(2) Thermal Conductive Graphene Series
1, Model: TECG-1, TECG-2, TECG-3
2, Performance and uses
Lower percolation threshold and more stable conductivity than conductive carbon black, low dosage and high efficiency. The sheet is thin, easy to disperse and easy to process. In the conductive (static) electric paint, it is recommended to add about 1~3%, which can make the coating have excellent conductivity (static) performance, good mechanical properties and anti-corrosion performance; suitable for positive and negative materials of lithium ion batteries. Coating can effectively improve battery energy and improve cycle life and rate performance. Excellent thermal conductivity, can prepare thermal conductive composite materials, heat-dissipating coatings, etc. Mainly used in coatings, inks, plastics, rubber, lithium-ion batteries, thermal adhesives, LED heat dissipation and other fields.

Flame retardant graphene series
This product is a graphene-enhanced halogen-free, green and environmentally friendly flame retardant. The product is insoluble in water and organic solvents and is not easily soluble in strong acid and alkali solutions. It has high efficiency flame retardant, high thermal stability, non-toxicity, low smoke, small particle size, small specific gravity and good dispersibility. It can be widely used as a high-efficiency flame retardant for thermoplastics (such as PA, PBT), fiber and textiles. Flame retardant and so on. At the same time, it can be directly added to the polymerization system without affecting the polymerization process. Phosphorus content /% (w / w): 15 ~ 22%, moisture or low volatiles /% (w / w): <0.5; bulk density / kg / m3: 200-350. decomposition temperature (°C): > 300 .Particle division D50 (um): 10-20
