Ball bearing carbon fiber reinforced thermoplastic Meldin®

reinforcedabrasion-resistantwear-resistant

Overview
Meldin® Thermoplastics is a family of engineered thermoplastic compounds (including PPS, PAI and PEEK/PAEK chemistries) formulated to retain mechanical strength, dimensional stability and wear resistance at elevated temperatures where standard engineering plastics de-rate. Options include injection-moldable grades and limited finished/prototype shapes.

Application examples

• Aerospace & aviation components
• Space systems
• Life-science and medical-device components (non-implantable applications)
• Semiconductor manufacturing equipment
• Industrial environments requiring high-temperature, high-load or low-friction materials

Material lines (selected)

• Meldin® Thermoplastics 1000 — PPS based: proprietary PPS compounds offering chemical and thermal resistance, dimensional stability and suitability for close-clearance parts.
• Meldin® Thermoplastics 4000 — PAI based: polyamide-imide grades delivering stiffness, sustained mechanical strength at temperature, wear resistance and compatibility with common automotive and industrial fluids; available as injection-molding grades for tight tolerances.
• Meldin® Thermoplastics 5000 — PEEK/PAEK based: high-performance PAEK/PEEK formulations providing elevated tensile, compressive and flexural strength as lower-weight, corrosion-resistant alternatives to metals and ceramics; designed for high-load, tight-tolerance finished components.

Features & Benefits

• Tribological performance under aggressive PV conditions
• Suitable for dry-running and lubricated environments
• Lower density versus metals for weight reduction
• High thermal resistance and low coefficient of thermal expansion for dimensional stability
• Chemical and corrosion resistance to many industrial fluids
• Mechanical integrity and capability for high static and dynamic loads
• Available reinforced, unfilled (electrical insulation) and specialty blends optimized for wear/friction
• Injection molding capability for tight-tolerance finished parts and design flexibility
