Tube polyamide 7000 PI Based

waterproof

A thermosetting polyimide, the Meldin® 7000 material series exhibits extremely high dimensional stability at elevated temperatures. Testing has shown that Meldin® materials have less than 0.04% variation from their original dimensions after cycling from 73°F (22.77°C) to 500°F (260°C) over a two-day period. This material is able to withstand thermal shocks very well, adding to the dimensional stability of the material. One particular grade - Meldin® 7022 exhibits an extremely low coefficient of thermal expansion, resulting in a thermal expansion behavior similar to aluminum. These compounds can also be formulated with other fillers to increase the mechanical and thermal performances of the final parts. In addition, the Meldin® 7000 PI series is processed via direct forming which enhances the cost-effectiveness and productivity. The self-lubricating grades of Meldin® do not melt when exposed to high load (P), or high speed (V) applications, as compared to more traditional PTFE or thermoplastic polymers. P x V limits for Meldin® self-lubricating grades exceed 300,000 psi·ft/min (10.5 W/mm2) in dry environments and past 1,000,000 psi·ft/min (35.0 W/mm2) in liquid or grease lubricated environments.
