Polivinilpirrolidone, also known as polyvinylpyrrolidone (PVP), is a water-soluble polymer synthesized from N-vinylpyrrolidone monomer. It is a white to off-white powder with high chemical stability and good physiological compatibility. It is soluble in water and a variety of organic solvents and has strong hygroscopicity. It is often classified by K value according to the average molecular weight. The larger the K value, the higher the viscosity and the stronger the adhesion.
Application Areas
01
Medicine:
used as tablet adhesive and coating material to help molding and moisture-proof; used as liquid preparation cosolvent and stabilizer to promote dissolution and dispersion; used to prepare film and gel, such as povidone iodine disinfectant.
02
Cosmetics:
used as a shaping film-forming agent in hair spray and mousse; used as a film-forming, thickening and moisturizing agent in skin care products to form a protective film, adjust the texture and moisturize.
03
Industry:
used as a dispersant and thickener in coatings and inks to improve the dispersion of pigments; used as an adhesive component to enhance adhesion; used as a sizing agent and finishing agent in textile printing and dyeing to give fabrics antistatic and soft properties.
FAQ
Q: How is the quality of polivinilpirrolidone products guaranteed?
A: The production follows strict GMP standards, with multiple tests from raw materials entering the factory to finished products leaving the factory, such as accurate determination of impurity content, degree of polymerization, and K value, to ensure that it meets the quality requirements of different levels such as medicine and food.
Q: What is the quality stability of different batches of products?
A: Using automated precision control production equipment and standardized processes, key parameters are monitored and regulated in real time, each batch of products is strictly inspected, and quality fluctuations are controlled within a very small range.
Q: What specifications of products can you provide?
A: It covers industrial grade, pharmaceutical grade, and food grade. There are many models with K values from low to high, such as K12, K30, K90, etc., and special molecular weight and purity specifications can also be customized according to needs.
Q: What are the performance differences of products with different K values?
Answer: The K value is related to the molecular weight. A low K value means good fluidity and low viscosity, which is suitable for systems with low viscosity requirements. A high K value means good film-forming and thickening properties, and is used in scenarios requiring strong adhesion and high viscosity.
