.
2. Anti-static/ESd: Controls static electricity formation & conduction.
3. Reduces sound: Lessens noise pollution.
4. Material flow: Solves material handling flow issues.
5. High abrasion: Long-term abrasion & corrosion resistance.
6. Impact resistance: Protects against severe impact.

• This table, mainly to be used for comparison purposes, is a valuable help in the choice of material. The data listed here fall within the normal range of product properties of dry material. However, they are not guaranteed and should not be used to establish material specification limits or alone as the basis of design. See the remaining notes on the next page.
• ¹ The figures given for these properties are for the most part derived from raw material supplier data and other publications.
• ² Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature (PBI & PI).
• ³ Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength – measured at 23 °C – of about 50 % as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes place and causes a reduction in properties. Note, however, that the maximum allowable service temperature depends in many cases essentially on the duration and the magnitude of the mechanical stresses to which the material is subjected.
• ⁴ Impact strength decreases with decreasing temperature, the minimum allowable service temperature is practically mainly determined by the extent to which the material is subjected to impact. The value given here is based on unfavorable impact conditions and may consequently not be considered as being the absolute practical limit.
• ⁵ These estimated ratings, derived from raw material supplier data and other publications, are not intended to reflect hazards presented by the material under actual fire conditions. There is no ‘UL File Number’ available for these stock shapes.
• ⁶ Most of the figures given for the mechanical properties are average values of tests run on dry test specimens machined out of rods 40-60 mm when available, else out of plate 10-20mm. All tests are done at room temperature (23° / 73°F)

• ⁸ Test speed: either 0.2"/min or 2"/min or [chosen as a function of the ductile behavior of the material (brittle or tough)] using Type 1 tensile bars
• ⁹ Test speed: 1 mm/min, using type 1B tensile bars
