Recently, output of fiber materials exceeds that of wire drawing materials, and price difference between two materials is 2,000 RMB per ton. Now yield of fiber material company reaches 25%-30%. On April 11, 225 reached a new high, and transaction price exceeded 14,000 yuan/ton! On April 11, market price of S2040 fluctuated between 20,000-30,000 yuan/ton! Almost all petrochemical enterprises have planned production of refractory fiber materials, and dozens of companies have planned production of refractory fiber for first time! The recent production schedule of domestic polypropylene fiber materials is as follows:
As long as you are making masks, your value will double and tide will lift all boats! This industry is really crazy, one person wins Tao, chickens and dogs ascend to heaven! Masks, mask making machines, screws, blades, various accessories, blown fabric, blown materials, labor costs, processing costs, higher and higher! Looking at entire polypropylene market, whether blown or not, it has already begun to grow!
Where there is demand, there is a market. As long as epidemic continues, popularity of meltblown fabric, raw material for masks, will not subside! The popularity of blown fabric during this period is also very high, now your circle of friends does not post anything about blown fabric raw materials, as if you are not a plastic person. In past three months, meltblown fabric even had some of characteristics of futures, such as high volatility and high leverage. The rarest opportunity for plastics in last ten years, plastics market is on fire with blown polypropylene and all eyes are on these grades: PP 2040, Y40, H39S and Y35!
The price of meltblown fabric rose during epidemic from 20,000 yuan/ton before epidemic to highest price of 500,000 yuan/ton at present, lowest price is 430,000 yuan/ton, and average price is 470,000 yuan per ton. And order is scheduled until beginning of May. As of April 5, daily production capacity of disposable medical protective clothing has reached more than 1.5 million pieces, and daily production capacity of N95 medical masks has exceeded 3.4 million pieces. The daily production capacity is 10,000 units, and daily production capacity of portable infrared thermometers is 400,000 units.
All meltblown manufacturers are desperate to produce masks and buy raw materials, and polypropylene fiber materials are rare. Then process of preparation of blown material from melt is most important. Below is preparation process for meltblown material provided by Tough Brother:
1. Add polypropylene resin, peroxide, dispersant and coupling agent to low speed mixer in succession and mix at room temperature for 2-5 minutes at 50-100 rpm.
2. Use screw extruder to plasticize and extrude mixture obtained in step 1. The temperature of each zone in extruder is set at 170°C-230°C, and speed of main motor is 200-500 rpm. 5-15°C.
3. After hardening, use a granulator to granulate product, remove non-standard products, ventilate, and get finished product after granules are completely cooled and dried.
