Poly(1,4-phenylene sulfide), commonly known as PPS, is a high-performance engineering thermoplastic polymer characterized by its excellent thermal stability, chemical resistance, and mechanical properties. It is synthesized through the polymerization of p-dichlorobenzene and sodium sulfide, resulting in a linear, semi-crystalline polymer with a repeating unit of 1,4-phenylene sulfide. PPS is widely used in various industries, including automotive, electronics, and aerospace, due to its ability to withstand high temperatures, corrosive chemicals, and mechanical stress. It is also known for its flame resistance, low smoke emission, and self-extinguishing properties, making it a preferred material for applications requiring high safety standards.
The CAS Registry Mumber 9016-75-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 9016-75: (6*9)+(5*0)+(4*1)+(3*6)+(2*7)+(1*5)=95 95 % 10 = 5 So 9016-75-5 is a valid CAS Registry Number.
