DELGRA: Reliable and Dimensional Stability Delgra has been characterising the production of Elchi for more than 30 years. Delgra formulation has a very high % of mineral filling which gives dimensional stability to Delgra powder compound. Core parts of the gas meter The main Delgra applications are for the gas meters and petrol meters. The most important part of these measurement equipments is made in thermosetting material, with high level of mineral filling with auto-lubricant effect. The dimensions of these parts have to remain constant over time despite temperature change or humidity changes or the contact with hydrocarbon in form of gas or liquid. It is perfectly reasonable that a measure as to be the same despite the outside temperature. In addition the impurities such as water, zinc, brick rubbish, which are moved with the gas or the liquid don't have to damage the measuring equipment. Parts moulded with Delgra have been worldwide standards for several years for every volume of gas meters: From Siberia to Iran, from Germany to Argentina, from Italy to Slovakia, from China to Brazil, in very environmental conditions what matters in a meter is its core pats in Delgra. Delgra is reliable over time due to Elchi experience in thermosettings.
