Hydroxypropyl Methyl Cellulose products have the maximum consumption in the area of suspension polymerization of vinyl chloride in China. In the suspension polymerization of vinyl chloride, the dispersed system has a direct impact on the product, PVC resin, and on the quality of its processing and products. Hydroxypropyl Methyl Cellulose helps to improve the thermal stability of resin and control the particle size distribution(in other words, adjust PVC density), and its amount accounts for 0.025% -0.03% of PVC production.

Main applicationHPMC is one of the main dispersants in PVC industry. During suspension polymerization of vinyl chloride, it can reduce the interfacial tension between vinyl chloride monomer (VCM) and water, and help VCM to be evenly and stably dispersed in the aqueous medium; Prevent the coalescence of VCM droplets at the initial stage of polymerization; Prevent coalescence between polymer particles in the later stage of the polymerization process. In suspension polymerization system, it plays a dual role of dispersion and stability protection.

Hydroxypropyl Methyl Cellulose (Mellutel YT-50) is beside Polyvinylalcohol (PVA) one of the most commonly used suspending agents. Mellutel YT-50 controls the particle size and their distribution, influences the porosity and defines the bulk weight of PVC. The porosity of the polymer particles is strongly linked to the property to adsorb additives like plasticizers or stabilizers. Thereby, the properties of the polymer during processing and of the final product can be controlled. Ultra low viscous Mellutel YT-50 is the most suitable product for PVC manufacturing processes.

This product is industrial HPMC, which is mainly used as dispersant in PVC production, and is the main auxiliary agent for preparing PVC by suspension polymerization. In addition, it is used as thickener, stabilizer, emulsifier, excipient, water-retaining agent, film-forming agent, etc. in the production of other petrochemical, paint, building materials, paint remover, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, paper making, cosmetics and other products.

Cellulose ether has a wide range of uses in the building materials industry.Can be used as retarder, water retention agent, thickener and binder.The most important roles of cellulose ether (especially HPMC and HEMC) in cement-based adhesives are water retention and thickening.In addition, due to its interaction with the cement system, it also plays an auxiliary role in entraining air, delayed coagulation and improving tensile bond strength.Structural formula (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]nOH or-[OCH2CH(CH3)]OCH3 Specification of non modified products
