PE-Wax (Polyethylene Wax) is a synthetic wax that is produced by polymerizing ethylene in the presence of a catalyst. PE-Wax raw materials are characterized by their low molecular weight, low melting point, and excellent compatibility with other polymers and additives.

PE-Wax raw materials are preferred over other waxes due to their excellent dispersibility, low viscosity, and low cost. They are available in various grades, depending on the desired melting point, hardness, and molecular weight distribution. The selection of the appropriate PE-Wax raw material depends on the specific application requirements, such as the desired lubrication properties, thermal stability, and regulatory compliance. It is essential to choose the right PE-Wax raw material and follow the recommended safety and regulatory guidelines to ensure the best performance and safety of the final product.

Flame retardant raw materials are chemical additives that are used to reduce the flammability of materials and prevent fires from spreading. They are commonly used in plastics, textiles, and other materials that are prone to catching fire. Flame retardants work by interrupting the combustion process, either by forming a protective barrier that prevents oxygen from reaching the fuel, or by releasing water or gases that dilute the flammable vapors. 

There are several types of flame retardant raw materials, including halogenated compounds, phosphorus compounds, nitrogen compounds, and inorganic compounds. Halogenated flame retardants are the most common and include chemicals such as brominated and chlorinated compounds. Phosphorus flame retardants work by forming a char layer on the surface of the material that acts as a barrier against heat and flames. Nitrogen flame retardants release gases that dilute the flammable vapors and prevent combustion. Inorganic flame retardants, such as aluminum hydroxide and magnesium hydroxide, act as physical barriers that absorb heat and release water vapor.

Antioxidant raw materials are chemical additives that are used to prevent oxidation and degradation of materials, such as plastics, rubber, and coatings, caused by exposure to heat, light, or oxygen. Antioxidants work by scavenging free radicals and reactive oxygen species, which can cause chain reactions that lead to the breakdown of the material.

There are several types of antioxidant raw materials, including primary antioxidants, secondary antioxidants, and synergists. Primary antioxidants, such as phenolic compounds and amines, act by donating hydrogen atoms to the free radicals and forming stable products. Secondary antioxidants, such as phosphites and thioesters, work by decomposing peroxides and other reactive species before they can initiate the chain reaction. Synergists, such as metal deactivators and UV stabilizers, enhance the effectiveness of the primary and secondary antioxidants by preventing the formation of free radicals and absorbing UV radiation.

UV and HALS raw materials are chemical additives that are used to protect materials, such as plastics, coatings, and textiles, from the harmful effects of UV radiation and other environmental factors, such as heat and humidity. These raw materials are commonly used in outdoor applications where prolonged exposure to sunlight and other weather conditions can cause degradation and discoloration of the materials.

UV raw materials work by absorbing or scattering UV radiation, which can cause photodegradation and fading of colors. They are typically organic compounds, such as benzotriazoles, benzophenones, and hindered amine light stabilizers (HALS), which are incorporated into the material to be protected. HALS are a type of antioxidant that works by scavenging free radicals and reactive oxygen species that are generated by UV radiation and other environmental stressors.

Calcined alumina is a high-temperature processed raw material that is produced by heating aluminum hydroxide at a temperature of approximately 1200 °C. The resulting material is a white crystalline powder with a high degree of purity and a uniform particle size distribution.

Calcined alumina is widely used in various industrial applications, such as ceramics, refractories, abrasives, and catalysts, due to its excellent physical and chemical properties. It has a high melting point, high hardness, good thermal and electrical conductivity, and excellent chemical stability. These properties make it an ideal material for use in high-temperature environments, abrasive products, and catalyst supports.

In the ceramic industry, calcined alumina is used as a raw material for the production of high-performance ceramic parts, such as cutting tools, electronic components, and wear-resistant parts. In the refractory industry, it is used as a raw material for the production of high-quality refractory bricks, which are used in high-temperature applications, such as furnaces and kilns. In the abrasives industry, it is used as a raw material for the production of grinding wheels, sandpapers, and polishing compounds. In the catalyst industry, it is used as a support material for the production of heterogeneous catalysts, which are used in various chemical processes.

Biodegradable raw materials are materials that can be broken down into natural substances by microorganisms, such as bacteria or fungi, in the environment. These materials are designed to reduce the impact of waste on the environment and promote sustainability.

Some examples of biodegradable raw materials include bioplastics, bio-based polymers, and natural fibers. Bioplastics are plastics made from renewable resources, such as starch, cellulose, and vegetable oil, and are designed to biodegrade under certain conditions. Bio-based polymers are polymers made from renewable resources, such as corn, sugarcane, or potato starch, and are also biodegradable under certain conditions. Natural fibers, such as jute, hemp, and cotton, are also biodegradable and can be used as an alternative to synthetic materials.

Biodegradable raw materials are used in a wide range of applications, such as packaging, textiles, agriculture, and healthcare. In the packaging industry, biodegradable materials are used to produce packaging products, such as bags, containers, and wrapping, which can be composted or recycled after use. In the textile industry, biodegradable fibers are used to produce clothing, accessories, and home furnishings, which can be composted or recycled after use. In the agriculture industry, biodegradable materials are used to produce biodegradable mulch films, which can reduce soil pollution and improve soil quality. In the healthcare industry, biodegradable materials are used to produce medical implants, such as sutures and bone plates, which can be absorbed by the body and do not require surgical removal.

The use of biodegradable raw materials can help to reduce waste and promote sustainability, but it is important to ensure that these materials are properly disposed of and recycled to avoid environmental pollution.
