Common functional masterbatches include antibacterial masterbatch, flame retardant masterbatch, antistatic masterbatch, filling masterbatch, cooling masterbatch, anti-formaldehyde masterbatch, anti-ultraviolet masterbatch, far-infrared masterbatch, hydrophilic masterbatch, soft masterbatch Granules, negative oxygen ion masterbatch, etc. Today Jincai will briefly introduce common functional masterbatches.
1. Antibacterial masterbatch
  All kinds of antibacterial agents are evenly dispersed in the matrix resin to make a concentrate, that is, antibacterial masterbatch. After mixing a certain amount of antibacterial masterbatch and corresponding resin particles, according to the processing and molding methods of plastics and fibers, plastic parts, products and antibacterial fibers with antibacterial effects (bactericidal and antibacterial effects) on the surface can be obtained.
2. Flame retardant masterbatch
The products added with flame retardant masterbatches can automatically block the spread of flames when encountering fire, and the burned products will be extinguished and no longer burn, which plays a role of flame retardancy.
Generally, flame retardant masterbatches are specially treated to improve their compatibility with plastic resins, making it less likely to cause problems such as delamination, blooming, and patterns even when the amount of flame retardant masterbatches added to the resin is large.
  By adding flame-retardant masterbatches, general plastics meet or approach the application requirements of engineering plastics, which increases the added value of products and reduces the cost of raw materials.
3. Filler masterbatch
The filler masterbatch is a kind of white micron-sized calcium carbonate masterbatch with pure raw material PE, PP or styrene resin as the carrier. The mesh number of calcium carbonate is determined by the user's use effect. It has good physical properties, dispersibility, and stability, and does not affect processing. The precision of the machine screw.
This kind of masterbatch can be widely used in various plastic products such as PE, PP, PS, ABS, etc., such as: PE plastic bags, injection molding, extrusion molding and other products, especially environmentally friendly plastic products that can be incinerated, so that the cost can be reduced Purpose.
 4. Antistatic masterbatch
The antistatic masterbatch is obtained by high-speed mixing of the carrier and the antistatic system, extrusion molding, and then pelletizing, which is used to reduce the surface resistance of the material. Antistatic masterbatches are mainly used in chemical fiber clothing, plastic products and other fields, which can make the surface resistance value reach 108-10Ω, which has a good antistatic effect.
  This product can be added to plastic or chemical fiber materials to avoid static electricity due to the insulating properties of the polymer itself, so that it can adapt to the packaging requirements of the product and the production of special antistatic products, and has a good effect on the surface dust prevention of the product.
5. Anti-formaldehyde masterbatch
  Antibacterial and anti-formaldehyde masterbatches can effectively degrade formaldehyde, benzene, toluene, xylene, ammonia TVOC and other pollutants, and have high-efficiency and wide-ranging disinfection performance; on cigarettes. Toilet waste, the odor produced by animals has the effect of reducing.
During the reaction process of the anti-formaldehyde masterbatch, the masterbatch itself will not change and lose, and it can continuously purify the air under the action of light. It has the advantages of long-lasting and continuous effect. Anti-formaldehyde masterbatch is non-toxic, harmless, safe and reliable to human body. The final reactants are carbon dioxide and water, which will not produce secondary pollution.
6. Cooling Masterbatch
The cooling masterbatch was initially used in the PP spinning process, in order to reduce the high viscosity of PP and prevent the decomposition of other additives and pigments at high processing temperatures. The cooling masterbatch can reduce the molecular weight of PP, thereby reducing the processing temperature of PP.
Its main ingredient is peroxide. At present, the application range of cooling masterbatch has been expanded, and it has become a common additive for some PP modification manufacturers, especially in the production of high-flow PP (such as large thin-walled storage barrels in supermarkets).
  The cooling masterbatch is also mainly used for polypropylene spinning. Due to the high molecular weight of polypropylene, the temperature during spinning is as high as 300°C. In this way, it is easy to decompose additives, pigments, etc. The cooling masterbatch can generally reduce the spinning temperature by 10~50°C, which improves the spinning process.
Foshan Laicai Pigment Masterbatch Technology Co., Ltd. has been focusing on color masterbatch, color masterbatch, black masterbatch, plastic masterbatch production and research and development for 17 years, providing white masterbatch, color masterbatch, black masterbatch , Plastic masterbatch production.
