Sensitivity application of the hottest plasticizer

Sensitivity application of plasticizers

children are often full of endless curiosity. When they discover a new thing, one of the first things they do is to put it in their mouth. In the first few months after birth, babies are particularly sensitive to touch (especially lips and tongue), while other sensory organs are still in the process of development, which is why children treat toys as a feast: they will happily bite animal models or suck rubber toy ducks, which are often made of polyvinyl chloride (PVC). Without these "versatile" plastics, the modern toy world is almost unimaginable

in order to ensure the safety of these soft PVC plastic toys, the European Union has issued a new regulation: from 2006, certain plasticizers are prohibited from being used in toys for children under the age of 3. In fact, since 1997, BASF has comprehensively launched a rich research project - the development of plasticizers for the above toys, with the goal of developing other plasticizers suitable for sensitive applications. Heidrun Goth, marketing specialist of BASF petrochemical products department, said, "we have successfully developed an innovative plasticizer hexamoll* DINCH that meets all health and safety standards. This enables us to provide ideal plasticizers to toy manufacturers to ensure that their toy products comply with the new EU regulations." It is impossible not to use plasticizers at all. Without them, PVC is easily broken or broken, just like dried noodles. Just as boiling water can soften spaghetti, the role of chemical additives in PVC is to lubricate the molecular chains of the polymer and soften the plastic to meet the application requirements. Hexamoll* DINCH belongs to cyclohexane 1,2-dicarboxylic acid diisopropyl ester, which is a non phthalate plasticizer. Dr. Rainer otter, an expert on toxicology and product safety of BASF, said: "BASF has invested more than 4 million euros in the centralized test of this new product. It can be said that hexamoll* DINCH is the most completely tested new plasticizer on the market so far, and its safety has been fully proved."

many large manufacturers, such as Schleich, Zapf and John, contain new plasticizers produced by BASF in the ingredients of animal toys, doll heads or football products. The design annual output of the production facilities in Ludwigshafen, Germany is 25000 tons, while the overall market demand is expected to be 260000 tons, and the annual sales value will exceed 300million euros. Hexamoll* DINCH products have obtained import licenses from the United States, Canada, Japan and many other countries. People's attention to the potential dangers of some other plasticizers will promote hexamoll* and they can also highlight the power transmission effectiveness in other applications. The market of DINCH products continues to grow

other application fields

hexamoll also plays an important role in the plastic processing industry * DINCH is the preferred plasticizer for many medical device products. The plastic products on these medical devices are often in direct contact with nutrient solutions, which will directly enter the patient's body. For example, when using intestinal nutrition therapy, it is necessary to pass through the stomach tube, and the liquid bag and hose are made of PVC. Pfrimmer Nutricia (Numico) is one of the largest manufacturers of feeding products, and has completely changed to hexamoll* DINCH products. Dagmar DEHLER of Numico marketing explained: "Considering the casual characteristics of light soil used and the concerns about the performance of some plasticizers, we want to become the first manufacturer in the industry to completely eliminate harmful substances according to the application status every 1 (3) months, so as to further ensure the safety of patients. Now with hexamoll* DINCH innovative plasticizer, a completely safe alternative product, although the price is slightly higher, we can still keep our product price low." Change. "

liquid bags and hoses are made of PVC, and nutrient solutions must be in direct contact with plastic

in German hospitals and families, about 75000 medical devices are working every day, and more and more devices begin to use new plasticizers produced by BASF, which will soon be applied to artificial respirators

hexamoll* DINCH is also applicable to products in direct contact with food. In Europe, this product has long been used in food packaging and food preservation film, and will be officially approved by the U.S. Food and Drug Administration (FDA), which can be used for products in direct contact with food

in addition, BASF has two plasticizers, which can also be used as product additives in contact with food to ensure certain safety performance. One is adipate esters as fatty esters, and the other is polyester plasticizers. As a plasticizer for PVC and other plastic products, the former is especially suitable for plastic products that need to remain flexible and soft in the environment below zero. It is suitable for items that need to be in direct contact with food. It is usually used together with the polymeric plasticizer used as food preservation film; The latter is fatty acid ester, containing polyvalent alcohol, which is a long-chain molecule. Its performance mainly depends on the choice of alcohol. It is usually used in hoses and covering films, and it is also suitable for items that need to be in direct contact with food. (end)
