PE mining tube flame retardant masterbatch

Characteristics: According to MT558.1-2005 standard, With PE80,PE100 grade of HDPE as the matrix resin,efficient compound FR and conductive carbon black as the functional additives,and the good dispersion of the homemade dispersing agent, the production is granulated by the twin-screw extruder. Be convenient to use and environment-friendly.It is the best choice for the FR for tube of coal mine gas/ventilation/drainage/shotcrete and antistatic pipe.Specification :( see attachment one)Standard: With the factory, all the results of the extrusion technology, processing prosperity, antistatic and fire resistance have passed by the special inspection agency.(see attachment two)The recommended extrusion process parameters (see attachment three).It should be some adjustment according to the processing applicants and the size of tube during the actual production.Storage: Handle with care. Cold storage. Keep air-tight and dry. Dry it before using after the long storage in the warehouse.After-service: We can supply the initial production and technical guidance. According to the requirements of the customer, we can send the technician to the factory.Package: 25kg paper-plastic composite bags and PP bags inner Attachment One: Technical Index:Items unit Test meth`od Standard Tensile Strength Mpa GB1040-06-V50 13 min Bending Strength Mpa GB9341-2008 12 min Flexural Modulus Mpa GB9341-2008 325 min FR Properties -- MT558.1-2005(MT181) Melting flow rate g/10min GB3682-2000(190?,5kg) 0.3-0.8 Surface Resistivity O*m MT558.1-2005(MT181) 106 min Density g/cm3 GB/1033-86 0.98-1.03 Applied usage area coal mine gas/ventilation/drainage/shotcrete and antistatic pipe.
