Solution

In the fabrication process, during extrusion, it is necessary the polymer should maintain its position. This is applied to make high quality fabrics for like bullet proof jackets. During such condition when a force applied (or a bullet fired), the force is required to applied in just the opposite direction. In such way all polymers will meet together to make the greatest resistance against the applied force. So in fabrication the more force is needed to break their resistance force for heating and molding them into special required shapes.
