Product Name: Hydroxypropyl methyl cellulose/Hypromellose Other Name: hpmc powder Molecular Formula: C3H7O Molecular Weight: 59.08708 Appearance: White Powder Purity: 99% CAS NO.: 9004-65-3 EINECS No.: 618-389-6 Supplier: ZHENYIBIO Hydroxypropyl Methyl Cellulose (HPMC) are water soluble polymers derived from cellulose. They are typically used as thickeners, binders, film formers, and water retention agents. They also function as suspension aids, surfactants, lubricants, protective colloids, and emulsifiers. In addition, solutions of these polymers thermally gel.

Commodity:Sodium persulfate Molecular Formula : Na2S2O8 Molecular weight : 238.13 Description Sodium persulfate is a white,crystalline,odourless salt.It is used as initiator for the Polymerization of monomers and as a strong oxidizing agent in many applications.It has the particular advantage of being almost non - hygroscopic,of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

Storage NPS(SPS) is not combustible but assists combustion materials due to release of oxygen.Provided it is stored under appropriate condition.It must be stored dry in closed containers and protected from direct sunlight,heat and humidity.Impurities such as dirt,rust or traces of metal and reductants may cause catalytic decomposition.The product as supplied or in solution needs to be handled with appropriate care.The eye,skin and clothes must be protected when working with NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect. Application Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc. Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors; cleaning and etching of printed circuits),activation of copper and aluminium surfaces. Cosmetics : Essential component of bleaching formulations. Paper : modification of starch,repulping of wet - strength paper. Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans). Others : - Chemical synthesis - Water treatment(decontamination) - Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg) - Disinfectant ITEMS SPECIFICATIONS Appearance white crystalline salt Assay 99.0% w/w min Active oxygen 6.65% w/w min Chloride and chlorate(as CL) 0.005% w/w max Ammonia (NH4) 0.05% w/w max Manganese(Mn) 0.0001% w/w max Iron(Fe) 0.001% w/w max Heavy metals(as Pb) 0.001% w/w max Moisture 0.05% w/w max Decomposition of the product as supplied at above 65C Recommended storage temperature Normal Temperature Storage stability as from date of delivery 12 months
