n: an unwanted substance produced because of some reaction such as cracking, dehydrogenation, or polymerization. The term implies the formation of a contaminant or low-value product.

an organic resin, formed by polymerization reaction of furfuryl, used in consolidation, zone shut-off and water control.

n: the CMC product with high degree of polymerization ,high molecular weight and viscosity ,mainly used as adhesion promoter

n: CMC strain that made of short fibre, it has low viscous and degree of polymerization(D.P).

n: CMC strains that its degree of polymerization is medium, and made of wood pulp.

n pi: units in a refinery that polymerize propylene and ethylene in the presence of a catalyst and in a liquid solvent. Polypropylene and polyethylene are produced. Following polymerization, the product is removed from the reactor and processed through a purification facility for removal of catalyst residue and separation of the sol vent. The powdered product is then conveyed in a pneumatic conveyor to the finishing area, where additives are blended with powder and the mixture is processed through an extruder to form pellets.

n: the bonding of two or rnore sirnple rnolecules to form larger molecular units.
