Attributes/comments: Emerald's CVC Thermoset Specialties is currently building upon its hydroxyl-terminated polybutadiene (HTPB
) commercial platform.
Studies of hydroxylterminated (HTPB
) with TDI and isophorone diisocyanate (IPDI) have examined the stress-strain behavior of the networks formed and shown the PU exhibit linear plots which are characteristic of an amorphous rubber and far better mechanical properties as compared to cross-linked polymer [14, 15].
But, the detonation velocity (D = 4.530 km/s) of FTNPEM is higher than HTPB
propellant (D = 3~4km/s)  and civil HAN explosive (D = 4 km/s) .What's more, the detonation pressure of FTNPEM (P = 9.034GPa) is high.
Currently developing an epoxidized version of its HTPB
line, Hypro 2800X95EE1 is the initial product in the platform.
Evonik will also be spotlighting the commission of its new POLYVEST[R] FIT hydroxyl-terminated polybutadiene (HTPB
) manufacturing plant in Marl.
Radhakrishnan Nair, Scientist 'G' of Vikram Sarabhai Space Centre, Thiruvanantpuram for his most significant contributions towards indigenous development of HTPB
binders and solid propellants for ISRO missions.
They had tested motors with thrusts up to 960 N with gaseous oxygen and HTPB
Reactive modifiers, crosslinkers, HTPB
polyols, epoxy resins, catalysts, and accelerators for thermoset formulations.
