Non-toxic plasticizer
Thread Content
At present, toxic plasticizers such as DOP are commonly used in the PVC processing industry. Therefore, my country's PVC products such as toys have repeatedly encountered foreign green barriers when exporting, creating huge difficulties for my country's toy industry and other PVC product industries. Although some non-toxic plasticizers such as tributyl citrate have appeared in China, there are also problems such as serious pollution during the production process. So what is the ultimate solution for non-toxic plasticizers in our country in the future? Everyone is welcome to discuss it!
This is indeed a headache. Either it is seriously polluted or it is toxic. It is difficult to balance the two.
There is definitely a move towards non-toxic plasticizers! ! ! !
Tributyl citrate (TBC) or acetyl tributyl citrate (ATBC) is used as a plasticizer in a small amount, and there is a problem of plasticizer leakage. There are many non-toxic plasticizers, including epoxidized soybean oil and diesters. The current 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate is also a good plasticizer. The main disadvantages of non-toxic plasticizers compared to traditional plasticizers are that they are more expensive and have poor growth rate effects. The main problems at present are two: one, * * It is necessary to restrict the use of traditional plasticizers through legal forms and support and promote the application of non-toxic plasticizers. two: Increase investment in research and development funds, not to mention its relatively expensive price and poor growth effect. How can you prove that it is non-toxic? BASF develops a new plasticizer, and the toxicity test alone costs 5 million yuan. Is this something that ordinary companies can afford? It also requires * * Show some "blood".
There are many types of non-toxic (or low-toxic) plasticizers. Such as ATBC, DINCH (BASF), some glycerides, etc. However, I personally feel that the main issues are as follows:: 1. Cost. DOP is cheap and performs very well. 2. Performance. The performance, compatibility, growth efficiency, volatilization speed, migration, etc. of many non-toxic plasticizers need to be improved. 3. Rules and regulations regarding the use of DOP. a lot of * * There is no rule that DOP cannot be used in toys, packaging films and other materials. In any case, the use of non-toxic plasticizers will be a trend in the future. However, the current usage is still very small
There are many types of plasticizers, which can be divided into two categories: main plasticizers and auxiliary plasticizers according to their compatibility with polymers. The main plasticizers include phthalate esters and phosphate esters, and the auxiliary plasticizers include aliphatic dibasic acid esters, epoxy, etc. According to the structural classification of plasticizers, they can be divided into: Phthalates, aliphatic dibasic acid esters, epoxides, polyesters, etc. Non-toxic plasticizers, the main varieties are acetyl tri-n-butyl citrate, acetyl tri(2-ethylhexyl) citrate, di(2-ethylhexyl) sebacate (DOS), etc. These plasticizers are also commonly used non-toxic plasticizers for PVC.
Epoxidized soybean oil (glyceryl esters) can be used to plasticize food packaging materials.
The most ideal way: Use environmentally friendly catalytic technology to prepare non-toxic plasticizers. Not only non-toxic plasticizers, there are many things now that are environmentally friendly products and represent the future, but their current preparation processes are not environmentally friendly.
Our factory specializes in the production of non-toxic environmentally friendly plasticizers ATBC (acetyl n-tributyl citrate) and TBC (n-tributyl citrate), which are colorless and odorless, have good cold and water resistance, high boiling point, freezing point below -50°, specific gravity of about 1, heavy metals (calculated as Pb) ≤10ppm, arsenic (As) ≤3ppm. ATBC is almost 1: 1. Replaces DOP. Its speed-increasing performance is equivalent to that of DOP. Its thermal stability is equivalent to that of DINP. The surface of the product is smooth and there is no leakage. Welcome to call the business manager Mr. Jiang at 18800537943.
