Functional Cellulosic Polymers
Cellulose backbone allows modifications while in the production process or when in the final product form. To make the Cellulose Derivatives selectively functional, TPI Chemicals have developed a unique modification process in which different Cellulosic polymers can be modified as required. Viscosity, product granulometry, chain structure a few properties to name for making Cellulosic Polymers Functional for the applications they are used.
Carboxymethyl Cellulose (CMC)
Polyanionic Cellulose (PAC)
Similar to the CMC in chemical properties, the Polyanionic Cellulose is the grade used in oil, gas and water drilling fluids. Primarily available in Low and High Viscosities, fluid loss control and viscosity building are the basic functions of this polymer which plays a quite important role in a trouble free operation of the drilling well. API 13A is the industry standard of the Polyanionic Cellullose which sets the min and max specifications that the product should have.
Microfibrilated Cellulose (MFC)
Being purely a natural bio-polymer, MFC is a relatively new but a multi functional product that is manufactured through getting into the micro scale fibrils that form the cellulose fibers. Increased surface area by seperating the fibrils through different processes make the MFC a versatile product for different applications. High water retention capacity, heat and pH stable gel formation, shear thinning are few properties of many that come with the MFC.
MCC
Microcrystalline Cellulose (MCC) is a water insoluble crystalline cellulose powder, used in different application areas as suspension aid, emulsion stabilizing agent, anti-caking aid and tableting agent.
HPMC
Hydroxypropyl methylcellulose is a nonionic thermo-reversible gel forming cellulose ether. It is used as water retention, thickening and film-forming agents, protective colloids, suspending and emulsifying agents, binder and stabilizer.
Modified Starches
Starch Derivatives are manufactured by physical or chemical modification from native starches in order to make this polysachharide cold water soluble thus have improved features such as film forming, adhesive, thickening, stabiling.
Cellulose Pulp
Bleached Wood and Cotton Linters Pulp, available in different specifications, primarily intended for Cellulose Ethers production, is one of the product lines of TPI Chemicals.
