Technology, critical, importance material development

Therefore, the development of organic polymer materials was of critical importance to the success of xerographic technology (51). 

The estimated annual outflow of foreign exchange in India due to import of coumarin is in the range Rs. 60-80 million. In spite of this, no adequate efforts have been made to develop the right technology for manufacture of coumarin in India though both the critical raw materials ortho-cresol and salicylaldehyde are made in this country. If the product could be made in India, the demand could be projected around 500 tonnes per annum. Surplus quantity could easily be exported. 

Effective utilization of a critical technology requires a much closer collaboration throughout the whole chain in which the material is used. Critical technologies evolve and develop over a long period, and so they can support a broad industrial base. This relationship creates a certain inertia with respect to revolutionary change, but it certainly indicates that it is very important to stimulate and maintain evolutionary change.
