Cross-Linked Polyethylene (IXPE) Tapes
-- Steady & Reliable Manufacturer --
Technical Overview
Irradiated Cross-Linked Polyethylene (IXPE) foam tapes are premium, closed-cell materials created through a cross-linking process using electron beam irradiation followed by controlled expansion. This process yields a microcellular structure with extremely fine, uniform cells, resulting in a smooth surface finish, high mechanical strength, and excellent thermal stability.
IXPE's fine structure provides high shock absorption and vibration damping with less thickness compared to non-cross-linked foams. It is resistant to water, common chemicals, and maintains performance across a wide temperature range. Key features include low thermal conductivity (excellent insulator), low compression set, and a high strength-to-weight ratio, making it suitable for precision-gasketing in electronics and high-end appliances.
Why Choose Us
Differentiating Attributes
- Ultra-Fine, Uniform Cell Structure: This microcellular design provides a smoother contact surface and superior resistance to permanent compression set compared to standard chemical cross-linked PE (XPE).
- Excellent Shock Mitigation: Delivers high energy absorption per unit volume, providing effective cushioning and protection with minimal material thickness.
- High Thermal Stability: Maintains physical properties and dimensional stability across a broad temperature range, making it reliable for components exposed to internal heat generation.
- Clean Conversion Capabilities: The smooth, uniform surface enables extremely clean, dust-free die-cutting and processing, essential for use in cleanroom or sensitive electronic assemblies.
- Low Odor and Low VOC: The manufacturing process minimizes volatile organic compounds, making it suitable for enclosed spaces and consumer-facing products.
- Durable Gasketing: The closed-cell nature ensures an effective air and moisture barrier, even under moderate compression.

Frequently Asked Questions
Frequently Asked Questions (FAQs)
- Q: What is the benefit of IXPE over standard XPE foam?
- A: IXPE (Irradiated) has a significantly finer, more uniform cell structure than standard XPE (Chemically Cross-Linked). This leads to better mechanical strength, smoother surfaces, and superior shock absorption performance.
- Q: Is IXPE suitable for exterior applications?
- A: While IXPE has good chemical stability, its UV resistance is comparable to standard PE foam. For long-term exterior use, it requires a UV-resistant film laminate or coverage to prevent degradation.
- Q: Can IXPE be used as a structural adhesive?
- A: No. IXPE's primary function is cushioning and sealing. It provides no structural bonding capacity. It should be paired with high-performance double-sided acrylic tapes if structural strength is needed alongside cushioning.
- Q: Why is IXPE preferred in electronics over other foams?
- A: Its fine cell size allows for precision die-cutting, its low compression set ensures long-term fit, and its high shock absorption protects delicate internal components, making it a reliable choice for high-value electronics.
