According to functional textiles, recently, affected by the new crown epidemic, the medical system, enterprises and consumers are expanding the purchase of disinfectants. As one of the raw materials of disinfectants, isopropanol demand has surged. At present, the global supply is in short supply, and the price has increased substantially. In some places with a small supply, isopropanol price even exceeds 4000 euros / ton, and isopropanol inventory is in short supply, The output of major suppliers has been sold out in the past two months, causing market concern.
Isopropanol soared, the auxiliary industry "worse"
Isopropanol as a small number of products, the output and inventory can not meet the existing demand, isopropanol as a commonly used solvent for textile softener block silicone oil, the consumption is large, because of the soaring price and the shortage of goods, the production, cost and price of block silicone oil softener have been greatly affected.

At present, block silicone oil is prepared by the reaction of epoxy terminated silicone oil and different types of organic amines under a large amount of isopropanol. The content of isopropanol in block silicone oil accounts for 20-60%. At present, the price of isopropanol has skyrocketed from 6000 yuan / ton in January to nearly 16000 yuan / ton, which is equivalent to 2500-6000 yuan / ton increase in the cost of block silicone oil. Under the influence of the current new crown epidemic situation, the textile printing and dyeing auxiliaries industry is facing the problem that orders are cancelled or even can't be received. In such a difficult business situation, the sharp rise in cost is undoubtedly worse.
At present, the price of isopropanol is high, the supply of goods is short, and the cost is rising sharply. We need to find a way to reduce the cost and stabilize the price without using isopropanol as a solvent to prepare block silicone oil, so as to retain customers and resist the impact of the new crown epidemic on the industry.
No need to isopropanol the multi-component copolymerization of epoxy silicone oil!
Runhe materials is committed to the research and development of block silicone oil, and now has developed a series of multi-component copolymerized epoxy silicone oil products.
As the intermediate raw material of block silicone oil synthesis, the multi-component copolymerized epoxy silicone oil has the advantages of high reactivity and so on. It can use glycol monobutyl ether and diethylene glycol monobutyl ether with low price as the solvent, and the dosage is small, only accounting for 5-10% of block silicone oil products. Compared with the block silicone oil synthesized by isopropanol, the cost can be reduced by 3000-6000 yuan / ton.
