Offshore Wind Turbines: Corrosion-Resistant EPDM Seals for Transition Pieces.

Offshore Wind Turbines: Corrosion-Resistant EPDM Seals for Transition Pieces

Problem Statement

Offshore wind turbine transition pieces require seals that withstand prolonged exposure to saltwater, UV radiation, and temperature fluctuations (-40°C to 120°C). Standard EPDM formulations often fail due to compression set and chemical degradation in high-salinity environments.

Material Science Analysis

EPDM's ethylene-propylene backbone provides inherent resistance to UV and ozone. However, standard formulations lack sufficient filler dispersion and curing agent optimization, leading to premature failure. RubberQ's custom EPDM compound incorporates high-purity carbon black and peroxide curing agents. This enhances crosslink density, reducing compression set and improving chemical resistance.

Technical Specs

• Shore A Hardness: 70 ± 5
• Tensile Strength: 15 MPa

• Compression Set: ≤ 20% (22 hours at 100°C)

Technical Comparison

Material	Temperature Range (°C)	Compression Set (%)	Chemical Resistance (ASTM D2000)
RubberQ EPDM	-40 to 120	≤ 20	Excellent
Standard EPDM	-30 to 100	≤ 35	Good
NBR	-20 to 80	≤ 40	Fair

Standard Compliance

RubberQ's IATF 16949-certified process ensures batch-to-batch consistency. Each compound undergoes rigorous testing per ASTM D2000 and ISO 3601 standards. Surface preparation and curing parameters are tightly controlled to meet offshore wind turbine specifications.
