ASTM D2000 Explained: The Universal Language for Specifying Rubber Materials.

ASTM D2000 Explained: The Universal Language for Specifying Rubber Materials

Problem Statement

Chemical degradation at 200°C in high-temperature environments causes premature failure in standard elastomers. Compression set failure in high-pressure cycles further exacerbates sealing inefficiencies.

Material Science Analysis

Standard NBR fails at elevated temperatures due to its low thermal stability. FKM excels in high-temperature applications due to its fluorine content, which provides superior chemical resistance and thermal stability. HNBR offers enhanced mechanical properties and aging resistance, making it suitable for demanding environments.

Technical Specs

• FKM: Shore A Hardness: 75, Tensile Strength: 15 MPa, Elongation at Break: 200%, Temperature Range: -20°C to 200°C
• HNBR: Shore A Hardness: 80, Tensile Strength: 20 MPa, Elongation at Break: 250%, Temperature Range: -40°C to 150°C
• EPDM: Shore A Hardness: 70, Tensile Strength: 10 MPa, Elongation at Break: 300%, Temperature Range: -50°C to 120°C

Technical Comparison Table

Material	Shore A Hardness	Tensile Strength (MPa)	Elongation at Break (%)	Temperature Range (°C)	Compression Set (%)	Chemical Resistance
FKM	75	15	200	-20 to 200	10	Excellent
HNBR	80	20	250	-40 to 150	15	Good
EPDM	70	10	300	-50 to 120	20	Moderate
