The Plastics Today for the Technologies of Tomorrow

Lumber

Lumber and paper processing operations that use performance plastics instead of metal parts have longer wearing, less noisy, more reliable equipment that performs better. Clearly, plastics are a cut above the rest!

Did You Know?

Structural plastic lumber has been used to make about 1.5 million railway ties in the United States alone. Since each tie weighs about 200 pounds, that means roughly 300 million pounds of plastics have not ended up in landfills, won't choke marine life and won't soil beaches.

From saw tables and chipper spouts to conveyor flights and pulp bale press slides, performance plastics outperform metal across every stage of lumber and paper processing — self-lubricating, shock-absorbing, corrosion-resistant, and dramatically lighter than steel.

Applications

  • Lumber industry — saw tables, liners, hose wrap/saddles, bushing, bearings, rollers, sprockets, chain guides, safety windows, flange caps, wear rails, saw guides
  • Saw mills and planer mills — tipple gates, chain channel inserts, wear plates/strips, bearings/blocks, sound dampeners, chipper spouts, drop grate arms, conveyor flights, hooks, slider blocks, diverter arms, chain caps, chip screens
  • Pulp and paper industry — bearings, bushings, conveyor parts, sprockets, liners, seals and rings, deflector blades, forming boards, pulp bale press slides and protectors, paper wedges
  • Protects hoses, wires and cables from rubbing, crushing and kinking

Advantages May Include

  • Cost efficient

  • Wide temperature resistant range
  • Easy to install and replace
  • Faster flow over screens
  • Fewer hang-ups
  • Lightweight
  • Low coefficient of friction
  • Lighter than steel; outlasts rubber
  • Requires less power to operate
  • Handles pressure and friction well
  • Impact and abrasion resistant
  • Minimizes product damage
  • Shock absorbing
  • Extends equipment life
  • Corrosion resistance to corrosion, rotting, rusting

Materials

  • Acetal (POM)
  • Chlorinated Polyvinyl Chloride (CPVC)
  • Fluorinated Ethylene Propylene (FEP)
  • High-Density Polyethylene (HDPE)
  • Low-Density Polyethylene (LDPE)
  • Nylon/Cast Nylon (PA)
  • Polycarbonate (PC)
  • Polyurethane (PU/PUR)
  • Polyethyleneterpthalate (PET)
  • Polytetrafluoroethylene (PTFE)
  • Thermoset Polyesters and Phenolics
  • Ultra-High Molecular Weight Polyethylene (UHMW-PE)

Sustainability Advantages of Performance Plastics

Cast nylon requires approximately 75% less lubrication and has a longer chain life than other materials when used in chain beds and liners in sawmills — cutting maintenance time, costs and lubricant waste.

2–4x
vs bronze & Babbitt

Plastics outwear materials such as bronze and Babbitt by 2–4x in applications such as wear guides, bushings, sprockets and more — improving productivity and reducing costly downtime across sawmill operations.

Sprockets made from performance plastics are up to 50% lighter and significantly quieter than comparable steel sprockets — reducing machine noise levels and energy consumption in sawmill environments.

50%
A UHMW tang conveyor flight is just 50% the weight of cast steel — delivering the same structural performance at half the weight, reducing drive energy and wear on conveyor systems.

Nylon sheaves are ¼ the weight of steel, yet offer load bearing capabilities up to 4,000 psi and compressive strength of 15,000 psi — exceptional strength-to-weight for hoisting and rigging applications.
