Performance characteristics
Good compatibility: It has good compatibility with a variety of polymers, can be evenly dispersed in the polymer matrix, and is not easy to phase separate, thus giving the product good physical and mechanical properties.
Low volatility: It has low volatility, is not easy to volatilize and lose during processing and use, can be kept in the product for a long time, and effectively extends the service life of the product.
Good migration resistance: When in contact with other materials, it is not easy to migrate, and will not have adverse effects on the materials in contact with it, ensuring the quality stability of the product.
Excellent cold resistance: It can still maintain good flexibility and elasticity in low temperature environments, so that the product is not easy to crack under cold conditions, and has good cold resistance.
Strong thermal stability: It has good thermal stability at higher temperatures, can withstand a certain processing temperature, is not easy to decompose or deteriorate, and ensures the smooth progress of the processing process.
Low toxicity: It has relatively low toxicity to the human body and the environment, meets relevant safety standards, and is safer to use.
Application areas
Plastic processing: widely used in the processing of plastics such as polyvinyl chloride (PVC), polyurethane (PU), polystyrene (PS), etc. As a plasticizer, it can significantly improve the flexibility, ductility and processing performance of plastics, reduce its hardness and brittleness, and make plastic products have better performance.
Rubber industry: In rubber products such as tires, conveyor belts, seals, etc., DPGDB can be used as a softener and plasticizer to improve the flexibility, elasticity and wear resistance of rubber, and improve the quality and service life of rubber products.
Coatings and inks: As an additive for coatings and inks, DPGDB helps to improve the fluidity, drying speed and gloss of coatings and inks, so that the coating has better adhesion and water resistance, and can also improve the printing performance of inks.
Adhesives: Adding DPGDB to adhesives can enhance the viscosity and flexibility of adhesives, improve the bonding strength of adhesives to different materials, and make them suitable for bonding a variety of materials.
Cosmetics: In cosmetics, DPGDB can be used as a solvent and plasticizer. It has good solubility and compatibility, and can make the ingredients in cosmetics evenly mixed, improving the stability and feel of cosmetics.
Application method
Direct addition: In the production process of plastics, rubber, coatings and other materials, DPGDB is directly added to the raw materials in a certain proportion, and it is evenly dispersed in the base material through stirring, mixing and other processes, and then the subsequent processing and molding operations are carried out.
Premixing: For some applications that require high mixing uniformity, DPGDB can be premixed with part of the base material to make a masterbatch or premix, and then the masterbatch or premix is mixed with the remaining base material for processing, so as to ensure that DPGDB is more evenly distributed in the material.
Used in conjunction with other additives: DPGDB is often used in conjunction with other additives such as antioxidants, UV absorbers, lubricants, etc. to exert better comprehensive performance. When using it, it is necessary to reasonably select the type and amount of additives to be matched according to the specific application requirements and material formula.
