The P300 is sewn together using UV stable <br />polypropylene thread stitched on 1.50 inch (3.81 cm) centers. The mat is highly resistant to ultraviolet and <br />biological degradation. The following list contains further physical properties of the P300 erosion control/turf <br />reinforcement mat. <br />Pro a Test Method <br />Thickness ASTM D6525 <br />Resiliency ASTM D1777 <br />Density ASTM D792 <br />Mass per Unit Area ASTM D6566 <br />Porosity ECTC Guidelines <br />Open Volume per Unit Area ECTC Guidelines <br />Stiffness ASTM D1388/ECTC <br />Light Penetration ECTC Guidelines <br />UV Stability ASTM D4355 <br />MD Tensile Strength ASTM D6818 [D5035] <br />MD Elongation ASTM D6818 [D5035] <br />TD Tensile Strength ASTM D6818 [D5035] <br />TD Elongation ASTM D6818 [D5035] <br />Typical <br />0.54 in (13.72 mm) <br />91.50% <br />0.513 oz/in3 (0.890 g/cm3) <br />11.46 oz/yd2 (389 g/m2) <br />95.89% <br />872 in3/ydZ (11,952 cm3/mZ) <br />97.24 oz-in (1,085,378 mg-cm) <br />15% <br />90 <br />4811bs/ft (7.02 kN/m) [3791bs/ft (5.53 kN/m)] <br />20 % [26 %] <br />4261bs/ft (6.22 kN/m) [4031bs/ft (5.88 kN/m)] <br />23 % [27 %] <br />**ASTM D1682 (4 inch strip) Tensile Strength and % Strength Retention of material following 1000 hrs exposure in xenon-Arc Weatherometer. <br />MD -Machine direction <br />TD -Transverse du+ection <br />n..~..L C~....1..

These tests are not indicative of field performance and therefore should <br />not be used in design to establish performance levels for rolled erosion control products. Bench scale tests are <br />performed according to methods developed by the Erosion Control Technology Council (ECTC). <br />Updated 1/2004 <br />
