With technology innovation as our core driver, we independently master starch foaming, ultra-high-speed shear foaming, air foaming, and other core production technologies. Building upon the absorption of international advanced PVA foaming technologies, we persist in independent R&D and process upgrades, continuously breaking through key technical bottlenecks, optimizing production processes, and significantly improving production efficiency and product performance, forming industry-leading scalable, high-quality manufacturing capabilities.
Supported by a comprehensive technology system, we have built a full industry chain solution covering medical devices, cleaning, water absorption, filtration, and other fields, deeply empowering the domestic substitution of high-end medical devices, high-end semiconductor/electronic cleaning brushes, industrial and household cleaning rollers, and other premium application scenarios.
We always uphold the business philosophy of "Quality First, Win-Win Development", driven by continuous technological innovation and rooted in premium manufacturing, to provide global clients with high-performance products and integrated solutions. We are committed to becoming a trusted long-term partner in the PVA foam materials field.

Quality First, Win-Win Development — Our Business Philosophy
Independently mastering multiple core production technologies, driving industry development
Precise control of pore size distribution 5μm–300μm, porosity 60%–90%, with natural biocompatibility, widely used in medical devices.
Self-developed 3,000–15,000rpm high-speed shearing equipment, pore size CV<8%, suitable for semiconductor wafer cleaning and other high-end precision applications.
No chemical blowing agents, green and eco-friendly with zero residue. Porosity adjustable from 50%–85%, liquid absorption rates up to 10–15 times.
Unique porous network structure enabling fast liquid uptake
Water absorption up to 10–20 times its own weight
Precision foaming process ensures stable structure with no residue
Full-process quality control ensures minimal batch-to-batch variation

Dual certification, full-process quality control

We use imported premium PVA raw materials throughout our production, controlling product quality from the source to ensure stability and consistency of the final products.
Equipped with high-precision intelligent production equipment imported from abroad, supporting technology implementation with advanced hardware to guarantee production precision and efficiency.
We have established a comprehensive quality control system covering R&D, production, and inspection, strictly implementing both ISO9001 and ISO13485 quality standards to ensure product stability and consistency.
With strong R&D capabilities and continuous technological innovation, our PVA foam sponges feature rapid liquid absorption, high absorption capacity, lint-free operation, and consistent performance — reaching internationally advanced levels and capable of full import substitution.
