Non-crosslinked PP Foam Sheet and Engineer...

    PP Foam Sheet - Introduction Manufacturing Method for Non-Crosslinked PP Foamed Sheet As a manufacturing method for foam products, chemical foaming method has been used which suppressing foaming in the cylinder by maintaining high pressure by supplying resin compounded with foaming agent and extruding at the exit of workstation. However, high expended products can not be manufactured.There is also a physical foaming method that infusing organic compounds such as butane   pentane into the resin in the extruder, and foaming by extruding them at the worktable.This method  is possible to obtain more expanded products because organic compounds have high  chemical affinity and solubility with resin. However, because of high inflammability and explosiveness, its method is dangerous and requires careful operation of the facility and demands  explosiveness, its method is dangerous and requires careful operation of the facility and demands  high cost to secure high safety using anti-explosive facility. On account of this reason Pron-family gas and inactivated gases such as CO2 and N2 due to the issue of an ozone layer had been used instead of such organic compounds, However, these kinds of    gases have less chemical affinity and solubility than those organic compounds, so it is not likely    to get evenly dispersed foam and its diameter comes larger than normal.  The purpose of our business is to manufacture foam products using improved technique on    extruding chemical foaming with high power, small diameter, and evenly-dispersed foam, furthermore, excellent  in appearance.    Application The following list suggests only a few fields across a wide range of industries   -Food packaging   -Transportation   -Furniture   -Electronics   -Agriculture   -Construction   -AutomotiveAdvantages of PP Foam  -Environmental benefits: low material utilization and recyclability.   -High service temperature for microwavable packaging and automotive under-the-hood applications   -Moisture barrier   -Foam touch and appearance, insulative properties   -Excellent thermoformability over a wide range of densities   -High energy absortion properties   -Higher heat resistance   -Low density, Light weight    Specification of non-crosslinked foam sheet (PP,PE)  a.
