Polyvinyl chloride resin plasticizer
PVC plasticizer in PVC resin, with larger proportion, the more soft plastic products: when PVC plasticizer content is less than 5%, plastic products for hard PVC resin; when the plasticizer content in 15% ~ 25%, plastic products for the semi hard; when the amount is greater than 25% plastic products, soft PVC resin; plasticizer dosage is 5% to 15% will appear when the Antiplastication phenomenon, affecting the quality of the products in the preparation, should try to prevent.
The safety of acetyl tributyl citrate ATBC.
Acetyl tributyl citrate is the world recognized the nontoxic plasticizer, according to the information reported in the 10 ~ 30ml/kgG dose on rats and cats by mouth, no influence. With this product 5% and 10% diets were fed rats for 8 weeks, no abnormality was found in main organs, only in the concentration of 10% rats with diarrhea, growth slowed down. On the toxicity of ATBC, many foreign people have chronic toxicity test, also showed that acetyl tributyl citrate, both in acute and chronic sub acute, or in the test, does not cause obvious pathological process, it can be regarded as non-toxic substances.
In view of the low toxicity of acetyl tributyl citrate, the U.S. Food and Drug Administration (FDA) approved it not only as a food packaging and medical appliances plastic plasticizer, also approved it as a food additive (synthetic flavor).
Acetyl tributyl citrate has been widely used in the food packaging industry in foreign countries, in the United Kingdom, the United States, Germany, France, Holland, Italy and Japan are licensed for food packaging materials.
Acetyl tributyl citrate is mainly used for plastic PVC and vinyl chloride, two vinyl chloride copolymer (Saran resin). PVC film is widely used for packaging fresh meat and its products abroad, but also for packaging of fresh vegetables such as sandwiches, cheese, bacon, chicken and duck, ham, ham products and mushrooms. Polyvinyl chloride (PVC) film has a large oxygen permeability, which can keep the erythrocyte blood cell protein and keep meat fresh. Its surface is glossy and transparent, the food in the package is clear at a glance, and the water permeability is moderate, and the CO2 gas permeability is high. It can reduce the dehydration of fresh vegetables and extend the shelf life of vegetables.
Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
Packing method:
200KG/ net galvanized steel drum (a small pallet loaded 16 tons), 1000KG/IB (a small barrel loaded 18 tons or 23 tons of ISOTANK).
In addition, it has good sealing performance. In contrast, polyethylene film has the disadvantage of difficult to melt seal after packing meat. Acetyl tributyl citrate plasticizer Saran resin is another main purpose, is the biggest advantage of Saran thin film has good sealing performance, excellent moisture resistance and low permeability, it is resistant to acid, alkali, oil and organic solvent. In mechanical properties, it is a kind of strong ductile thin film material between soft PVC and hard PVC.
It has outstanding thermal shrinkage. It begins to shrink at 50~60 C, and reaches 20% ~ 50% at 100 C, the highest shrinkage stress at 80 C is 13 ~ 15kg/cm3. It has strong self viscosity, and has high sealing strength at high frequency heat sealing. Therefore, it is a good food packaging material. In foreign countries, it has been widely used in the packaging of fish, sausage, ham, meat, cheese, smoked products, tofu, cakes and other long-term preservation or preservation of food, and this kind of plastic film is the main plasticizer acetyl tributyl citrate.
PVC plastic medical containers are mainly infusion bottles, infusion bags, peritoneal dialysis liquid bags, blood transfusion bags and so on. Because the PVC plastic infusion containers used for clinical saline, glucose saline, water for injection, such as Liquor Dialysisintraperitoneus infusion, therefore, there should be no microorganism in the liquid through the storage period, should not have physical or chemical action with the liquid, but can not cause harm to human body.
Plastic blood bag refers to plastic bags used for collection, separation, storage and infusion of human blood and its components.
Blood bags should be colorless, transparent, soft, closed, sterile, non-toxic, and sterilize. During storage, the dissolution of blood bag components in anticoagulant or blood must conform to the standard, and limit the toxicity to the blood and the influence on the patients to the greatest extent. The currently used plasticizer for DOP, although studies suggest that the DOP in the blood of the dissolution of a small amount of red blood cells in bonding stability, reduce the permeability of erythrocyte membrane to reduce hemolysis, storage, however on dissolution of DOP toxicity in the blood also caused people pay attention to. Because DOP is considered to have the possibility of cancer, it should be limited to the use of DOP in the medical field.
ATBC has the characteristics of non-toxic and tasteless. It was widely used in medical instruments in 70s twentieth Century. Acetyl tributyl citrate has been used for PVC medical products in the United States, is a phthalate plasticizer in the medical industry ideal substitute.
