Acoustic Insulation: High-Mass Rubber Sheets for Industrial Soundproofing.

Acoustic Insulation: High-Mass Rubber Sheets for Industrial Soundproofing

Problem Statement

Industrial soundproofing requires materials that combine high mass, durability, and resistance to environmental stressors. Conventional rubber sheets fail under prolonged exposure to oils, high temperatures, and mechanical compression, leading to acoustic performance degradation.

Material Science Analysis

EPDM rubber excels in soundproofing due to its high mass and resilience. Its saturated polymer backbone provides superior resistance to oxidation, ozone, and weathering. Unlike NBR, EPDM lacks polar groups, ensuring compatibility with oils and chemicals. Its molecular structure allows for high filler loading, enhancing mass and damping properties.

Technical Specs

• Material: EPDM
• Shore A Hardness: 70 ± 5
• Tensile Strength: 12 MPa
• Elongation at Break: 300%
• Temperature Range: -40°C to 150°C
• Compression Set: 25% (70 hours at 100°C)
• Chemical Resistance: Excellent resistance to oils, acids, and alkalis
