Question regarding additives for polyethylene film materials!
Thread Content
This post was last edited by arguschf on 2011-6-2 15:54. Friends who are process experts in the polyethylene field! I would like to ask the following question: 1. What grades of repackaging materials are currently produced by domestic polyethylene plants! 2. What additives are contained in it? 3. Do all antioxidants have to be Irgafos 168 and Irganox 1010? I hope friends in this field can provide guidance and exchange ideas! ! ! :handshake
At present, the main high-strength polyethylene film materials in China include DGDA-6098 produced using Qilu’s gas-phase fluidized bed technology, 7000F manufactured by Yanshan, Yangzi, and Daqing using Mitsui Oil Chemicals’ technology, J0349 and J1056 from Liaohua, as well as TR144 and TR168 from Shanghai Jinfei and Maoming Petrochemical. The primary antioxidant is usually 1010, while there are many options for secondary antioxidants, such as 626, 627, 168, and so on.
Thank you! However, as mentioned above, most of the product codes refer to low-pressure high-density polyethylene; I’m more interested in learning about high-pressure low-density polyethylene, as well as the formulations of additives used in heavy-duty packaging films and the brand names of such products.
Is it also necessary to add antioxidants to polyethylene? Isn’t it said that polyethylene does not oxidize easily?
