• Heavy-Walled Plastic Cores for High-Pressure Applications

    Mesh Cores & Cages for Filter ElementsIndustrial Netting produces extruded polypropylene tubes that are typically used as center core supports or outer cages for cartridge filters. We have nearly 100 configurations of diameter, wall thickness and open area, including several options with thicknesses greater than 0.20” for high-pressure environments.

    Most cores are made from polypropylene resin that complies with FDA regulations for food contact. Polypropylene also holds excellent chemical and temperature resistance, so it works well in most any air, liquid or gas separation and filtration application.

  • PTFE Netting for Extreme Environments

    ET8900Expanded PTFE (Polytetrafluoroethylene) mesh is an excellent option for environments where other resins will fail. Whether facing extreme temperatures or highly caustic applications, PTFE provides superb chemical and temperature resistance.  Among the many advantages PTFE can provide are:

    • Suitable for use from -100°C (-148°F) up to 260°C (500°F)
    • Excellent chemical and solvent resistance
    • Non-toxic and inherently UV stable (UV radiation passes straight through causing no interactions).
    • Low-friction, high anti-adhesiveness
    • High dielectric properties
    • Made from resin that complies with FDA regulations for food contact

    Square MeshThe Extrusion Process

    Extrusion is a continuous process, in which plastic resin pellets are melted and pushed through a die in "meat-grinder" fashion.   Strands are formed as resin exits the die.  The hot matrix is then drawn over a mandrel and into a water bath to cool the netting.

    Types of Plastic Netting

    There are fundamentally two different kinds of extruded plastic netting differentiated by strand structure and the hole configuration formed by those strands: diamond netting and square netting.  Each is created through unique processes that result in distinct product characteristics.   Both types of products are produced in a wide range of configurations, ranging from fine "filtration-grade" netting that would resemble a woven product, to more course extrusion typical of plastic construction fence.

  • Replacing Metal with Plastic Mesh Yields Many Advantages

    Mesh Cores & Cages for Filter ElementsA hallmark of any successful manufacturing company is the constant pursuit of advantages and efficiencies in its processes and products. Buzzwords like “streamlining” or “continuous improvement” can sometimes be dismissed as business jargon, but meaningful changes that can favorably impact efficiency, productivity and, ultimately, costs are constantly at a premium. Those that can effectively impact these areas differentiate themselves from their competition and are more profitable.
