25586-42-9 Usage
Uses
Used in Plastics and Resins Industry:Tris(methylphenyl) phosphite is used as a stabilizer and plasticizer for plastics and resins. Its application helps to enhance the stability, flexibility, and durability of the materials, making them more resistant to environmental factors such as heat, light, and oxygen. This results in improved performance and longevity of the final products.
The chemical properties of tris(methylphenyl) phosphite, such as its miscibility with various organic solvents and its combustible nature, make it a suitable candidate for use in the plastics and resins industry. Its ability to act as both a stabilizer and plasticizer allows it to contribute to the overall performance and quality of the materials it is used with.
Flammability and Explosibility
NonflammableCheck Digit Verification of cas no
The CAS Registry Mumber 25586-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,8 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 25586-42:
(7*2)+(6*5)+(5*5)+(4*8)+(3*6)+(2*4)+(1*2)=129
129 % 10 = 9
So 25586-42-9 is a valid CAS Registry Number.
