Meldin 3000 series

• Excellent Mechanical Properties
• No Post Cure
• Good Chemical Resistance
• Superior Weld-Line Strength
• Complete Mating Surface Compatibility
• Broad Design Flexibility

Meldin 3000A
Excellent multi-purpose, wear resistant material that is suitable for bearing, thrust washer, and piston ring applications. Meldin 3000A requires a minimum mating surface hardness of Rockwell C35.

Meldin 3000D
This bearing formulation is particularly well suited for use with soft mating surface materials such as soft stainless steel and aluminium.

Meldin 3000F
Components provide stiffness in addition to high wear resistance for excellent dimensional stability and good bearings properties. It is recommended for use when part requirements include high strength in thin cross sections.

Meldin 3000G
Use Meldin 3000G when the combination of high strength and electrical insulation is required. Components made from this material exhibit superior properties in tensile, flex, and resistance to deformation under load.

Meldin 3000H
This product offers the highest strength and stiffness in addition to electrical conductivity when static dissipation is required. Its very low rate of thermal expansion makes Meldin 3000H an excellent choice for high temperature bearings and components.

Meldin 7000 series

• Geometric Stability at High Temperatures
• Longer Life at Higher Loads and Speeds
• The self lubricating grades of Meldin 7000 do not melt when exposed to high load (P), or high speed(V) applications.

Meldin 7001 - Unfilled grade
A thermoplastic polyimide, Meldin 7001 is the unfilled base resin. This grade offers the maximum mechanical properties over a broad temperature range and excellent chemical resistance. It is ideal for electrical and thermal insulation applications. More ductile than ceramics and lighter in weight than metals. Meldin 7001 exhibits an outstanding strength to weight ratio making it an ideal replacement material for metals in difficult environments. It is also a popular choice for structural parts in aerospace.

Meldin 7021 - Self Lubricating grade
Meldin 7021 has 15% by weight graphite fillers, encapsulated by the base polyamide resin. With its low coefficient of friction and high heat resistance, Meldin 7021 provides our customers with the best all-round choice for high temperature bearings, seals and other low-wear applications. The bearing grade of the Meldin 7000 family with excellent wear and self-lubricating features in the most difficult environments. Excellent physical strength across its full operating temperature range, good chemical resistance and high operating PV's. Used in rigorous aircraft engine applications where high temperature and physical strength is critical.

Meldin 7003
Includes 15% molybdenum disulfide lubricating filler for wear applications that operate in a vacuum or in very dry conditions

Meldin 7022
With 40% graphite filler,the Meldin 7022 grade offers additional dimensional stability and the lowest coefficient of thermal expansion of any Meldin grade

Meldin 7211- Lowest Friction Grade
Has 10% PTFE and 15% graphite filler,which provides our lowest coefficient of friction grade.
