Product Description
Closed Cell Irradiation Cross-Linked Polypropylene (IXPP) Foam engineered for pipe insulation, combining outstanding thermal insulation performance with effective acoustic damping. The uniform closed cell structure blocks heat transfer, reduces condensation, and absorbs vibration noise in HVAC, industrial, and marine piping systems.
- Thermal Insulation: Low thermal conductivity 0.030-0.040 W/m·K (ASTM C518), reduces energy loss in hot and cold pipe systems.
- Acoustic Damping: Sound insulation ≥ 30 dB (ISO 10140-2) and damping factor 0.1-0.3, effectively absorbing vibration and pipe noise.
- Closed Cell Structure: Closed cell content ≥ 95% (ASTM D6226), water vapor transmission rate < 0.05 g/(m²·24h), resists moisture and condensation.
- Wide Temperature Range: Long-term stable from -40°C to +120°C (ISO 6722), short-term peak up to +140°C.
- Lightweight & Flexible: Easy to cut, wrap, and install around elbows, valves, and irregular pipe fittings.
- Durable & Safe: Flame retardant UL94 HF-1, low VOC emission ≤ 50 μgC/g (VDA 278), ISO 9001:2015, RoHS and REACH certified.

Q1: What is IXPP foam?
IXPP foam, or irradiation cross-linked polypropylene foam, is a closed-cell foam known for its lightweight, durable, and high-performance properties. It is produced by irradiating polypropylene, which enhances its cross-linking structure and improves mechanical strength, resilience, and dimensional stability.
Q2: What are the key properties of IXPP foam?
IXPP foam offers superior impact resistance, cushioning, and vibration damping. Its closed-cell structure ensures excellent water and moisture resistance, as well as good thermal insulation. It is lightweight, flexible, and chemically stable, making it ideal for pipe insulation, protective packaging, and acoustic damping applications.
Q3: How does IXPP foam differ from IXPE foam?
While IXPE foam is based on polyethylene, IXPP foam is made from polypropylene, providing higher rigidity and heat resistance. IXPP foam is more dimensionally stable at elevated temperatures and offers better chemical and UV resistance, making it preferred for applications requiring higher load-bearing capacity and long-term thermal stability.
Q4: Can IXPP foam be used for both hot and cold pipe insulation?
Yes. IXPP foam maintains stable performance from -40°C to +120°C, making it suitable for chilled water lines, hot water supply pipes, and low-temperature refrigeration lines. Its closed cell structure effectively prevents condensation and frost formation.
Q5: How does IXPP foam perform acoustically on pipes?
IXPP foam provides sound insulation of ≥ 30 dB in the 500-2000 Hz range (ISO 10140-2) with a sound absorption coefficient ≥ 0.6 at 1 kHz (ASTM E1050) and damping factor of 0.1-0.3, effectively reducing pipe-borne vibration and noise in HVAC and industrial systems.
Q6: Is IXPP foam environmentally friendly?
IXPP foam is non-toxic and safe for consumer use. It is not biodegradable, so proper recycling or disposal is recommended. Our production process follows ISO 9001:2015, RoHS and REACH compliance to minimize environmental impact.
Q7: Can IXPP foam be customized?
Yes. IXPP foam can be manufactured in various densities, thicknesses, colors, and surface textures. It can also be laminated, die-cut, or shaped to meet specific industrial needs, ensuring optimal thermal insulation, acoustic damping, and structural support for diverse piping systems.
