ACR Processing Modifier

a,

a new PVC processing aid is a modified acrylic polymer combined with a combination of inorganic nano-materials, developed a new type of modified PVC processing aid, it takes full advantage of nano-materials, surface area, surface free energy big features, to overcome the traditional PVC processing aids in plasticizing properties when the temperature decreases worse defects. In the process, the nano-materials a strong surface tension, into the internal friction with the PVC molecules, because the internal friction increases with decreasing temperature, which improves the performance of traditional plastics ACR, with the temperature drop the problem significantly worse. Compared with the traditional ACR has the following characteristics:

1, static stability is better than the conventional processing aids.

2, temperature changes, corresponding changes in shear stress can make essentially the same degree of PVC plastics.

3, can greatly improve the processing properties of PVC to improve the surface finish of products.

4, weathering

weather resistance of plastics in two ways, first, discoloration, and second, intensity decay. Obviously the former is the appearance of pipe, which affect the life of the pipe, window profiles and other products in the same problem.

weather made our test data, and studies have shown that a large number of others, impact ACR has unmatched durability CPE, PVC pipe used in the ACR has a long-term potential economic benefits.

5, financial strength

processing, PVC materials, the melt strength of highly filled calcium carbonate, carbon black and other components of the pipe's strength has a very clear role in the group were populate the high case, the melt strength decreases, the shear and under the effect of traction, prone to melt fracture phenomenon, the formation of surface defects, resulting in decreased mechanical properties of products. ACR as molecular weight processing, good compatibility with PVC reason help to improve the financial strength of materials, to obtain high-strength products.

Second, technical indicators
