This paper presents a new technique which uses the principle of Fuzzy Min-Max composition for the polymer composites and also it gives more information about electrically resistant polymer.A.Zadeh introduced the concept of fuzzy set theory in 1965,Fuzzy set theory is an extension of classical set theory. In every day content most of the problems involve imprecise concept. To handle the imprecise concept. Fuzzy relations are significant concepts in Fuzzy Theory and have been widely used in many fields such as fuzzy clustering, fuzzy control and uncertainly reasoning. They also play an important role in fuzzy diagnosis and fuzzy modeling. Fuzzy relations are used in practice, how to estimate and compare them in a uncertainly measurements of fuzzy relations have been done by some researches. Similarity measurement of of uncertainly was introduced by Yeager who also discussed its application.
