When bare metal or standard UHMW-PE can't stop bridging, ratholing, and hang-ups in hoppers, chutes, and bins, TIVAR® 88 is the grade engineered specifically for gravity-fed and pneumatic bulk flow. Emco stocks and fabricates it to print.
TIVAR® 88 is Mitsubishi Chemical's premium glass-filled UHMW-PE, engineered around one core problem: material that won't flow. Its low coefficient of friction and low moisture pickup let bulk solids — from aggregate and coal to grain and chemical powders — slide freely instead of bridging, arching, or packing against liner walls.
| Grade | Formulation | Best fit when… |
|---|---|---|
| TIVAR® 88 | Premium glass-filled UHMW-PE | You need the baseline low-friction, low-moisture liner for general bulk storage and transport — hoppers, bins, chutes, stand pipes. |
| TIVAR® 88-2 | Premium lubricant-filled, UV stabilized | The application needs the lowest coefficient of friction in the 88 family, or the liner will see sustained outdoor UV exposure. |
| TIVAR® 88 ESD | Glass-filled, cross-linked, static-dissipative | Dusty or volatile bulk material creates a static discharge risk and the line needs charge dissipation without giving up flow performance. |
Tell Emco what's bridging, hanging up, or wearing out — we'll cross-reference the TIVAR® 88 family and quote stock, sheet, or a fabricated liner kit ready to install.
