Meldin® Polyimide Materials
Meldin® Polyimides
High Temperature Polymer Material Solutions

Meldin® polyimide material solutions exhibit high dimensional stability at high temperatures and longer life at higher loads and speeds. With Omniseal Solutions,  total control on the process from the powder to the parts is guaranteed. This is one of our technology advantages since some of our materials are made in different ways. For example, Meldin® 7001 thermoset material is produced using three different manufacturing processes, providing an efficiency in production in terms of cost and performance for every precision application. When you need standard rods, sheets, tubes and rings, hot isostatic molding is the best method whereas direct forming is ideal for high volume, finished parts that do not need machining. Hot compression molding is used specifically for larger, machined components such as plates, tubes or rods.

Polymer solutions also include bearings, wear components, piston rings, vanes, thrust washers, seals, and custom shapes. These solutions are found in a multitude of industries such as aviation, industrial, semi-conductor, space, and life science.

Is this Material PFAS-Free*

  • Depending on the application and equipment specifications, we may be able to manufacture this solution PFAS-Free*.

  • * PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.

Material properties
Meldin® Polyimides 2000 PI Based
The legacy material range of Omniseal Solutions, the Meldin® 2000 series, offers excellent tensile strength and elongation, high compressive strength, and strong dimensional stability.
Meldin® Polyimides 6000 PI Based
The Meldin® 6000 series from Omniseal Solutions offers self-lubrication, long durability under high temperature and load, and high resistance to radiation and chemical environment. 
Meldin® Polyimides 7000 PI Based
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.
Meldin® Polyimides 8000/9000 PI Based
The Meldin® 8000/9000 Polyimide (PI) Based series is a specific range of material formulations, used in bearing cages, for example, due to its strength and its low coefficient of friction. It is a porous structure filled with lubricant.
