II. Product introduction:

 

YY-502A is a high-performance plastic additive with a variety of functions in one. It adopts special chemical synthesis technology and functional composite technology to graft organic functional groups with the ability of clapping onto high polymers. Therefore, the product integrates various functions such as dispersant, compatilizer, and processing aid in one.

 

Three, application scope:

 

1. It is suitable for the plastic modification of all kinds of high fillers. It has the functions of dispersing the fillers and improving the processing fluidity, so as to improve the appearance of the products without affecting the mechanical properties.

 

2. Used in all kinds of high temperature masterbatch and functional masterbatch of high fillers, it has better dispersing and coupling activation treatment effect on inorganic fillers, and obviously improves the product appearance and overall performance.

 

3. Used for surface activation modification of inorganic fillers, such as calcium carbonate, talcum powder, mica powder, wollastonite, old soil, magnesium hydroxide and aluminum hydroxide surface treatment, the product can directly react with the fillers, and has a better coating effect.

 

4. It can be directly added to injection molding products to improve fluidity and product appearance and reduce product defect rate.

 

Four, application effect:

 

1. The inorganic filler has a strong affinity, so that it is fully activated and modified, destroy and prevent the agglomeration of inorganic substances, so as to more evenly dispersed into the polymer, thus can increase the amount of filler, and rely on strong interface key cooperation, to achieve the effect of reinforcing toughness.

 

2. In the processing of polymer composites, it can improve the compatibility of each component of the system, promote plasticization, reduce melt viscosity, improve processing fluidity, reduce the button moment of processing equipment, reduce processing energy consumption, and improve production efficiency. It can improve the mechanical properties of the products such as impact strength and elongation at break, and improve the surface luster of the products.

 

3. Because this product is highly reactive multifunctional structure of anchor groups, through multipoint adsorption of the groups "anchor", at the same time for chemical reaction was carried out on the filler particle surface modification, surface chemical reaction of perfection, the organic filler surface, which can effectively reduce the surface of the packing, in addition, the product of macromolecular polymer long chain of matrix polymer material with a very strong affinity and compatibility, the composite material system processing performance is greatly improved, and the physical properties are not affected.

 

Five, use method:

 

1. Add the filler into a high-speed mixer, then add YY-502A high activity coupling modifier at 2-3% of the weight of the filler, and mix evenly.

 

2. There are good successful cases in the application of conductive masterbatch. The addition of about 1%YY502A can significantly improve the conductivity and dispersion, and has been selected by many large domestic conductive masterbatch manufacturers. .

 

3. This product is granular or powder, melting point at about 120℃, easy to use, suitable for continuous production.

 

VI. Packaging and Precautions:

 

1. Lined with compound bag, 20Kg/ bag

 

2. Prevent extrusion, seal away from light and moisture.
