Question 1

What is TIVAR88?

Accepted Answer

TIVAR88 is a premium glass-filled grade of UHMW-PE that offers low moisture absorption, a low coefficient of friction, and excellent chemical resistance. TIVAR88 components are designed to combat flow stoppage, prevent dead volume and allow bulk materials to flow freely. For these reasons, TIVAR88 is considered the material of choice for the lining of storage and transportation containers, hoppers, chutes, bunkers, and other bulk material handling equipment.

Question 2

Where to buy TIVAR88?

Accepted Answer

Plastruct Polyzone distributes, machines, and fabricates TIVAR88 and a wide range of industrial polymers.

Question 3

What are the benefits of TIVAR 88?

Accepted Answer

TIVAR 88 has excellent resistance to wear, abrasion, chemicals, and corrosion. Along with its low coefficient of friction and zero moisture absorption, these benefits allow TIVAR88 to promote reliable and steady bulk material flow and can help reduce or eliminate arching, rat-holing, and erratic flow in a wide range of bulk material handling environments.

Question 4

What is the difference between TIVAR88 and TIVAR88-2?

Accepted Answer

TIVAR88-2 retains all the characteristics of TIVAR88, however, comes with the added benefits of an even lower coefficient of friction and the ability to be plastic-welded and fabricated. The ability to weld allows for seamless liners and reduces the possibility of material hang-up points.

Question 5

What is the coefficient of friction of TIVAR88?

Accepted Answer

TIVAR88 has a coefficient of friction of 0.12 (QTM 55007 (20))

Question 6

How hard is TIVAR88?

Accepted Answer

TIVAR88 has a Shore D hardness value of 69 (ASTM D2240)

Question 7

What is the melting point of TIVAR88?

Accepted Answer

The melting point of TIVAR88 is 275°F. (ASTM D3418)

Question 8

What is the compressive strength of TIVAR88?

Accepted Answer

TIVAR88 has a compressive strength of 3000PSI. (ASTM D695 (11))

Question 9

What is the tensile strength of TIVAR88?

Accepted Answer

TIVAR88 has a tensile strength of 5800 PSI. (ASTM D638 (8))

Question 10

Is TIVAR88 approved for food contact?

Accepted Answer

No, TIVAR88 is not approved for use in food handling applications, however, TIVAR1000 virgin UHMW-PE is FDA compliant and an excellent performer in food handling and production facilities.
