Hydroxy terminated polybutadiene (HTPB) is a polybutadiene polymer characterized by the presence of hydroxyl functional groups at its chain ends. This unique feature endows HTPB with excellent adhesion and compatibility with other ingredients, making it a preferred binder in solid rocket propellants. Its flexibility and resistance to fuel and oxidizer chemicals further contribute to its suitability for aerospace applications. HTPB's properties can be customized through the incorporation of various additives, rendering it a versatile and reliable material for the development of high-performance solid rocket propellants.

Check Digit Verification of cas no
The CAS Registry Mumber 69102-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 69102-90:
(7*6)+(6*9)+(5*1)+(4*0)+(3*2)+(2*9)+(1*0)=125
125 % 10 = 5
So 69102-90-5 is a valid CAS Registry Number.
