Black polyester strong webbing combining many of the benefits of both polypropylene and nylon but without the negatives. Polyester is Polyethylene Terephalate. WPE4 has a rougher texture than WPE1 and 2. Available in 20mm, 25mm and 40mm widths. Uses: due to its excellent resistance to sunlight it is ideal for outdoor use, it is a versatile fibre which has excellent properties for many applications. Use with 25mm or 40mm buckles and fixings. Breaking strength of 1000kg Very high strength tenacity (up to 10g/den) Elongation - up to 25% at breaking point Abrasion - excellent resistance (5 times that of polypropylene softer feel) Moisture - has a very low regain of 0.4% making it feel damp very quickly Temperature - the melting point is around 260 degrees C and will withstand temperatures above 180 degrees C for some time. It will lose some strength if kept at high temperature for extended periods. low temperature resistance is very good increasing in strength and reducing elongation. It is difficult to ignite and due to its tightly woven structure burns slowly Inert to most common chemicals Excellent colour fastness Rot, UV and mildew resistant Sold by the metre (in continuous lengths) or as a 50 metre roll
