Products
Lithium batteries and materials
Lithium-ion batteries and other traditional types of batteries, such as the common alkaline battery. Nickel-metal hydride batteries, etc., have the same work, but the advantages of lithium ion batteries, one is that its manufacture and use almost no pollution and damage to the environment, two is that it can be stored and use time is hundreds of times more than the traditional battery.

From chemical system used in lithium batteries, lithium ion batteries commonly used ordinary lithium salt as the anode, such as cobalt acid lithium iron phosphate lithium manganese acid lithium nickel manganese cobalt acid lithium and so on, the use of chemical elements in the periodic table 4 main group elements of simple substance or compound, as the cathode, charge and discharge, through the lithium ion in anode materials are shuttling between the formation of storage charge.

Ternary Cathode Material is the key materails used in the production of rechargeable lithium batteries, costing more tha 40% of the cell budget. Our company's main business products are ternary materials, aiming to provide customers with the best cathode material solutions. Our materials are widely used in portable electronic products, electric tools, and new energy vehicle to reduce carbon dioxide emissions.

Fluorine series
Our Fluorine business includes inorganic fluoride，fluorine polymers and fluorine-containing fine chemicals. Major products consist of R134a、R125、PTFE, PVDF, fluorine rubber, tetrofluoropropanol,:lithium hexafluorophosphate， etc. The products are comprehensively applied in the fields of electronical communication, aerospace, petrochemical, automobile, textile, medicine, etc. The subsidiary company in this business is Zhonghao Chenguang Research Institute of Chemical Industry Co. Ltd. The typical applications of fluorine products are:

1、 Refrigeration/Air conditioning:As the refrigeration working media, refrigerating fluid plays a role in thermodynamic cycle of vaporization heat absorption and condensation heat release in the refrigeration system so as to realize the purpose of refrigeration. Sinochem Lantian has different kinds of refrigerating fluids of different series, all of which have been applied to such industries as auto and home appliances and also start to apply to heat pump industry and cold chain logistics gradually.

2、Lithium battery：Electrolyte, as one of the four key raw materials of lithium ion battery, plays a role in ionic conduction between the battery anode and cathode and therefore can be applied to many lithium battery downstream industries such as power vehicles, energy storage, 3C digital, electric tools and electric bicycle. Sinochem Lantian has cultivated a high quality electrolyte R & D team which can satisfy customer’s requirements for high energy and density, safety, low cost, high and low temperature, etc.

3、Applications of PTFE resins: 1. Applied to the fields of electronics, communications and automobiles for making catheters and cables; 2. Making valves, pipelines, elbow linings, diaphragms, etc. 3. Making water-based paints for non-stick pan.

Engineering plastics
Engineering plastics are a type of high-performance polymer materials that can be used as structural materials, withstand mechanical stress in a wide temperature range, and used in more demanding chemical and physical environments. The performance characteristics of engineering plastics can withstand a certain external force, have good mechanical properties and dimensional stability, can still maintain its excellent performance at high and low temperatures, and can be used as engineering structural parts.

The main properties of engineering plastics are the thermal properties of glass transition temperature and melting point, high heat distortion temperature, high temperature for long-term use, large temperature range, and small thermal expansion coefficient. Mechanical properties include high strength, high mechanical modulus, low creep, strong wear resistance and fatigue resistance. Other properties include chemical resistance, electrical resistance, flame resistance, weather resistance, and good dimensional stability.

The main products of the company is PPE、PC、PA、PBT、ABS and epoxy resins.

Polymer additive
Polymer additives are special chemicals used in the polymerizing and processing of polymer materials to improve the properties of polymers. such as anti-oxidation and flame-retardant properties. They can also be used to improve polymer processing properties, such as plasticization and lubrication.

Since 1990s, the invention of new polymers has been declining, whereas the market demands for the application and processing properties of polymers has been growing strongly.When it comes to meeting the customization requirement, people can only use highly specific polymer additives to help realize or enhance corresponding properties. The applications of polymer additives products include:

1、Antioxidants can significantly improve the aging indicators of rubber chemicals. When applied in tires, antioxidants can not only slow down the aging of tires, but also extend their service life and increase their safety.Sennics regards antioxidants as an important part of its "green and customized formula solution", to meet customers' higher expectations.

2、Insoluble sulfur is produced through the thermal polymerization of ordinary sulfur. It connects linear rubber polymers into dense nets, to physically increase the density of the overall structure.Insoluble sulfur enables the adhesion between plies and rubber to be stronger.Insoluble sulfur is the cores of Sennics multi-product strategy, and an important basis for creating the green and circular industry chain.

3、Accelerators：In the process,the sulfur vulcanization time can be significantly reduced, the density of cross-linking can be increased. In the development of accelerants, a high quality and a circular economy, Sennics has eliminated the production of saline wastewater, and has realized a circular loop between upstream and downstream operations.
