Developed in 1974 using Sekisui Kasei's proprietary polymer hybrid technology, PIOCELAN is a unique foamed resin that has a highly optimized combination of polystyrene and polyolefin properties: "rigidity, expandability, heat insulation" and "impact resistance, chemical resistance, wear resistance".
Conventionally, polystyrene has excellent rigidity, expandability, and heat insulation properties, but it has weaknesses in "impact resistance, chemical resistance, and wear resistance". Sekisui Kasei has compounded polyolefin with this polystyrene. By combining the properties of both materials, new applications have become possible.
Since its development half a century ago, the opportunities to use the ever-evolving PIOCELAN have been expanding due to its high convenience and excellent environmental adaptability.
PIOCELAN offers outstanding impact resistance performance. By selecting the appropriate grade and customizing material properties during the design stage, it is possible to achieve the optimal balance between performance, weight, and cost.
These characteristics make PIOCELAN ideal for applications requiring impact absorption. In automotive impact absorbers, it helps reduce the force exerted on occupants and pedestrians in the event of an accident, thereby enhancing safety. It is also widely used as cushioning and protective packaging material for precision equipment and high-tech products, protecting them from external impacts and vibration during transportation.

Compared to conventional polypropylene and polystyrene, PIOCELAN has superior overall mechanical properties and exhibits high dimensional stability during molding. These properties enable precise and complex designs and styling in fields where the use of foamed resins was not previously envisioned.
Since automobiles move and are subjected to vibrations both internally and externally, any gaps between parts or inadequate dimensions can cause chattering and creaking noises. These problems can be solved by the high dimensional stability and rigidity of PIOCELAN.
PIOCELAN is a unique foamed resin that is a composite of polystyrene and polyolefin. By adjusting various physical properties using Sekisui Kasei's proprietary polymer hybrid technology, it is possible to customize PIOCELAN beyond its basic properties to provide extremely high impact absorbability or flexibility suitable for extremely complex shape designs.
In addition, a variety of grades are available to meet application requirements, including grades with antistatic properties for packing electronic components.
Furthermore, our technical team with years of design know-how and a thorough knowledge of PIOCELAN will select the most suitable grade and propose customization to meet your needs.
Conventional expanded polystyrene is subject to scraping, chipping and denting due to wear, but PIOCELAN, with its superior wear resistance, overcomes this weakness.
In addition, PIOCELAN is "returnable" (reusable) due to its high dimensional stability and excellent impact resistance.
When used for applications such as packing materials for use in transportation, it is possible to reduce costs and environmental impact with this excellent anti-wear performance through multiple returnability, which was difficult with conventional foamed resin packing materials.
The Sekisui Kasei Group has certified "packing materials for transporting automobile parts" and "flat-panel TV glass / panel transport containers", which are molded products using PIOCELAN, as "sustainable star products" * (environmentally friendly products).
Certification criteria established as part of the action plan "SKG-5R" to realize the "contribution to a sustainable society" set forth by the Sekisui Kasei Group (SKG). We internally certify products that reduce environmental impact and take into consideration limited resources as "Sustainable Products", and products that have a particularly high degree of contribution to the environment as "sustainable star products" (environmentally friendly products), thereby promoting their creation and market expansion.
In addition to the PIOCELAN lineup, PIOCELAN RNW has been introduced. PIOCELAN RNW contains 15% or more recycled materials and offers strength and physical properties comparable to those of PIOCELAN made from virgin materials making it an environmentally friendly product that helps reduce environmental impact.
PIOCELAN is more resistant to chemicals and oil than conventional expanded polystyrene, and is unaffected by adjacent members even if it is used for automobile parts or container transport containers where various chemicals and oils are nearby. As a result, PIOCELAN can stably demonstrate its original performance without being affected by adjacent parts.
The increase in cost, size, and weight that would have resulted from problems such as the need for a multi-layered structure to achieve a tight seal, and the need for a large spatial margin to reduce the impact of the system can be avoided.
