2.1 Common Elastomer Materials

• NBR (Nitrile Butadiene Rubber): Resistant to oils, fuels, and hydraulic fluids. Ideal for automotive, hydraulic, and industrial applications.
• EPDM (Ethylene Propylene Diene Monomer): Resistant to ozone, UV, heat, and weather, suitable for water systems and outdoor applications.
• FKM/Viton: Exceptional chemical and temperature resistance, ideal for chemical processing, aerospace, and high-temperature applications.
• Silicone (VMQ): Flexible, food-grade, stable at high temperatures, for pharmaceutical and food industries.
• HNBR (Hydrogenated Nitrile Rubber): Enhanced mechanical properties for heavy-duty industrial applications.
•  

2.2 Specialty Materials

• FFKM/Perfluoroelastomer: Extreme chemical resistance and high-temperature sealing.
• TPE/TPV: Thermoplastic elastomers for flexible, lightweight, and recyclable solutions.
•  

3.1 Standard vs Non-Standard Sizes
