Description:

Copolymer Beads formula is designed to give the most efficient mechanical lubrication for all drilling fluids especially Horizontal Directional Drilling (HDD) or coil tubing solutions. Copolymer Beads reduce coefficient of friction, more energy to bit, lower torque and drag, increase penetration rate, extent bit and motor life, decrease wear and tear on drill pipe, and major cost savings for customers.

• Divinylbenzene (DVB)

Divinylbenzene (DVB) is a clear yellow liquid with an aromatic odor. DVB is used as a cross-linking agent, meaning it is used to join together individual chains within a polymer. DVB is a mixture of isomers of divinylbenzene and ethylvinylbenzene (EVB, CAS No. 28106-30-1). Jiangsu Andeli manufactures DVB products contain 52-83% of the active cross-linker, respectively.

Product Uses
DVB is a chemical intermediate used to modify the properties of a wide variety of materials. The primary use for DVB is in the production of cross-linked polystyrene resin beads. These styrene DVB copolymer beads are chemically modified to produce ion exchange resins.
Typical applications for DVB:
• Adhesives – improves high-temperature strength of adhesives used to bond aluminum to aluminum, added to caulks and mastics for the

                        construction industry
• Biological – improves physical properties of cell culture micro-carrier beads, incorporated into a hydrogel for slow nutrient release fertilizer
• Catalysis – used in hydrophobic foam catalyst, serves as a catalyst for hydrolyzing nitriles to amides
• Ceramics – improves physical and mechanical properties of fired clay bodies
• Chromatography – used in resins for reversed-phase liquid chromatography and ion exchange chromatography packings
• Coatings – improves surface properties of rubber goods for biomedical applications, used in photocurable protective coatings for wood, metal, glass, and plastic
• Combinatorial chemistry – used to create functionalized copolymers that are useful drug screening tools
• Composite plastics – allows higher production rates, enhanced physical properties, exceptional smoothness
• Elastomers – increases skid-resistance of some rubber compounds, improves adhesion of rubber to steel
• Electrochemical – increases electron sensitivity in electron-beam lithography, improves storage stability of alkaline batteries, improves properties of  electrostatic image toners
• Ion Exchange – used in the production of resin beads that reduce bead swelling, increase bead strength, improve water retention and capacity
• Membranes – used in polymers for electrolysis-diaphragm and piezodialytic-transport membranes
• Optical – used in polymers for ophthalmic and photochromic lenses
• Pharmaceutical – used in polymers for enzyme and coenzyme mobilization, dental cement,and prosthesis materials
• Polymer synthesis – used in polymers for waterproof fabric manufacture, enhanced radiation grafting of polymers, living polymer-polyvinyl aromatic compound coupler
• Plastics – used extensively as a cross-linker and to aid in copolymerization
• Reprography – used to make copy machine toner resins
• Rubber – used as a processing aid in the extrusion of general-purpose synthetic rubbers
• Star polymers – used in polymers used as motor-oil viscosity modifiers
