4' X 10'
SHEETS
PRIME UHMW
POLYETHYLENE
TECHNICAL INFORMATION:
Material:
Virgin UHMW (ultra high molecular weight) polyethylene.
Molecular Weight:
3.1 to 6.0 million. (5.0 million average)
Method of Manufacture:
Compression molded.
Color:
White, other colors available on special order.
Temperature:
-60°F to +225°F/ -51°C to +107°C.
Flammability:
UHMW polyethylene is termed “slow burning”. Combus-
tion in an excess of air results in harmless by-products (fumes) which
are nontoxic.
Limitations:
As a lining material, UHMW sheeting should not be used for
the following: (1) Hard or sharp material, such as rocks or sharp glass.
(2) In glancing impact areas. (3) In high velocity chutes. (4) In chutes that
make rapid change of direction.
