Foam Technology for Highly Functional Products

Plasteco contributes to develop highly functional products with our environmentally friendly technology.
Plasteco propose a system optimized for foaming at low cost by constructing a global system.

We have a test facility, it is possible to test foaming of the desired resin.

    Safe and Ecological Foaming Agent

    • No-need for explosion-proof facilities: Unlike hydrocarbon-based foaming agents, our foaming agent is non-explosive.
    • Ecological: With its low GWP coefficients, our foaming agent is ecological compared to hydrocarbon-based agents.
    • Superior recycling efficiency: Unlike chemical foaming agents, our foaming agent contains no poisonous residue.

    Supercritical inert gas foaming enables:

    • Formation of cells just a few μm in diameter
    • Production of highly foamed crystalline resins — difficult with conventional foam technologies
    • High added value, such as optical performance, by controlling cell diameter

    Total Technical Support

    • Plasteco thoroughly supports the development of raw materials, operation processes, and equipment.
    • Supercritical Inert Gas Feeder (PLASTECO2) can feed carbon dioxide, nitrogen, and other inert gases.
    • Our standard lineup of foam molding machines includes extruders and reaction injection molders (RIM).

    • For superior high-frequency property : low dielectric constant
    • For fine elastomer foam products
    • For fine and smooth surface : controllable skin layer
    • For making independent or interconnecting cells
    • For complicated structural design with no sink-mark
    • For shortening forming cycles/li>
    • For avoiding environmentally harmful foaming agents
    • No need for explosion proof facility
    • Inexpensive foaming agent

    Supercritical Inert Gas Foam Reaction Injection Molding

    Supercritical Inert Gas Foam RIM is the microcellular foam technology that dissolves inert gases such as CO2 into resin and produce microcellular foam by suddenly change its pressure and temperature.

    The technology enables to produce foamed products made of PU and DCPD. This environmentally friendly technology uses supercritical CO2 as a foaming agent and can contribute to develop sophisticated highly functional foam products such as high heat conductivity and low dielectric constant.

    Quantitative Supercritical Inert Gas Feeder

    Quantitative supply technology that responds to instant pressure fluctuations

    PLASTECO2 enables extremely precise supply of foaming agents that conventional pumps cannnot achieve.

    PLASTECO2 is a quantitative gas feeder developed specially for supercritical inert gas foam molding.

    Highly precise gas supply to any foam molding

    Because of the low solubility of carbon dioxide and nitrogen in resins, slight fluctuations in gas supply have a large effect on the foaming conditions.

    PLASTECO2 ensures precise gas addition by automatically synchronizing the addition pressure with the pressure in the molding machine.

    For quantitative addition of various inert gases

    PLASTECO2 can be used to add various inert gases such as supercritical carbon dioxide and nitrogen.

    PLASTECO2 systems can supply gas in micro to large amounts.
    Standard models provide gas at supply pressures of 15 MPa and 25 MPa. Higher pressure models are also available.

    For purposes other than foam molding

    Demand is growing for supply of supercritical inert gases other than for foam molding.

    We can manage requests for various options, allowing customers to employ PLASTECO2 for a wide variety of uses.

    Ultra Light PET Bottle Filling System

    Different from reuse and recycle : Ultimate solution to supply safe and ecological beverages to the people in the world

    A 330-ml Ultra Light Bottle which Plasteco made weighs only 7 g, half the weight of an ordinary bottle.

    Capacity 300ml Weights only 7g
    • For reducing the conventional bottle weight by half = 7g(300ml)
    • Easily crushed = Reducing the collection cost of empty bottles.
    • Filling and mouth sealing processes are completed under an aseptic condition right after molding bottles = Rinsing water is unnecessary.
    • Printable bottle surface = Bottle label might be omitted.
    • Total technical support = Plasteco designs consistent bottle filling lines including blow molding machine, filling, printing and labeling equipment.
    • Compact set-up of the equipment = Applicable to produce small quantity, large variety beverages for the local consumption.
    • Remote control of the equipment by the Super Vision System.
