Chemically and Physically Stable
Chemically and physically stable, Nolar polymer is inert and will not react with alkalies and most acids up to temperatures of 165°F. Impervious to water, moist materials will nt stick, which means that in freezing wearing, ice will not stick to Nolar polymer liner surfaces.
Low Friction Coefficient
Nolar Polymer anti-adhesive high-slip feature is demonstrated by a dynamic friction coefficient of 0.15 to 0.20 as measured against machined steel of 0.30 to 0.40. In practice, this means that on inclines as low as 10°, Nolar polymer liners will not impede flow of the finest coal particles regardless of how wet or cold it gets. |

Outwears stainless steel
Nolar polymer's upper slick, non-stick surface is matched by unequalled abrasion resistance. In actual tests, Nolar polymer lasts from 6 to 10 times longer than stainless steel at only one-half the cost.
Lightweight, easily handled
Nolar polymer, supplied in standard 4' x 10' sheet, weighs only 1/6 as much as stainless steel. Typically, a 1/4" sheet of nolar polymer, affording 40 sq. feet of protective liner surface, weights only 55 lbs, as opposed to s400 lbs. for stainless steel. This permits fast, easy field installation by a one- or two-man crew. |

Nolar panels are easily installed.
Nolar polymer is simple to install as a lining for bunkers and chutes. Panels are installed in the direction of material flow with provision for a minimum 2-inch horizontal overlap at the top and bottom. Fastening with pins, screws, or bolts is done throught hte overlap so that both the top and bottom of each panel are secured. |
The top edge of the initial course should be capped with a cover strip which can be bolted or fastened in place wtih screws. Vertical joints should butt edge-to-edge. If fine materials are handled, the vertical butt joints should be covered with Nolar polymer battens to prevent seepage. Corner butt joints can be similarly sealed by using angled strips
Special cap and angle shapes can be formed on the job using a propane torch or blowtorch with a fan tip. Nolar polymer can be heated evenly with the flame held 4-5" from the surface, taking care not to overheat. The heated section can be formed to the desired contour, and when cool will take a permanent set. Original physical properties are retained. Nolar polymer can also be welded and adhesive joined. Consult factory for details.
Nolar polymer liner panels can be handled in the field with outstanding ease due to their light weight. Band saw cutting is highly efficient, as the blade dissipates heat, permitting high cutting speeds without need for coolant.
The material may also be cut with a circular saw using a blade with a slight set to the teeth to prevent wedging. While cutting speed it limited by heat build up, higher cutting speeds provide a better surface finish. Wood or metal hand saws and sabre saw with wide-set teeth may also be used.
Installation to wood, metal, or concrete construction can be done by nailing, or fastening with bolts, screws, or percussive shot pins. Countersunk stainless steel flat head bolts or screws of 3/16" to 5/16" diameter, as well as carriage bolts, hex and button styles can also be used. In concrete bunker installations, stainless steel shot pins with washers are recommended. |

For use as scraper blades and guides, Nolar polymer may be drilled and countersunk using portable power or hand tools.
Available in Standard Sizes: 1/8" through 2" thickness; 48" x 120" sheet size; rounds and flats available on request.
