TIVAR® HPV UHMW-PE | Emco Industrial Plastics

BEARING-GRADE UHMW-PE · DRY LUBRICANT SYSTEM

TIVAR® HPV UHMW-PE
Built-in lubricant. Fewer touch points to babysit.

TIVAR® HPV is a bearing-grade UHMW-PE with a proprietary internal dry lubricant that cuts coefficient of friction by up to 80% versus standard UHMW-PE — without oils, greases, or re-lubrication schedules. It's built for chain guides, sliding strips, wear bends, and rollers running hot, fast, and unattended.

FDA 21 CFR §177.1520

COF: 0.09 (DYNAMIC)

SERVICE TO -200°C

HPV FG AVAILABLE

WHY IT GETS SPECIFIED

A dry lubricant that lives inside the material

Standard UHMW-PE already runs low-friction and self-lubricating. TIVAR® HPV goes further by compounding a dry lubricant directly into the resin, so the low-friction surface doesn't wear away or need reapplication — it regenerates as the part wears.

Up to 80% COF reduction versus general-purpose UHMW-PE, measured dynamic coefficient of friction as low as 0.09.
Higher limiting PV — parts tolerate more pressure at higher sliding speed before heat buildup causes wear or deformation.
No re-lubrication — the dry lubricant is compounded through the material, not a surface coating that wipes off.
FDA 21 CFR §177.1520 compliant in its natural formulation, with HPV FG available for washdown/food-contact environments.

Friction comparison across the TIVAR® family

Directional comparison of dynamic coefficient of friction against a steel counterface. Lower is better. Values reflect Mitsubishi Chemical Group published test data; actual results vary with load, speed, and surface finish.

FIG. 02

Where HPV earns its keep on the line

The built-in lubricant matters most where parts see constant sliding contact and are hard to reach for maintenance.

GRADE VARIANTS

Choosing between HPV and HPV FG

Both grades share the same built-in dry lubricant chemistry. The difference is regulatory fit for the environment the part lives in.

STANDARD

TIVAR® HPV UHMW-PE

The base bearing grade. FDA 21 CFR §177.1520 compliant in natural blue coloring, built for chain guides, sliding strips, corner wear bends, and roller/bushing applications in general industrial, packaging, and bulk-handling equipment.

FOOD GRADE

TIVAR® HPV FG UHMW-PE

Formulated for food and beverage processing lines running high speeds, high loads, elevated temperatures, and aggressive washdown chemistry — where the low-COF, high-limiting-PV performance of HPV needs to hold up under sanitation cycles.
