1.PTA raw material cost price formula PTA cost price =0.655×PX price+1200 PTA cost price =0.655×PX price+1200. The price of 0.655×PX is the cost of raw materials, and 1200 yuan is various production costs. PTA production raw material cost PTA raw material cost =0.655*PX price; The direct processing cost per unit product is about 375 yuan/ton; The unit product packaging cost is about 45 yuan/ton; The labor cost per unit product is about 20 yuan/ton; The financial cost of unit product is about 145 yuan, and the depreciation of unit product is about 305 yuan; The freight per unit product is about 50 yuan/ton; Unit product maintenance and management costs are expected to be around 60 yuan/ton. PTA is one of the important bulk organic raw materials, which is widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy. PTA is purified terephthalic acid and one of the bulk organic raw materials. Its chemical formula is C6H4(COOH)2. White crystal or powder at room temperature, low toxicity, flammable. If it is mixed with air, it will burn or even explode in case of fire within a certain limit. Soluble in alkali solution, slightly soluble in hot ethanol, insoluble in water, ether, glacial acetic acid and chloroform. The spontaneous combustion point is 680℃, and the ignition point is 384-42 1℃. The sublimation heat is 98.4kJ/mol, the combustion heat is 3225.9kJ/mol, and the density is 1.522g/cm_.

2.2. What is the production cost of PTA? At present, it is about 4500 to 4800. The main factors affecting pta price are polyester production and sales, pta plant operating rate, product inventory, international oil price, trade war and pta market fluctuation.

1.What is the relationship between PTA futures price and crude oil price?

Comparing PTA price with crude oil price, it is found that there is a serious deviation between domestic PTA price and international crude oil price. In fact, from the end of 20081February, there was an obvious "reverse change" relationship between domestic PTA prices and crude oil prices, which lasted for three months. However, from May 2007 to the end of February 2007, PTA and crude oil prices also experienced a major "reversal" for seven months. On the premise that other influencing factors are relatively stable, the influence of crude oil price will become the leading force of PTA price trend. Judging from the historical price trend, many sharp rises in PTA market are driven by soaring crude oil prices, and the sharp drop in crude oil prices will have a greater upward effect on PTA market, while the sharp drop in crude oil prices will also relax people in downstream product markets with the price increase, and PTA prices will also fall sharply because of the loss of cost support. It is undeniable that there is a strong positive correlation between the overall prices of the two.
