COPPER
CUSTOM-ENGINEERED
SOLUTIONS IN
KNITTED WIRE MESH

For forty years, Metex
design, development, and
manufacturing engineers have
been producing engineered
components that take maximum advantage of the
unique characteristics and
robust nature of knitted wire
mesh. Its interlocked looped
structure, which offers excellent resiliency, memory—
even when subjected to
high temperatures as well
as high-tensile or compressive stress—and strength,
make knitted wire the ideal
choice in materials when
both performance and cost
are paramount.
Metex products now
meet a wide range of critical
needs—from providing flexible, yet durable, seals and
joints to noise attenuation,
thermal insulation, and filtration—in some of the most
demanding industrial applications and environments.

GAUZE

Clean Critical Plastic Extrusion Equipment—And
Reduce Downtime—with Metex Copper Gauze
Metex copper gauze is a proven, economical way to clean plastic extrusion
equipment and molds—in a fraction of the time required by household
cleaning products—while the machinery is still hot. Metex copper gauze helps
dramatically reduce downtime—with as much as 120 hours of additional
machine output achieved with a typical low-compression, single-screw, 2 1/2"
extruder.
This versatile cleaning material has been used by many leading plastic converters to clean extruders, dies, screws, and similar machinery. It is especially
economical where product purity requires frequent maintenance—for example,
when molding material or color must be changed often, or thin films coated.
Among the many proven applications for Metex copper gauze are removal
of “drool” on sheeting extruders or tubing dies, cleaning vent holes in dies and
injection molds as well as extrusion screws and barrels. Copper gauze is:
s Safe
Soft copper will never scratch or damage costly machine parts. No metal splinters make it
safe for workmen, too.
s

Rust-Free
Pure, solid copper will not rust or contaminate end product.

s

Tough
Interlocked loops of heavy gauge copper wire make it impervious to disintegration.

s

Effective
Knitted structure keeps flat wire on edge for excellent scraping action without scratching.

s

Non-Flammable
Because Metex knitted copper gauze is 100% metal, it can’t burn or even smoke when used
directly on hot equipment.

s

Low Cost
Costs less than currently used household-type metallic cleaners.

s

Efficient
Compared to other methods (charring, wire brushes, metal sponges), Metex knitted copper
gauze cleans in less time—often less than one hour to clean a machine.

s

Two Grades in One
You get two grades of cleaning power in one grade of Metex knitted copper gauze. Use as
supplied for normal cleaning, or turn insideout for heavy cleaning.
