Low Temperature Resistant Polyurethane Cylinder Material (LT-PU)


Physical Properties of Low Temperature Resistant Polyurethane


       Low temperature resistant polyurethane cylinder material is a kind of casting polyurethane elastomer material. It not only provides better processing convenience, but also has the characteristics of low temperature resistance, cold resistance and low endogenous heat. After many practical occasions, it has been proved that this material can withstand the severe cold of -55 (℃) It has obvious advantages in applications with dynamic performance requirements. Various products manufactured with it have good performance in resilience, low temperature characteristics and oil resistance. All kinds of sealing elements manufactured with it are widely used in machinery, hydraulic pressure, locomotive parts and so on.

      Low temperature resistant polyurethane (LT-PU) is suitable for use in places with low working temperature. The chemical properties of LT-PU are similar to those of HMP, but the lowest working temperature of LT-PU is extended to -50 C. For this reason, LT-PU has excellent performance in harsh climatic conditions and is suitable for the sealing of aviation hydraulic fittings and refrigerants.


     Sealing design should first select appropriate sealing materials. The selection of sealing materials should take into account the temperature requirements of the selected materials and the chemical compatibility of sealing media, the movement speed of dynamic seals and the aging of sealing materials. Nowadays, aircraft design engineers are facing more and more severe temperature and chemical environment. A large number of Aeronautical elastic materials are used in aeronautical seals. Sealing rings can be manufactured by manual welding, automatic die casting, plant strengthening, or directly integrated into the metal parts.
