Introduction  

    This masterbatch is mainly made up of superfine inorganic powder with high quality, mixed with carrier resin and related modifying agent and manufactured with special device and technology; with good dispersity on matrix resin, good spinnability, low filter pressing value, long period for pallet, large volume of addition and good processing performance, it is a kind of modified material specially applied to filling for spunbonded nonvenfabric with reduced cost. 

  Range of application 

    Modified filling for spunbonded nonwoven fabric material.

  Usage

    In general, the traditional production technology can satisfy requirements for this masterbatch, so the device and production technology shall not be replaced during detailed production. That is to say, mix with the matrix resin as per certain percentage, stir uniformly and feed. Recommended percentage of addition: 1%-40% (weight ratio). For detailed amount of filling, depend on the performance requirements for final product.

  Packaging and store

    Double-packaging, paper-plastic lamination for external surface and water-proof and damp-proof polythne film bag for internal surface. The net weight is 25KG/bag. It shall be stored in the dry place with good ventilation, low temperature and away from light. Be attention to preventing water and damp. The product performance may be affected by the moisture, so it shall be run out as soon as possible after opening the package. The guarantee period under sealed storage condition is 4 months.
