PIOCELAN is a composite resin foam that combines the advantages of polystyrene and polyolefins. It is a foamed plastic material with high rigidity, excellent impact resistance, oil resistance, and dimensional stability.

It combines the rigidity of polystyrene (PS) with the flexibility and impact resistance of polyolefins (PP/PE).

A high-performance material that offers the “best of both worlds” of PS and PP/PE.

PIOCELAN excels at absorbing impacts by leveraging its compression and bending characteristics, delivering high impact-energy absorption. In a penetration impact absorption comparison (15× expansion), it achieves about 1.4× that of EPS and about 1.1× that of EPP.

It offers approximately 30% higher rigidity compared to EPP at the same expansion ratio.

It meets the 80°C heat resistance standards required by major automotive OEMs.

A self-extinguishing grade compliant with the FMVSS 302 flammability standard is available.

It has low shrinkage during molding, and post-molding annealing is not required, making it resistant to deformation and excellent in dimensional stability.

Its closed-cell structure creates air layers within the foam, providing excellent thermal insulation.

It offers chemical resistance comparable to EPP against various chemicals, including alcohols, acids, and alkalies.

It has high oil resistance to gasoline, heavy oil, cleaning oils, and more.

Compared with EPS, it is less prone to cracking and offers superior impact strength. In addition, the olefin surface layer helps reduce squeaking/rattling noise and improves chemical resistance.

Compared with EPP, it offers higher rigidity, better impact absorption, and superior dimensional stability, while also reducing molding/processing costs.

It is easy to foam-mold and can accommodate complex shapes.

We offer environmentally focused product lines under the name “PIOCELAN 2.0,” including PIOCELAN RNW (made by collecting and recycling used PIOCELAN) and PIOCELAN LW for automotive parts, which increases the expansion ratio to 45× and enables about 30% weight reduction versus the conventional 30× grade.

It maintains FMVSS 302 self-extinguishing performance even at 35×/40×/45× (white) and 35×/40× (black).

Thanks to its high rigidity, LW enables weight reduction of about 14% (30×→35×), about 25% (30×→40×), and about 33% (30×→45×).

It is well suited for areas where weight reduction has a large impact, such as floor spacers, seat cores, lower-leg impact absorbers, and tool boxes.

Adoption has already begun on certain vehicle models. It can achieve 14–33% weight reduction compared with conventional products.

Even at 35× or 40×, it maintains compressive strength comparable to the conventional 30× grade.

It shows minimal dimensional change after 80°C × 168 hours, demonstrating excellent heat stability.

For both white (35×/40×/45×) and black (35×/40×), it is self-extinguishing and meets the FMVSS 302 requirements.

It is produced at SEKISUI KASEI group plants in Japan and overseas, and supplied from the optimal site depending on the application.

With more than 20 group companies and multiple molding plants, we can select the best site according to QCD requirements.

We have group sites in multiple regions—including North America, Europe, and Asia—enabling global supply.

Yes. We can supply materials and support molding at multiple locations worldwide.

We have extensive mass-production experience for automotive applications and can handle both large and small lots.

With our multi-site network, we can switch production as part of BCP measures.

We maintain stable supply through measures such as distributed production, inventory optimization, and diversified raw-material sourcing.

We provide end-to-end support—from material selection and prototyping to evaluation, tooling, and mass production.

Leveraging years of experience in automotive parts design, we can also support mold specification review and prototyping.

Our sales, engineering, and quality teams work together with customers in co-development.

The current RNW grade is a recycled grade made by collecting and reprocessing used PIOCELAN, offering performance comparable to virgin material.

At present, it is mainly applied to conventional grades, but expansion to other grades is being considered for the future.

Based on the SKG-5R strategy, we promote energy saving, recycling, and decarbonization.
