PVC powder is the primary raw material of PVC products. It is pure powder without any additives and other additives.

PVC granules are generally added with stabilizers, auxiliaries and additives. In general, you don't have to add anything after you buy them, you can use them directly on the machine.

The difference between powder and granules is due to the addition of different additives and raw materials. The lowest price in the formula is PVC powder, which accounts for 70% of the formulation ratio. The other 30% is other raw materials. Except for the cheaper calcium carbonate, the prices of other auxiliary materials are quite expensive.

PVC granules are products that we add modified materials according to customer needs. The cost is higher than the market price of powder. Therefore, the price of PVC granules is relatively high. I hope readers can understand the truth. We have been making PVC granules for nearly 30 years, and our quality and reputation are top-notch in the industry.

Let me talk about the advantages of PVC granules:

(1) It is convenient to feed, and it is not necessary to install a forced feeder in the hopper.

(2) The relative density of the granules is larger than that of the powdered material, and the strength of the plastic product is good.

(3) The mixing of the resin with various solid powder materials or liquid auxiliaries is relatively uniform, and the physical properties of the plastic products are relatively uniform.

(4) Plastic products have uniform color.

(5) The particulate material contains less airborne volatiles, making the plastic products less prone to bubbles.

(6) The granules are non-polluting to the injection molding machine and the production environment.
