Overview
Meldin® Thermoplastics (Omniseal Solutions) is a family of engineered thermoplastic compounds formulated to retain mechanical strength, dimensional stability and wear resistance at elevated temperatures where conventional engineering plastics deteriorate. The series is designed for injection molding of finished components and for limited prototyping shapes.

Material Families and Series

• 1000 — PPS-based compounds: chemical and thermal resistance, dimensional stability for close-clearance designs.
• 4000 — PAI-based compounds: high mechanical strength and wear resistance for metal-replacement applications requiring stiffness at temperature.
• 5000 — PAEK/PEEK-based compounds: high tensile, compressive and flexural strength; corrosion resistance and lower weight versus metals for high-load use.

Typical Applications

• Aerospace & aviation: thrust washers, structural components and parts requiring thermal resistance and reduced mass.
• Space: components for extreme temperature and demanding environments.
• Life sciences & medical devices: wear parts, insulators and structural elements in robotic or thermal-critical assemblies.
• Semiconductor & industrial equipment: electrical insulation, pump and valve components exposed to chemicals and heat.

Key Performance Attributes

• Retention of strength and dimensional stability at elevated temperatures.
• Chemical and corrosion resistance (formulation dependent).
• Good tribological and wear properties under aggressive PV conditions; capability for dry-running.
• Lower density than metals enabling weight reduction in assemblies.
• Tight tolerance capability when injection molded; available in reinforced, unfilled electrical-insulation and specialty wear-grade blends.

Processing and Product Forms

• Injection-moldable thermoplastic compounds for finished parts; limited prototype shapes available.
• Formulations tailored for machining, molding tolerance control and high PV/mechanical load performance.
