IMDS Data Entry: Why Precise Material Reporting is Critical for Car Makers.

IMDS Data Entry: Why Precise Material Reporting is Critical for Car Makers

Problem Statement

Automotive manufacturers face increasing pressure to comply with environmental regulations and ensure material traceability. Inaccurate IMDS (International Material Data System) entries lead to non-compliance, production delays, and potential recalls. A common issue is the misreporting of polymer compositions, such as FKM vs. EPDM, which can result in chemical degradation at temperatures exceeding 200°C.

Material Science Analysis

FKM (Fluorocarbon Rubber) outperforms EPDM and NBR in high-temperature environments due to its fluorine content. Fluorine provides superior chemical resistance and thermal stability. EPDM degrades rapidly in oil-based fluids, while NBR loses elasticity above 150°C. FKM maintains a compression set below 20% at 200°C, ensuring long-term sealing performance.

Technical Specs

• FKM: Shore A Hardness: 75, Tensile Strength: 15 MPa, Elongation at Break: 200%, Temperature Range: -20°C to 200°C
• EPDM: Shore A Hardness: 70, Tensile Strength: 12 MPa, Elongation at Break: 300%, Temperature Range: -50°C to 150°C
• NBR: Shore A Hardness: 65, Tensile Strength: 10 MPa, Elongation at Break: 250%, Temperature Range: -30°C to 120°C

Technical Comparison

Material	Shore A Hardness	Tensile Strength (MPa)	Elongation at Break (%)	Temperature Range (°C)	Compression Set (%)
FKM	75	15	200	-20 to 200	20
EPDM	70	12	300	-50 to 150	35
NBR	65	10	250	-30 to 120	40
