PVC powder is the main raw material for PVC products. It is a pure powder and does not contain any additives or other additives.
PVC granules are usually added with stabilizers, impact aids and other modifying additives. Usually you don't need to add anything after purchase, you can use it directly on the machine.

The difference between powder and granules is due to the addition of different additives and raw materials. The cheapest price in the formula is PVC powder. The current price is about 7,000 yuan / ton (price changes are very large, the specific need to see real-time manufacturers quotes), accounting for 70% of the formula. The other 30% are other raw materials. In addition to the cheaper calcium carbonate, the price of other auxiliary materials is quite expensive.

To give you a practical case, a pound of corn only costs two dollars, but to make popcorn or silked cornflakes will sell ten dollars, because people have to add different spices, but also processing fees and profits, etc. I hope the landlord can Understand the truth of this. Jiahong Plastics has produced PVC granules for nearly 30 years. In many cases, if we encounter such a customer, we will feel a headache. They always use the price of PVC powder as the price of the final PVC pellet.

Others, if we produce hard transparent PVC granules, PVC powder only needs 7,000 yuan / ton, but the stabilizer added in the import needs 80,000 yuan / ton, the added reinforcing agent should be 35,000 yuan / ton, add lubrication The agent needs 60,000 yuan / ton tons, the processing aid needs to add 46,000 yuan / ton, the addition of anti-UV aging agent needs 360,000 / ton, although the amount of each addition is not much, but in general, it accounts for a large The cost ratio, the total price will rise.

In addition, the formulation of different quality and quality requirements will vary, the price of the raw materials used will vary, and the variety will vary, so the price of the granules will vary.
