Siloxane content





  • SiSiB® SP1070 siloxane powder is widely used to improve the lubricity and surface quality of plastics.

  • SiSiB® SP1070 can be used in modification of plastics, cable compounds, elastomers, thin-walled complicated parts, silicone core pipe, and plastic pipe etc.

  • SiSiB® SP1070 can be used in low smoke flame retardant PVC compounds and rigid PVC compounds.

  • SiSiB® SP1070 can be used in high temperature engineering plastics, which can improve the flow of the silicone resin and processing properties, promote the crystallization of PA, improving the surface smoothness and impact strength.

  • SiSiB® SP1070 can improve the surface finish without any bleeding when it is used in engineering plastics sheets.

  • SiSiB® SP1070 can be used to improve dispersion properties and make the surface more slip, prevent pigments reunion etc.

  • Use methods:

    Silicone molding/pelleting process is necessary for better performance when SiSiB® SP1070 mixed with the other materials at a certain proportion.

  • Recommend dosage:

    It can improve the product’s processing, liquidity and mold release when it is added at 0.5%-2%. At a high level, 1% to 5% can improve the surface properties (smoothness, finish, scratch resistance and abrasion resistance).

Packing and Storage

  • SiSiB® SP1070 is supplied in 25Kg craft paper bag.

  • In the original unopened packaging, SiSiB® SP1070 has a shelf life of 24 months at dry condition, room temperature.
