The twine is
knitted into sheets on a net-making machine. A pressure of 5 tons
is then applied to the net to stretch it into squares. The net is
then heat set in an enclosed system at a temperature of 200 F for
3 minutes.
Standard mesh
sizes are 3/4", 1-1/8" and 2", but other mesh sizes can be manufactured.
Nets can be custom made in any length or width. For ease of installation,
corners and long sides are marked. StealthNet is available in stock
colors of Black, Stone (beige) and Translucent, with White available
by special order.
Thermal Properties
Softening point in the region of 250º F.
Effect of
High Temperature
Melting point in excess of 270º F. Burns with difficulty. May be
heated for short periods up to 600º F.
Effect of
Low Temperatures
Polyethylene retains its flexibility at very low temperatures and
does not become rigid under freezing conditions.
Flammability
Burns slowly in air (ASTM Test 1.0î/min); fine filaments tend to
melt and drop away before propagating a flame.
Chemical
Properties
Polyethylene, a paraffin hydrocarbon, is chemically inert and is
highly resistant to a wide range of chemicals at ordinary temperatures.
It does not rot or absorb water. Polyethylene fibers have a high
resistance to acids and alkalids at all concentrations, but are
attacked by nitric acid. Insoluble in most common organic solvents
at room temperature.
Electrical
Properties
Polyethylene is an outstanding electrical insulator, especially
to high frequency currents.
Insects and
Micro-organisms
The fibers are not ingested by insects and are completely resistant
to bacteria, mildew and other micro-organisms, making them virtually
rot proof.
Effects of
Wind
Wind passes effortlessly through StealthNet, although smaller mesh
sizes are effected by wind to a larger degree.
Construction
Six strands of polyethylene, each 12/1000" (hence the name 12/6),
are wrapped rope-like into one strong, rot-resistant, U.V. protected
twine. With a breaking strength of 50 lbs per twisted strand, StealthNet
is the strongest polyethylene netting available in the world. StealthNet's
U.V.-treatment and color pigmentation are embedded in the composition
(not just dipped), making the net more resistant to the effects
of the sun with a more consistent coloring throughout. Flame-retardant
netting is now available through special order. Call for pricing
& specifications.
