プラステコ List of Products and Services

Beads made from plant-derived, biodegradable resin PLA (polylactic acid) are foamed using a unique extrusion foaming technology developed by Plasteco, which utilizes low environmental impact inert gases (CO2, N2) and are then steam-formed into block and board shapes. They can be processed into your desired shape through cutting and other methods! They can be used as an alternative to traditional expanded polystyrene for packaging materials and cushioning, as well as for three-dimensional objects and display items. High expansion foaming with a safe and inexpensive foaming agent (inert gas) also allows for a reduction in raw materials! PLA resin, which has a high raw material cost, can be foamed and molded at a low cost.

This is a feeder that quantitatively supplies the main material (raw material) and auxiliary materials (additives, etc.) to the extrusion molding machine. It precisely controls the main feeder for the main material, the sub-feeder for the auxiliary material, and the gas (foaming agent), linking their respective addition rates. By combining it with Plasteco, a manufacturer specializing in inert gas foaming, extrusion molding machines, dehumidifying dryers with stirring, gas supply units, etc., it is possible to construct a "supercritical inert gas extrusion foaming system" that is more suitable for foaming.

Foamed PLA (polylactic acid) is a material with lower environmental impact than conventional materials such as foamed polystyrene and other foamed plastics, as it is plant-based and biodegradable. Additionally, thanks to Plasteco's unique supercritical inert gas foaming technology, there are no residues like those from chemical foaming agents, and it is foamed and molded using methods that have a low global warming potential, making it an environmentally friendly product from raw materials to molding processes. The fine bubbles of PLA (bubble diameter 10-30μm) and the independent bubbles provide excellent thermal insulation, moisture resistance, and antibacterial properties, while also preventing the occurrence of dust mites and other pests from the tatami base. It also has soundproofing properties, creating a comfortable living environment.
