The PVA sponge, made from Polyvinyl Alcohol, is a high-performance synthetic material with an open-cell structure designed for superior absorption. Its porous nature allows it to quickly draw in aqueous solutions. The sponge is compressible when dry, expands when wet, and exhibits excellent tensile strength, elongation, and resistance to a wide range of chemicals.

Being hydrophilic, the PVA sponge can absorb up to 12 times its dry weight in water. The cell size can be tailored to suit specific needs, with finer cells providing enhanced capillary action. In its hydrated form, the sponge tolerates temperatures up to 70°C, while in its dry state, it can endure temperatures reaching 100°C.

What are the benefits of PVA Sponge?

PVA Sponge is hydrophilic and can hold upto 12 times its dry weight in water

Cell size can be varied depending on the required capillary actions

The wet spnge withstands temperatures nearing 70°C and the dry about 100°C

Polyvinyl Alcohol (PVA) Sponge is a high-tech synthetic sponge known for its extraordinary absorbency and durability. Unlike traditional sponges made from cellulose or polyurethane foam, PVA sponges have a unique open-cell structure that is fully hydrophilic (water-loving). This means PVA sponge material actively absorbs and holds water and other liquids without dripping. In fact, a PVA sponge can soak up 12–16 times its own weight in water, making it one of the most absorbent materials for its weight class.

Advanced Air-Foamed PVA Technology

At Lotus Prime, we specialize in the production of high-performance and ultra-clean air-foamed PVA sponge materials—a technology mastered by only a select few globally. Our PVA foam features a fully interconnected pore structure, allowing us to fine-tune porosity and softness for specific applications. Manufactured using ultra-clean processes, our foam offers outstanding cleanliness, fluid control, and skin compatibility, making it an ideal upgrade over traditional cotton and starch-based sponges in medical and hygiene environments.

Our advanced PVA foam not only meets the rigorous demands of Medical, but also shows exceptional promise in many applications in field of Aerospace, Automotive, Clean-Room, Filtration, Beauty & Cosmetics, Electronics & Semiconductor, etc. Its purity, absorbency, and durability make it a versatile material for industries that require precision, hygiene, and reliability. With our unique manufacturing technology and capability, Lotus Prime the supplier of choice for PVA sponge products with below some key characteristics:

  • Unmatched Absorbency: PVA sponges are extremely hydrophilic, capable of absorbing up to 12-16 times their dry weight in water. This means faster, more efficient drying and cleaning for your applications.
  • Lint-Free & Clean: Our sponges are naturally lint-free and static-free, ensuring no fibers or dust are left behind. This makes them ideal for sensitive environments like cleanrooms, medical facilities, or high-precision manufacturing.
  • Durable & Reusable: Engineered for strength, PVA sponges have excellent mechanical integrity and abrasion resistance even when wet. They can be reused many times and are easy to clean (machine washable in most cases), offering a cost-effective solution over disposable wipes.
  • Chemical Resistant: PVA material resists degradation from most common chemicals – including dilute acids, bases, and solvents – allowing our sponges to perform in harsh cleaning agents or sterilization processes without breaking down.
  • Customizable Solutions: As a manufacturer, we can tailor sponge size, shape, pore structure (cell size), and other properties to your requirements. Whether you need a special shape for a new device or a specific absorbency level, we have the design and development capability to deliver.

In summary, Lotus Prime’s air-forming PVA sponge is a modern material that combines the best qualities of a sponge (absorbency, softness) with the robustness required for industrial and medical applications. It’s this combination of properties that makes it the material of choice for Lotus Prime’s range of advanced PVA sponge products.
