Markez® Perfluoroelastomer – Complete Overview
Markez® is a premium line of perfluoroelastomers (FFKM) developed by Marco Rubber & Plastics. Designed to deliver exceptional resistance to chemicals, heat, and steam, Markez® O-rings and seals offer a high-performance, cost-effective alternative to leading FFKM brands like Kalrez® or Chemraz®. This makes Markez® an ideal solution for applications where chemical resistance and sealing integrity are critical.
What is Markez®?
Markez® is a family of FFKM compounds engineered for environments with extreme chemical exposure and high temperatures. These elastomers combine the resilience of rubber with the chemical inertness of PTFE, making them suitable for harsh industrial processes. Markez® is used in semiconductor manufacturing, chemical processing, oil and gas, and pharmaceutical applications.
Key Features of Markez® FFKM
- Excellent Chemical Compatibility: Withstands over 1,800 chemicals, including acids, solvents, amines, and esters.
- High Thermal Resistance: Operates in temperatures up to 325°C (617°F) depending on grade.
- Low Compression Set: Maintains shape and sealing force under continuous high-stress environments.
- High Purity Grades Available: Suitable for semiconductor, pharmaceutical, and food-grade environments.
- Cost-Effective vs Other FFKMs: Provides similar performance to more expensive brands at a reduced price.
Applications of Markez® Perfluoroelastomer
Markez® seals are trusted in industries that demand high reliability:
- Semiconductor Manufacturing: Handles aggressive etching gases and plasma environments.
- Chemical Processing: Performs reliably in acid, caustic, and solvent exposure.
- Oil and Gas Exploration: Suitable for sour gas, amine, and HPHT applications.
- Pharmaceutical and Biotech: Clean and compliant for FDA and USP Class VI applications.
- Aerospace and Automotive: Withstands fuels, oils, and extreme thermal cycling.
Markez® Grades and Performance
Some popular Markez® grades include:
- Markez® Z1028: General-purpose FFKM with broad chemical and thermal resistance.
- Markez® Z1065: Designed for aggressive plasma, etching gases, and ultrapure environments.
- Markez® Z1078: High-temperature grade up to 325°C with steam and base resistance.
Each compound is engineered to provide long-term sealing reliability in specific operating environments.
