Plastic gasket sheet Meldin® Thermoplastics

thermoplasticpolyamidepolymer

Overview
Meldin® Thermoplastics from Omniseal Solutions comprise a family of engineered thermoplastic compounds designed for applications requiring elevated temperature performance, dimensional stability and improved tribological behaviour. Materials are offered as injection-moldable compounds and as finished parts for limited-shape prototypes.

Material families and formulations

• Polyphenylene sulfide (PPS) formulations (Meldin® 1000 series)
• Polyamide-imide (PAI) formulations (Meldin® 4000 series)
• Polyetheretherketone / PAEK (PEEK) formulations (Meldin® 5000 series)

Series examples

• Meldin® 1000 — PPS based: chemical and thermal resistance, dimensional stability and design versatility.
• Meldin® 4000 — PAI based: elevated-temperature mechanical strength, wear resistance, candidate to replace metal components in harsh environments.
• Meldin® 5000 — PEEK/PAEK based: high tensile, compressive and flexural strength, corrosion resistance and suitability for high-load applications.

Applications

• Aerospace and aviation: thrust washers, structural components, bearings and other high-temperature components
• Space: components requiring thermal stability and mechanical performance in demanding environments
• Life science and medical components: electrical insulators, precision polymer parts
• Semiconductor and industrial applications: low-wear, chemical compatibility, pump and valve components, piston rings and other polymer components

Features & Benefits
