Chemically Resistant PP Foam Sheet 5mm-10mm for Aerospace Material Marine

Chemically Resistant IXPP Foam for Aerospace and Marine Applications

EKKOFLEX's IXPP (Irradiation Cross-Linked Polypropylene) foam sheet is a chemically resistant closed cell thermal insulation material engineered for demanding aerospace and marine environments. Through advanced electron beam irradiation cross-linking technology, the foam achieves a uniform microcellular structure with outstanding resistance to acids, alkalis, solvents, oils, and salt water corrosion.

Unlike conventional PE or EVA foams, IXPP foam maintains dimensional stability and mechanical performance in aggressive chemical environments while withstanding service temperatures up to 130°C. This makes it the preferred insulation material for aerospace components, marine vessels, offshore platforms, and chemical processing facilities.

Key Features

• Superior Chemical Resistance - Excellent resistance to acids, alkalis, solvents, oils, and fuels, ideal for harsh industrial environments.
• Salt Water & Marine Grade - Low water absorption (≤2%) and high resistance to salt water corrosion for marine and offshore applications.
• High Temperature Stability - Stable performance from -40°C to +130°C with low shrinkage, suitable for aerospace thermal management.
• Closed Cell Structure - Non-absorbent microcellular foam prevents moisture ingress and maintains insulation performance over time.
• Lightweight & High Strength - Density as low as 33 kg/m³ with excellent mechanical strength-to-weight ratio for weight-sensitive aerospace designs.
• Certified Quality - ISO 9001:2015, RoHS, and REACH certified, meeting international compliance standards.

Frequently Asked Questions

Q1: What makes IXPP foam chemically resistant?
A: IXPP foam is based on polypropylene, which has inherently high resistance to most acids, alkalis, and solvents. The irradiation cross-linking process further enhances its chemical stability and prevents degradation in aggressive environments.

Q2: Is this foam suitable for marine and salt water environments?
A: Yes. The closed cell structure limits water absorption to ≤2%, and the polypropylene base material resists salt water corrosion, making it ideal for marine vessels, offshore platforms, and coastal facilities.

Q3: Can this foam meet aerospace application requirements?
A: IXPP foam offers low density, high temperature stability (up to 130°C), low shrinkage, and low outgassing characteristics suitable for aerospace thermal insulation and component cushioning. Final material selection should be validated against specific aerospace standards.

Q4: What temperature range can this foam withstand?
A: The IXPP foam performs stably from -40°C to +130°C, with low dimensional change at elevated temperatures, making it suitable for engine rooms and high temperature insulation.

Q5: What thicknesses, widths, and lengths are available?
A: Standard thicknesses are 5mm, 8mm, and 10mm with custom thickness available. Roll widths range from 1000mm to 1500mm, and roll length can reach up to 200m. Lamination and die-cutting services are also offered.
