Extruded polycarbonate sticker for spacing wood

A sticker for spacing wood comprising:

• an extruded body made of an alloy of polycarbonate resin, 10-20% polysulfone resin by weight, 1-2% carbon black by weight, and 10-20% of glass fibers by weight, the extruded body comprising:
• a plurality of substantially hollow longitudinal internal chambers;
• a top surface comprising:
• a first plurality of longitudinal ridges that provide a first contact area having a first area substantially smaller than a total area of the top surface;
• a first plurality of longitudinal grooves between the first plurality of longitudinal ridges;
• and
• a first plurality of lateral grooves running substantially perpendicular to the first plurality of longitudinal grooves to provide a knurled top surface comprising a first plurality of bumps in a first plurality of rows along a length of the top surface;
• a bottom surface comprising:
• a second plurality of longitudinal ridges that provide a second contact area having a second area substantially smaller than a total area of the bottom surface;
• a second plurality of longitudinal grooves between the second plurality of longitudinal ridges;
• and
• a second plurality of lateral grooves running substantially perpendicular to the second plurality of longitudinal grooves to provide a knurled bottom surface comprising a plurality of bumps in a plurality of rows along a length of the bottom surface;
• wherein the tensile break strength of the extruded body is at least 9,000 pounds per square inch (PSI) (62.1 megapascal (MPa));
• wherein the elongation of a sample of the extruded body at break during a test of the tensile break strength is 110-130%;
• wherein the flexural strength of the extruded body is at least 13,500 pounds per square inch (PSI) (93.0 megapascal (MPa));
• wherein the flexural modulus of the extruded body is at least 350,000 pounds per square inch (PSI) per minute (2.41 gigapascal (GPa) per minute);
• wherein the modulus of elasticity of the extruded body is 350,000 PSI (2.41 gigapascal (GPa));
• wherein the compressive strength of the extruded body is at least 12,500 pounds per square inch (PSI) (86.2 megapascal (MPa));
• wherein the Izod impact strength of the extruded body is in the range of 12-16 ft-lb per inch (640-850 Joules per meter);
• wherein the melt flow index of the alloy is from 3 to 6;
• and
• wherein the specific gravity of the extruded body is 1.22 to 1.3.
