 2. Technique indexes：

 3. Uses: The product is used as the plasticizer for solid propellants and their cladding layers, and also as the cold-resistant plasticizer for other polymers. It can improve the mechanical properties of solid propellant, decrease the Tg and increase the percentage elongation of solid propellant at low temperature. Also, it can decrease the viscosity of propellant paste, and so increase its’ fluidity and afford the composite solid propellant with good processing performance. The dosage is 10%~40% weight to the binder.

 4. Package: It’s packed in the closed metal bucket of 200 liters, net weight 180 kg/drum.

 5. Storage: Keep hermetically in a shady and ventilating place. Its shelf life is 12 months. The product could be still used if up to standard through retest after the specified date.

 6. Transportation：Prevent sunning during transportation. Keep away from strong oxidizers.

*In addition：The company could research and develop the new products according to the special demand of our clients．
