Features/benefits
Antioxidant 1135 offers excellent antioxidant performance with the convenience of a pumpable liquid. Due to its low volatility and excellent compatibility, Irganox 1135 is particularly well suited to be used in forced air cooling processes for polyurethane. The low volatility and excellent compatibility also helps to prevent fogging in automotive applications and to prevent staining of textiles (e. g. furniture, carpeting, head rests, etc.). The liquid nature and low vola-tility of Irganox 1135 make it a perfect fit where neat liquids, emulsions, suspensions, solutions or melts are an integral part of polymer manufacturing and processing. Irganox 1135 can be added before, during or after polymerization.
Product forms
colorless to slightly yellow liquid
Health & Safety
Antioxidant 1135 exhibits a very low order of oral toxicity and does not present any abnormal problems in its handling or general use. Detailed information on handling and any precautions to be observed in the use of the product(s) described in this leaflet can be found in our relevant health and safety information sheet.
Guidelines for use
Typical use levels are between 0.15 % and 0.5 %. Antioxidant 1135 can be
pumped or poured for ease of handling and efficient incorporation. It is easily
emulsifiable. Antioxidant 1135 can be added to the process stream dissolved,
dispersed, or as a pure liquid. The performance of Antioxidant 1135 can be
further enhanced by using it in combination with other phenolic antioxidants,
substituted aromatic amines, such as Irganox 5057, and/or with costabilizers
(e. g. phosphites, phosphonites, thioethers, hydroxylamines), as well as
light stabilizers (e. g. UV-absorbers, hindered amines). Performance data are
available.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 125643-61-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,4 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125643-61:
(8*1)+(7*2)+(6*5)+(5*6)+(4*4)+(3*3)+(2*6)+(1*1)=120
120 % 10 = 0
So 125643-61-0 is a valid CAS Registry Number.
