Dairy Industry Seals: Resistance to CIP (Clean-in-Place) Chemicals.

Dairy Industry Seals: Resistance to CIP (Clean-in-Place) Chemicals

Problem Statement

Seals in dairy processing equipment face aggressive CIP chemicals, including caustic soda, nitric acid, and hydrogen peroxide. Traditional materials degrade, leading to compression set failure and leakage.

Material Science Analysis

EPDM fails due to its poor resistance to acids and oxidizing agents. NBR degrades in alkaline environments. FKM excels due to its high fluorine content, providing superior chemical resistance and thermal stability.

Technical Specs

• Material: FKM (Fluorocarbon Rubber)
• Shore A Hardness: 75 ± 5
• Tensile Strength: 15 MPa
• Elongation at Break: 200%
• Temperature Range: -20°C to 200°C
• Compression Set: ≤ 20% (22 hours at 200°C)

Technical Comparison

Parameter	FKM	EPDM	NBR
Chemical Resistance	Excellent	Poor	Moderate
Temperature Range (°C)	-20 to 200	-50 to 150	-30 to 120
Compression Set (%)	≤ 20	≤ 40	≤ 35
Elongation at Break (%)	200	300	400

Standard Compliance

RubberQ adheres to IATF 16949 standards for batch-to-batch consistency. Materials comply with ASTM D2000 for rubber properties and ISO 3601 for dimensional tolerances.
