Over a decade of dedication, building a leading position in PVA foam materials
Nanjing Mianmian New Material Technology Co., Ltd. has been deeply engaged in the PVA foam materials field for over a decade. Through long-term technology accumulation and continuous innovation, we have grown into an innovative new materials enterprise integrating R&D, production, sales, and technical services.
The company independently masters multiple core production technologies including starch foaming, ultra-high-speed shear foaming, and air foaming. Building upon the absorption of international advanced PVA foaming technologies, we insist on independent R&D and process upgrades, forming industry-leading scalable, high-quality manufacturing capabilities.
We maintain long-term collaborative industry-university partnerships with Shanghai Jiao Tong University, Changzhou University, and other leading institutions, providing solid support for technology iteration and cutting-edge innovation, ensuring our core technologies remain at the forefront of the industry.

Independently mastering multiple core production technologies, driving industry development
Using natural starch as a sacrificial phase template, enabling precise control of pore size distribution (5μm–300μm) with porosity of 60%–90%. Products feature natural biocompatibility, widely used in medical nasal hemostasis sponges, ophthalmic dressings, and other medical devices.
Self-developed high-speed rotary shearing equipment (3,000–15,000rpm) forming precision structures with highly uniform pore sizes (CV<8%). Suitable for semiconductor wafer cleaning brushes, LCD panel cleaning rollers, and other high-end precision cleaning applications.
Uses no chemical blowing agents — green, eco-friendly, and zero harmful residues. Porosity adjustable from 50%–85%, with liquid absorption rates up to 10–15 times. Suitable for household cleaning, cosmetic care, food contact materials, and more.
