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).

    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.

    Biodegradable foaming plastic eco-friendly products

    Plant Origin

    Unlike the usual petroleum-based plastic, we use Polylactic Acid (PLA) resin which originated from corns, potatoes, or other starch.

    Carbon Neutral

    Both resin material and foaming agent are non-petroleum oil and don’t produce excess CO2 during the decomposing process.


    Contain many microorganisms just like compost, the plastic decomposed into water and carbon dioxide for about one week in a high and humid temperature environment.

    Use Low
    Load Foaming

    We use safe and low-cost gas with a small global warming potential as a foaming agent.

    Eco-friendly plastic
    for human and the world

    Plasteco has succeeded in foam molding biodegradable Polylactic Acid (PLA) resin which was considered difficult using the unique Supercritical Inert Gas Foam Molding Technology. Our company’s foam sheet is 100% biodegradable without using chemical foaming agents and inclines with the global interest in the plastic waste problem, used for a wide range such as food trays, packaging materials, and medical products that eco-friendly.
    Since we have a vacuum forming machine for testing and molding, we could make a prototype from sheet to mold.

    Aiming for the ultimate Eco-friendly plastic products

    Global Gas Warming


    Our company’s unique Supercritical Inert Feeder Gas Foam Molding Technology doesn’t use hydrocarbon-based foaming materials with high global warming potential. Also, by using plant-based raw material and non-petroleum inert gas foaming material, we have achieved “Carbon Neutral” that doesn’t cause excessive CO2 during the manufacturing and decomposing process.

    Plastic Waste Problem


    Plasteco’s foam sheet used 100% biodegradable resin that decomposed naturally in an environment that contains many microorganisms for about one week. Also, we have been researching Marine decomposability of resin, developing new plastic products that contribute to the resolution of plastic waste in the ocean

    Plasteco has been conducting cooperative research about plastic products related to environmental and resource problems and researching manufacturing methods. Although the petroleum resin used is gradually restricted, the biodegradable and completely nonpetroleum-based foamed plastic products born from the research are advanced materials and safely used in the future.
