QD-PLB Bitumen Bag Features and advantages 1)High temperature resistance, oil proof, water proof, non-toxicity, be completely fused with asphalt by mechanical agitation, high bearing stress strength and so on. 2)weight, small size,the lowest cost. 3)Convenient in use, transportation and storage. 4)Contain Polyolefin which is a addition agent of building asphalt,modified asphalt and can improve impact resistance and toughness of asphalt. 2.Specification 25kg: Internal bag:800×500(±10mm) and externalbag 750×480 (±10mm) 40kg:Internal bag:950×580(±10mm)andexternal bag 900×560(±10mm) Packing bags could be processed according to thickness and standard dimensions of contract requirements. QD-PLB-1 high temperature packing bag for asphalt must be used by being mated with external woven plastic bag. For details of external woven bag dimensions, please check appendix. 3.Quality Index ItemPerformance Index25kg40kgTensile strength ofMaterial MPaLongdirection20Horizontal 22MaxTemperaturedegree celsius140 Use Temperaturedegree celsiusless than 135 Meltde temperature 160-170degree celsiusAsphalt and packing bags completely melted with 20min when agitating( agitating speed more than 80r/min).
