Polyvinylpyrrolidone, additionally recognised as PVP, is a polymer of ethylene pyrrolidone. Due to its one-of-a-kind ranges of polymerization, it can be divided into soluble PVP and insoluble PVPP (polyvinylpyrrolidone). The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate with the aid of reacting with polyphenols. By the use of this method, there are without problems residual PVP in the wine.

The conductivity of carbon black is carefully associated to its shape (especially graphite microcrystalline structure), floor properties, and particle size. The conductive mechanism of carbon black in rubber often consists of conductive channel and Field electron emission mechanism. The conductive channel mechanism is that carbon black aggregates come into contact with every different in the adhesive to structure a community like channel and behavior electricity.

Harmony Chemical Ltd. attended ICIF China 2019 held from September 16 to 18, 2019 in Shanghai, China. The exhibition cover a series of activities based on trade talks, technical exchanges, economic cooperation, information dissemination and special conferences.
Shandong Province  is known for its mild coastal monsoon climate, which makes it ideal for large-scale trials of biodegradable mulch. As a call for green agriculture, Harmony Chemical has developed 100% biodegradable agricultural mulch materials and worked with a downstream company and research institute to achieve their commercialization.
From September 6th to 8th, Harmony Chemical Ltd. were invited to exhibit at the Coatings Trends and Technology Summit (CTT).  The coatings industry is no exception in a world increasingly conscious of carbon footprints. The theme at the CTT revolved around green technology, and many companies are eagerly seeking sustainable solutions. Harmony Chemical Ltd.
Recently, the Center for the Polyurethanes Industry (CPI) announced Harmony Chemical as the finalists for this year’s Polyurethane Innovation Award. The annual honor recognizes inventive new commercial technologies within the polyurethanes industry. The award will be presented to the winner during the 65th Polyurethanes Technical Conference, September 25-27, in San Antonio, TX.    Harmony Chemical Resin is a specially designed binder based on polymeric methylene diphenylene diisocyanate (pMDI).
