The difference between plasticizer DOP and DOTP
1. Introduction of DOP plasticizer: the chemical name is dioctyl phthalate, and the raw material is phthalic anhydride and octanol. The PVC plasticized by DOP is mainly used in artificial leather, films, wires and cables, packaging materials, etc. It is a universal plasticizer which is widely used. DOTP plasticizer: The chemical name is dioctyl terephthalate, and the raw material is PT and octanol. Its liquid form is colorless and low viscosity liquid, which is mostly used in various PVC plastic products with environmental protection requirements, such as cable protective sleeve, PVC soft products, artificial leather, PVC gloves and coating industry.
2. Different advantages DOP plasticizer: For DOP plasticizer, it has good plasticization and excellent cold resistance, with a condensation point of 4℃ and normal production at -18℃. DOTP plasticizer: It has the characteristics of high temperature resistance, cold resistance, extraction resistance, non-volatility, excellent electrical insulation and good softness, and can effectively improve the hardness and deformability of products. It is an ideal substitute for DOP plasticizer.
3. DOP plasticizer with different application ranges: it is widely used in the processing of high polymers such as polyvinyl chloride resin, acetic acid resin, rubber and ABS resin, and can also be used in dyes, dispersants, paints, etc. DOTP plasticizer: Because of its high temperature resistance and high insulation performance, it is suitable for various products, such as producing temperature-resistant 70C cable material, or replacing DOP plasticizer in pvc artificial leather, PVC film, packaging materials, wires and cables, etc., and can also be used as softener in neoprene, nitrile rubber, EPDM and other products.
4. DOP plasticizer with different environmental protection levels: a small amount of inhaled DOP plasticizer will cause shortness of breath and increased heart rate, and a large amount of inhaled DOP plasticizer will cause central system disorder and gastrointestinal discomfort, which will even seriously affect fetal development and cause deformity. At present, European and American countries have strictly controlled the use of DOP plasticizer. If it is exported from China, it needs to undergo quality inspection to ensure that it meets environmental protection standards. DOTP plasticizer: DOTP is a p-benzene product, which meets the requirements of the European Union and can be used instead of DOP. It is an ideal substitute for DOP.
