How it’s made.

Technology

Our own process: six controlled steps take purified cotton to a released lot of military-grade nitrocellulose.

Our technology

Developed in-house.
Vetted by global experts.

Vajrashakti’s nitrocellulose process is developed in-house by our own process and engineering team, and reviewed by independent nitrocellulose and energetics experts in India and abroad.

01

In-house process

Designed by our own team around proven continuous-nitration chemistry, with modern process control at every step.

02

Independently vetted

Nitration, stabilisation, refining and release are reviewed by specialists from India and abroad before they are built.

03

Built for military grades

Engineered around JSS 1376, with every lot tested and released against its controlling specification.

Process

Six steps,
start to finish.

Each step is controlled and logged, so any lot can be traced back to its raw material.

Cleaned white cotton
Step 01

Cellulose preparation

Purified cotton linters are opened, dried and conditioned to a tight moisture limit before they meet acid.

Step 02

Nitration

Cellulose reacts with mixed nitric and sulphuric acid. Time, temperature and acid strength set the nitrogen content, and with it the grade.

Step 03

Stabilisation

Long boiling and repeated washing in stabilisation vessels remove residual acid, so the material stays stable in storage.

Pulping & blending

Conical refiners cut the fibres to the specified fineness. The pulp is then blended into large, uniform lots for batch-to-batch consistency.

Wetting & packaging

Finished nitrocellulose is wetted to 30–35% with water, then packed in sealed, labelled drums for safe storage and transport.

Test & release

In the chemical laboratory every lot is tested for nitrogen, solubility, viscosity and stability against its controlling specification, and released only when it passes. Records follow it from raw fibre to delivery.
