In the vast hierarchy of synthetic materials, few ascend to the summit occupied by Polyphenylene Sulfide (PPS). Often referred to as "Plastic Gold," this moniker is not merely a reference to the amber hue of the raw resin, but a testament to its irreplaceable value in modern engineering.
While standard plastics are mere commodities, PPS stands as a strategic asset—a "Super Engineering Plastic" designed not for convenience, but for survival in conditions where metals prove too heavy and other plastics simply disintegrate. This material thrives where others fail, making it the material of choice for humanity's most demanding applications.
The reason for its "extreme" nature is fundamentally a perfect alignment between PPS's ultra-high performance and the most challenging application scenarios—a true reflection of its high value and formidable technical barriers.
PPS application scenarios push the boundaries of what both ordinary plastics and even metals can withstand. Its semi-crystalline structure creates an impenetrable fortress against the three great adversaries of materials: extreme heat, aggressive chemicals, and electrical stress.

Engineering Standard: PPS achieves UL94 V-0 flame retardancy intrinsically without additives—critical for high-voltage electronic components and automotive applications.
Due to its deployment in mission-critical applications, the processing and utilization of PPS demand absolute excellence. This is not a material for casual manufacturing—it is reserved for those who master the art of precision engineering.

The paradox of PPS is clear: it is difficult to process, demanding in application, and requires significant investment—but in those scenarios where no alternative exists, it remains the only viable solution.
If PPS is so demanding, why do we persist in utilizing it? Because in those domains where compromise is not an option, PPS delivers the optimal solution that no other material can match.
The combination of PPS's "demanding application requirements" and its "exceptional performance" creates an insurmountable barrier for low-end competitors. This is a high-tech, high-barrier, high-value-added market segment where true engineering excellence determines the victors.
How do we reconcile supreme performance with environmental responsibility? The answer lies in our flagship innovation that bridges both worlds.
Parpus® rPPS represents the pinnacle of sustainable engineering materials. Produced from recycled post-consumer products (sources including, but not limited to, dust filtration bags and electronic/mechanical components), our PCR PPS undergoes rigorous pretreatment and standardized compounding processes to deliver injection-grade recycled PPS pellets.
Through meticulous source control, technological innovation, and performance optimization, we deliver a material that maintains nearly 100% of the mechanical and thermal properties of virgin resin—while dramatically reducing carbon footprint and supporting circular economy principles.
