In the field of 3D printing, the performance of zirconia ceramic inks is crucial. As a nonionic dispersant, polyvinylpyrrolidone (PVP) works in concert with ammonium polyacrylate (PAA-NH4) and can significantly improve the stability and rheological properties of the ink. Through the cooperation with PAA-NH4, PVP forms a stretched polymer configuration on the surface of zirconia particles, increasing the steric repulsion force, effectively preventing particles from agglomerating, and making the ink dispersibility better. In 20vol% solid phase zirconia ceramic ink, 1wt% PVP and 1wt% PAA-NH4 were added simultaneously to obtain low viscosity and high stability ink. It was left to stand for 2 weeks at room temperature without obvious stratification. Ceramic inks using PVP perform well during inkjet printing. In the temperature range of 25°C to 60°C, the ink can form regular round ink droplets, which has strong adaptability. When the pulse voltage.When the pulse voltage is 120V and the operating frequency is 5000Hz, the ink droplet jetting morphology is ideal, ensuring printing accuracy.
PVP has shown great potential in the field of 3D printing ceramic inks, providing strong support for the high-precision printing of zirconia ceramics, and is an ideal choice for those who pursue high-quality printing effects.

Sunlydone K products are mainly used as film formers, but also as thickeners. The molecular weight determines the setting and adhesive properties of PVP polymers; the higher the molecular weight, the greater the setting. They are ideal for use in water-based applications where a high degree of clarity is required in the finished product (e.g. Gels). For hair-styling applications K30 and K85 are the best of the various molecular weights.
• Water-soluble in high concentrations to form clear solutions
• Form clear, homogeneous films
At low relative humidity the films are hard and brittle; at high relative humidity they are elastic and soft
• High water-absorption capacity
• Mixtures with polyacrylates, polyquats, salts, acids and bases are possible; high compatibility with many other cosmetic ingredients
• Nonionic, no neutralization required
Powder: 25/50 kg net in fiber drums
Solution: 60/150/200 kg net in PP drums or 1000kg IBC tank
Rich Experience
1992, Zhejiang Sunflower New Material Co.,Ltd. which was predecessor of STD, engaged in PVP, was set up and Mr. Wu Jiaxiang, the chief expert of the state's R&D project for PVP in China, was appointed as the general manager.
Advanced Equipment
2004, Zhejiang MY Sunflower Pharmaceutical Co.,Ltd. which is JV of STD was established for production of PVP in Pharm.Grade. GMP workshops were founded for POVIDONE, POVIDONE IODINE and POVIDONE IODINE SOLUTION.
Reliable Product Quality
2010, SPP expand the factory from 4000M2 to 12,000M2. After that the capacity of 3500tons of powder and 5000tons of liquid products annually till the end of 2011.
Professional Technical Team
Led by Mr. Wu Jiaxiang, the main PVP founder in China, the team possessed tens of concerned process and application techniques, gathered 35 years of experience of sustainable R&D, engineering practice and marketing.
Pharmaceutical field:
It is one of the three major new pharmaceutical excipients advocated by the international community. It can be used as a binder, cosolvent, flow aid, etc. It is also used in eye drops and contact lenses. It can detoxify and stop bleeding.
Food industry:
It is safe and can be used as a clarifier and stabilizer for beer, fruit juice, etc. Cross-linked PVP can stabilize beer and reduce the cost of tea beverages.
Cosmetic field:
It accounts for 70% - 80% of consumption in my country and 30% - 50% in developed countries. It can be used as a setting agent, sunscreen, etc. to enhance the moisturizing and lubricating effect of skin care products.
