Requirements 1. The reason why tons of barrel manufacturers use fillers in the process of producing tons of barrels is to reduce the cost. Therefore, the requirement for fillers is that the price cannot be too high.
Requirement 2. In addition to cost savings, as mentioned before, fillers can actually improve the performance of new tons of barrels to some extent, so the ability of the fillers used to absorb plasticizers needs to be better.
Requirement 3. In order to ensure the quality of the new ton barrel, the filler is also required to have good thermal stability and light stability, quiet to the polymer and other auxiliaries, no chemical reaction, and no serious damage to the processing performance.
