3.1 MECHANICAL PROPERTIES
These are one piece tanks, rotationally molded of linear medium or high density
polyethylene or high density crosslinkable polyethylene (XLPE). Refer to material
type in the tank charts for availability. Tanks come in a variety of shapes, are avail-
able in closed head designs with flat bottom (IC, IA & IX series), conical bottom (JA
& JC series), round horizontal (LC & LA series) or oval horizontal (MC & MA
series).These tanks can be furnished with various accessories as per customer speci-
fications and are capable of holding aggressive chemicals at atmospheric pres-
sure. Open top mixing and processing tanks are available in cylindrical, conical
bottom and rectangular designs, refer to Chem-Tainer product catalog.
A high quality, chemically resistant plastic with high stress crack and impact resist-
ance. Linear polyethylene is translucent and exhibits properties that are ideal for
applications that are exposed to low temperatures and/or high impact. Unlike ther-
mosets, linear polyethylene is weldable, thus allowing for greater flexibility when
designing modification to our standard tanks. The plastic complies with USDA and
FDA regulations for storage and processing of food. Linear polyethylene is fully
recyclable and thereby provides a convenient method of disposal.
High density cross-linked polyethylene has excellent low temperature impact and
environmental stress-crack resistance. This polyethylene is a thermoset, thus does
not permit the utilization of welded tank connections. Cross-linked polyethylene
does not have USDA or FDA compliance for storage of processing edibles and is
not recyclable.
The plastic does contain a minimum of 0.25 to a maximum of 0.50 long term U.V.
stabilizer. It does not contain any fillers.
Pigment can be added at purchaser's request. These pigments would be compati-
ble with the polyethylene and will not exceed 0.5% dry blended and 2% com-
pounded in of the total weight.
