Grade: 168-1010<\/p>\n
Application:<\/p>\n
Oxidation is one of the degradation factors of many polymers and plastics during production and during the consumption cycle. As a result, today the producers of polymer products must use antioxidant polymer additives in order to improve the quality of their products and also prevent oxidation and destruction of their products.<\/p>\n
Antioxidants Antioxidants<\/p>\n
Objects made of polymers have the possibility of oxidative damage and their service life is shortened. Anionic oxide destruction can lead to:<\/p>\n
color change
\nLoss of clarity
\nLoss of tensile strength
\nLoss of impact strength
\ndecrease in other properties of polymers.
\nAO stands for antioxidant.<\/p>\n
In general, polymer materials are sensitive to oxygen and oxidize, including:<\/p>\n
Natural polymers
\nSynthetic polymers
\nThe resistance of different polymers to oxidation is very different:<\/p>\n
High resistance: polystyrene and polymethyl methacrylate
\nLow resistance: unsaturated polymers and elastomers
\nMethods to prevent oxidation of polymers:<\/p>\n
Modification of polymer structure: copolymerization
\nCovering end groups (mostly for polyesters)
\nPhysical stabilization by orienting the polymer (PET bottles)
\nAddition of AO: the most common method of stabilization of polymers<\/p>\n
Definition of AO:<\/p>\n
Substances that have a special chemical structure that show their effect in low concentrations and because they react faster with free radicals than the polymer, they prevent the oxidation of the polymer.<\/p>\n
<\/p>\n
Some properties that AO should have:<\/p>\n
It is in powder form and melts easily (proper distribution).
\nDo not cause color change.
\nStop the destruction process by copper, magnesium and other metals.
\nnot toxic
\nDo not run away.
\nOxidation of polymers:<\/p>\n
The oxidative degradation process is due to the reaction of free radicals with polymers, which includes 4 stages:<\/p>\n
start stage
\nRelease stage
\nSelf-catalytic stage
\nThe final stage
\nIrganox 1010 antioxidant can be used in polyolefins such as polyethylene, polypropylene, polybutene and olefinic copolymers such as ethylene-vinyl acetate copolymers. It is also recommended that this stabilizer be used in the processing of polymers such as polyesters, polyamides, and polyurethanes, polyesters, PVC, styrene homo and copolymers, ABS, elastomers such as: butyl rubber, SBS, SEBS, EPM, EPDM, as well as other synthetic rubbers and adhesives and resins. Use synthetic and natural glue and other organic material base.<\/p>\n
Plastic products that mostly contain antioxidant additives are:<\/p>\n
All types of pipes and fittings used in the building and construction industry<\/p>\n
Polyethylene films (PE films) were used in various applications from manufacturing to food packaging<\/p>\n
Products and films made of polypropylene (PP)<\/p>\n

When polymer products are placed in the environment, they undergo oxidative degradation due to the presence of oxygen, and then they turn yellow and become dry, their physical and mechanical properties decrease, and finally their service life is short. will be In fact, due to sunlight, temperature rise and processing of polymers, free radicals are created in polymers, which react with oxygen in the air and spread, and this cycle continues. As a result, polymer chains are broken over time, and their properties decrease.<\/p>\n","protected":false},"featured_media":1861,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_cat":[188],"product_tag":[],"class_list":{"0":"post-2093","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-polymer-raw-materials","8":"first","9":"onbackorder","10":"shipping-taxable","11":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/product\/2093","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/comments?post=2093"}],"version-history":[{"count":0,"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/product\/2093\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/media\/1861"}],"wp:attachment":[{"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/media?parent=2093"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/product_cat?post=2093"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/nasirchimi.com\/en\/wp-json\/wp\/v2\/product_tag?post=2093"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
