WintersChoice BioTM blankets are constructed of 70% Natural Straw fibers and 30% coconut fibers stitched <br />between two biodegradable jute nets using high tensile biodegradable thread. Our blankets are designed to <br />protect against erosion by providing temporary ground cover while einhancing seed germination and assisting <br />with vegetation establishment. <br />Functional longevity is up to 24 months depending on product used and site conditions, Soil erosion is controlled <br />by the root system, stem and leaf structure of the mature vegetation after the blankets degrade, <br />WlntersCholce BioTM Double Net blankets are rated for medium -flow channels and up to 2.16 lbs/ ft= shear <br />stress. Additionally, our blankets have a design C- Factor of .35 and are typically appropriate for up to 1.5:1 <br />slopes. <br />Additional Phvsical Proverties as tested and observed: <br />Property <br />Test Method <br />Typical Values* <br />Mass per Ufvt Area <br />ASTM D 6475 <br />8.48 oz/yd' <br />Thickness <br />ASTM D 6525 <br />0.31 inches <br />Light Penetration <br />ASTM D 6567 <br />13.6 % <br />Water Absorption <br />ASTM D 1117 /FCTC -TASC 00197 <br />415% <br />Swell <br />ECTC Guidelines <br />55% <br />Resiliency <br />ASTM D 6524 <br />74% <br />MD Tensile Strength <br />ASTM D 4595 <br />201.6 lb /ft <br />MD Elongation <br />ASTM D 4595 <br />21.5% <br />TD Tensile Strength <br />ASTM D 4595 <br />160.5 lb /ft <br />TD Elongation <br />ASTM D 4595 <br />180/0 <br />ECTC Bench Scale Testing ** <br />Description of Test Method <br />Test Method <br />Results <br />FCTC Method 2 - Determination of un- vegetated <br />2 in.
