Abron PIR 15 Polyimide Resin

About Abron PIR 15 Polyimide Resin

 ABRON PIR-15

 ABRON PIR-15 resin system has been developed for the manufacture of advanced composites for Space, Aerospace & Defense applications. This Polyimide based polymer can be used as a matrix material at temperatures upto 316^oC continuous applications and short excursions upto 361^oC. Of all the High Temperature materials this polyimide displays exceptional behavior in terms of processing properties, thermo-oxidative stability and retention of mechanical properties at temperatures in the 300^oC 316^oC range.

The main applications of this resin system is in the manufacture of composites for aircraft industry for engine ducts, fan blades, inner cowls, swirl frames, nozzle flaps & fins and bodies of missiles, etc.

The resin system consists of three solutions ( 50 % solid loading in Methanol ) which have to be mixed ( under specific conditions and ratios ), before use. The resin can be used for making prepregs, filament winding or moulding.

SPECIFICATIONS OF THE MONOMERS

STORAGE Store all the three parts in deep freezer for long storage, separately.

General Procedure for the preparation of the resin solution :

Keep all the three solutions at RT for couple of hours, until the contents attain RT or ~ 25^oC. Take ABRON PIR-15 Part A into a clean, dry RB flask fitted with an agitator, condenser, thermo well & heating mantle. Place a Calcium Chloride guard tube on the condenser and start agitation. While under agitation, add ABRON PIR-15 Part B into it. Heat upto 45^oC and stir ( under dry conditions ) for 90 minutes. To this solution add ABRON PIR-15 Part C and further agitate ( at 45^oC ) for 60 minutes. Cool to room temperature and use immediately.

NOTE

It is very critical to use the exact weight ratios of individual solutions & also the sequence ( as mentioned above ) to prepare the solution, in order to get the appropriate properties.
