On February 14, the Ministry of Industry and Information Technology announced a list of key protection materials for epidemic prevention and control. Among them, we can see that coated spunbond fabrics, breathable films, and meltblown non-woven fabrics are used as medical protective clothing, medical masks, goggles, gloves, and medical The current market demand for important raw materials for epidemic prevention materials such as equipment, pharmaceutical packaging, and disinfection supplies has skyrocketed and the supply exceeds demand.

Increased demand for meltblown PP non-woven fabrics

As a key raw material for masks and medical protective clothing, melt-blown PP non-woven fabrics are in great demand as the number of manufacturers of epidemic prevention materials such as masks and protective clothing increases. Many manufacturers even sighed "I have a mask machine but no meltblown cloth"!

It is understood that at present, many domestic companies have some experience in the production line of meltblown non-woven fabrics, but the cost of production equipment is still high, and ordinary companies cannot immediately plan and put into production, unlike the automated production of mask machines. Line planning. Meltblown cloth is difficult to find because of the supply of raw materials, the lack of equipment production lines, the low output, the late resumption of work, and the large demand.

In terms of raw materials, only Dawn, Shengjin, Basel, etc. were supplied before the Spring Festival. In recent days, many domestic modification manufacturers have also introduced meltblown modified materials, which can ease the shortage of supply to a certain extent.

Jushi Chemical develops meltblown modified polypropylene products

The latest meltblown modified polypropylene product 5002MB1500 developed by Jushi Chemical can meet the production requirements of meltblown non-woven fabrics and help the supply of anti-epidemic protective materials!

It is understood that 5002MB1500 is a polypropylene (PP) meltblown special material prepared by using polypropylene resin as the main basic raw material and using a controlled rheological method. Its melt flow rate is very stable and the value is as high as 1500-1800g/10min. It also has the characteristics of narrow molecular weight distribution, low odor, low ash content and excellent spinning performance, which can meet the production requirements of meltblown polypropylene non-woven fabrics.

Introduction to Meltblown Technology

Since the American Exxon Company (EXXON) commercialized meltblown technology in the 1960s, meltblown spinning technology has developed rapidly. Meltblown nonwovens can be designed to achieve the required filtering function, so meltblown Spray filtration products can systematically replace traditional materials in different fields.

The ultra-fine fibers (0.015den) of meltblown nonwovens and the three-dimensional tortuous structure formed by self-bonding and entanglement of fibers in space are completely different from the fiber distribution in traditional fabrics and carded nonwovens. The sprayed non-woven fabric has the characteristics of larger specific surface area, higher porosity (≥80%), finer voids (pore size ≤1μm), and its excellent filtration performance is much higher than other ordinary filter materials.
