Dispersed PTFE is a secondary particle formed by the coagulation of PTFE dispersed particles, with a diameter of 500μm. It is in powder form and has a large specific surface area. After absorbing organic solvents, it forms a paste under the action of shear force. It is usually formed by extrusion molding process, so it is called paste extrusion molding. 1.PTFE dispersion impregnation. Products made by impregnating asbestos, glass fiber, glass cloth, porous metals and other materials with PTFE dispersion have excellent properties, such as non-absorbency of water, good non-stickiness, lubricity and air tightness, as well as excellent chemical corrosion resistance at high temperatures. 2.Coating and molding of PTFE dispersion. PTFE dispersion forms coatings on the surfaces of metals, ceramics, wood and plastics, endowing these material surfaces with anti-sticking, low friction coefficient and moisture-proof properties, thus greatly expanding the application range of these materials. The coating processes include electrostatic spraying, plasma spraying, etc. 3.Wet mixing and filling of PTFE. Wet mixing is the process of uniformly mixing PTFE dispersion and filler to make them co-coagulate. The PTFE products prepared by this method have relatively high mechanical strength, good wear resistance and dielectric properties. However, due to the poor thermal stability of emulsion polymerization resin, they are only limited to manufacturing thin-walled and small-sized products. 4.PTFE dispersion casting molding. PTFE dispersion film casting is a process where PTFE dispersion is continuously applied to a highly polished metal strip in continuous operation. The coated PTFE is then sent to a high-temperature tower for baking. After all the moisture and surfactants have completely evaporated, the product is sintered at 360-380℃. The products processed by this method are called PTFE film casting. The surface is smooth and soft, and it is used as insulation for capacitors For more details, please click below to enter the official website:

Acrylic emulsion polymers are widely used in coating printing, electrostatic flocking, fabric lamination, warp sizing and coating processing, etc. Different types of acrylate with various properties also have their own different applications due to the differences in raw materials and ratios used. Common characteristics of oleic acid emulsion Outstanding adhesion: The polymer structure of waterborne acrylic emulsion facilitates the flow and wettability of molecular chains on the substrate surface, enabling close contact between the coating and substrate molecules and achieving high adhesion. The high load-bearing capacity of pigments and fillers can significantly reduce costs: Waterborne acrylic emulsion has excellent filling properties, and the total solid content of the coating formula can reach 60%. Significantly reduce the formulation and application costs of water-based wood coatings. Zero-voc safe and environmentally friendly: Water-based acrylic emulsion itself contains no VOC and can form a film at room temperature without the need for film-forming AIDS. The VOC content of the coating with such a formula can be zero. Excellent water resistance: Water-based acrylic emulsion does not contain the surfactants used in ordinary acrylic emulsion and has specially designed hydrophobic groups. It can prevent water molecules from penetrating the substrate after the paint film dries, achieving the effect of waterproofing and moisture-proofing. Excellent weather resistance: The molecular structure of water-based acrylic emulsion all adopts UV-stabilized monomer structure. Moreover, the emulsion is specially designed to ensure that TIO2 is fully and uniformly dispersed in the emulsion, reducing the influence of ultraviolet rays on the emulsion and effectively protecting the substrate. Excellent pigment dispersion: The water-based acrylic emulsion has good compatibility with various water-based color pastes, which maximizes the functions of fillers and pigments, resulting in bright and vivid coating colors.

The parameters of textile coating emulsion include appearance, viscosity, solid content, pH value, glass transition temperature (Tg), storage temperature and shelf life, etc. These parameters are crucial for evaluating the performance and application conditions of the emulsion. The following are some specific parameter descriptions: Appearance: The emulsion can be a milky white slightly blue phase liquid or a light yellow liquid, depending on the specific type and composition of the emulsion. Viscosity: Viscosity is an indicator for measuring the fluidity of emulsions. Different types of emulsions have different viscosity ranges. For example, the viscosity of the textile emulsion PA-510 is less than 500 mPa·s, while the viscosity range of the vinyl acetate-ethylene copolymer emulsion is between 1000 and 1500 mPa·s. Solid content: Solid content refers to the proportion of solid components in an emulsion, expressed as a percentage. For example, the solid content of the textile emulsion PA-510 is 45±1%. pH value: The pH value reflects the acidic or alkaline properties of the emulsion. Different emulsions have different pH value ranges. For instance, the pH value of high-elasticity waterborne acrylic emulsion is between 7 and 8, while that of silicone emulsion is between 6 and 8. Glass transition temperature (Tg) : The glass transition temperature is the temperature at which a material transitions from the glassy state to the rubbery state. Different emulsions have different glass transition temperatures. For example, the glass transition temperature of the textile emulsion PA-510 is -16℃. Storage temperature: Emulsions should be stored within a specific temperature range to maintain their performance. For instance, the storage temperature for highly elastic waterborne acrylic emulsions is 5 to 40 degrees Celsius. Shelf life: The shelf life of an emulsion refers to the length of time it can maintain its performance under specific conditions. For instance, the shelf life of a highly elastic water-based acrylic emulsion is 9 months. These parameters jointly determine the application performance and usage conditions of the emulsion, which is crucial for choosing an emulsion suitable for a specific purpose Sinograce Chemical produces waterborne acrylic emulsion and waterborne polyurethane for use in the textile industry.
