Data Source: Technical datasheets, industry studies (Rubber World Magazine, 2023).

Technology Advantages: Why Choose fkm Rubber Sheet?

Superior Chemical Resistance: Unaffected by most oils, fuels, acids, aromatic/aliphatic hydrocarbons—far exceeds EPDM and general silicone (measured per ASTM D471 swelling index).
High-Temperature Endurance: Continuous operation up to 250°C with minimal change in mechanical properties. Essential for refinery, turbine, and heat exchanger seals.
Outstanding Longevity: Lifecycle testing demonstrates a 2x–3x longer lifespan than comparable elastomer sheets, with fewer maintenance shutdowns.
Compliance and Safety: FDA (21 CFR 177.2600) and RoHS certified grades available for food, pharma, and potable water use.

FAQ: Technical FAQ for Professionals

Q1. What is the standard hardness available for fkm rubber sheet and how does it impact sealing?

FKM sheets are typically supplied in Shore A 60~85. Higher hardness (e.g., 80) provides greater extrusion resistance under high pressure, while lower grades offer better conformability for flange irregularities.

Q2. How does FKM compare to silicone strip seal in terms of chemical resistance?

FKM exhibits superior resistance to hydrocarbons, acids, and fuels, making it ideal for aggressive chemicals. Silicone excels in ozone, UV, and water but is less effective against oils/solvents.

Q3. Are there food and pharmaceutical compliant grades for these products?

Yes, both fkm rubber sheet and silicone strip seal can be supplied in FDA, EC 1935/2004, and LFGB (for silicone) compliant formulations, ensuring safe use with food/pharma machinery.

Q4. What is the recommended installation process for best gasket performance?

Surfaces must be clean, dry, free of oils. Use torque-based bolting sequences (per ASME B16.5), and check compression set matching according to service temperature and media.

Q5. What inspection standards are applied to factory sale EPDM sheets?

Every batch is tested per ISO 2781 (density), ISO 37 (tensile/elongation), and visual checks for porosity, delamination, and surface finish. Optional inspection with third-party (SGS, TUV) available.

Q6. Can fkm rubber sheet be customized for anti-static or conductive applications?

Yes. Carbon-black loaded FKM compounds are available, tailored for IEC 61340 compliance, ideal for electronic/electrical environments.

Q7. What is the standard lead time, and what about warranty/service?

Standard lead time is 7–12 days for regular dimensions, and 15–20 days for custom/CNC profiles. Products include a 18-month warranty covering manufacturing defects and material failures. 24/7 tech support is provided by QZseals.
