ANULON-98 High Density Polyethylene (HDPE)

Back

ANULON-98 High Density Polyethylene (HDPE) is a highly crystalline nonpolar thermoplastic polyolefin. It is highly resistant to most household and industrial chemicals; thus ANULON-98 pipes, pipe fittings, valves and tanks are used for transportation and storage of such chemicals. It does not absorb moisture and provides good water vapor barrier, which makes it useful in lining applications.

Salient Features of ANULON-98

Exceptional wear and abrasion resistance

Excellent corrosion resistance

Low weight

Low coefficient of friction

Very good toughness and resilience

Outstanding resistance to repeated impacts

Low noise factor

Self Iubricating

Easy machinability

Economical compared to many alternatives
