Fiberglass Snow Pole Properties

Composites

Fiberglass properties and test procedures of fiberglass reinforced iso-polyester marker posts and rectangular snow poles with ultra violet light inhibitor are as follows:

Thermomechanical deflection temperature per TMA modified ASTM D3418 = 70 degrees C
Fiber content by weight = 60% minimum
Density per ASTM D792 = .060 lbs./li.3
Barcol hardness per ASTM D2583 = 55 minimum
Water absorption per ASTM D570 = .05% (wgt increase after 24 hr immersion)

Fiberglass reinforced composites, utilizing a continuous molding process called pultrusion.
