Polyvinylpyrrolidone (PVP), also known as polyvinylpyrrolidone, is a water-soluble polymer compound formed by the polymerization of N-vinylpyrrolidone monomers. It appears as a white powder.
Core characteristics: strong water solubility, can be quickly dissolved in cold water; good chemical stability, adapt to pH 3-11 environment; divided into K value series according to different polymerization degrees, corresponding to different viscosities and functions.
Preparation process: mainly produced by solution polymerization or suspension polymerization process, strictly controlling reaction parameters to ensure that product quality meets the pharmacopoeias and industry standards of various countries.
Application fields: widely used in medicine (adhesives, solubilizers), cosmetics (thickening, film formation), food (beverage clarification), coatings and inks (improved dispersibility) and water treatment (auxiliary flocculation) and other fields.
Quality assurance: production follows the ISO quality management system, the finished product undergoes multiple tests, and provides detailed quality inspection reports to ensure batch stability and safety.
FAQ
Q: How is the quality stability of Polyvinylpyrrolidone (PVP)?
A: We use a fully automated polymerization production line and strictly implement the ISO 9001 quality management system. From the purchase of raw material N-vinylpyrrolidone to the delivery of finished products, we go through 12 quality inspection processes. Each batch of products provides a test report that meets the pharmacopoeia standards such as USP, EP, and ChP to ensure that the K value deviation is ≤±0.5 and the impurity content is 30% lower than the industry average.
Q: Compared with other suppliers, where is the price advantage?
A: Relying on the advantages of large-scale production (annual production capacity exceeds 5,000 tons) and self-developed polymerization technology, we have achieved a 25% reduction in energy consumption and an increase in raw material utilization rate to 98%. Directly connecting with raw material manufacturers to reduce intermediate links, the price of conventional models is 15%-20% lower than the market price, and bulk purchases can enjoy a step discount.
Q: What is the delivery cycle and minimum order quantity?
A: Standard models (such as K15, K30, K90) are in sufficient stock and can be shipped within 48 hours; customized products (special K value or modification requirements) can be delivered in as fast as 7 working days. The minimum order quantity is only 100 kg, mixed batch purchases are supported, and new customers will receive an additional 10% trial pack for their first order.
Q: What is the technical support for the product in different application scenarios?
A: Equipped with a technical team led by 5 doctors, we provide customized solutions for the pharmaceutical, cosmetics, food and other industries. For example, the pharmaceutical field can assist in optimizing the formulation of sustained-release preparations, and the cosmetics industry can provide film-forming performance improvement solutions. We respond to technical consultations within 24 hours and provide on-site debugging services when necessary.
Q: What are the requirements for packaging and storage?
A: Double-layer packaging is used, with the inner layer being a food-grade PE moisture-proof bag and the outer layer being a 50 kg cardboard barrel. 25 kg carton packaging can be customized for special needs. The storage conditions are a cool and dry environment (temperature ≤ 30°C, humidity ≤ 65%), the shelf life is 3 years, and the product label must be clearly marked with the MSDS safety data sheet.
