Q1: What is IXPP foam?
IXPP foam, or physically cross-linked polypropylene foam, is a high-performance closed-cell material produced through electron beam irradiation crosslinking and high-temperature foaming of polypropylene resin. It offers excellent energy absorption, high temperature resistance, outstanding mechanical strength, and lightweight properties.
Q2: Why is IXPP foam ideal for HVAC insulation?
Its closed cell structure provides excellent waterproofing and moisture resistance, while low thermal conductivity (< 0.036 W/m·K) minimizes energy loss. Combined with flame retardancy (UL94 HF-1) and low VOC emission, it is a safe and efficient insulation choice for HVAC ducts and pipes.
Q3: What is the maximum service temperature of IXPP foam?
IXPP foam has a maximum long-term service temperature of 120°C with good dimensional stability up to 130°C and low thermal shrinking rate, making it suitable for hot water pipes, engine compartments, and 90-120°C heat carrier battery insulation.
Q4: Can IXPP foam be thermoformed or vacuum formed?
Yes. IXPP foam has superior processing performance and can be compounded, die-cut, thermoformed, and vacuum-formed. It also offers good thermal weldability, making it easy to fabricate into complex duct, panel, and enclosure shapes.
Q5: Does IXPP foam prevent condensation on cold ducts?
Yes. With a closed cell rate over 98% and water vapor transmission rate < 0.05 g/(m²·24h), IXPP foam effectively blocks moisture vapor and prevents condensation, frost, and mold formation on chilled water lines and cold air ducts.
Q6: 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 also has lower odor than PE foam and offers better chemical resistance and dimensional stability at elevated temperatures.
Q7: Is IXPP foam suitable for EV battery insulation?
Yes. IXPP foam can be used as thermal insulation material for 90-120°C heat carrier cycle batteries and as engine room heat insulation material. Its excellent fatigue resistance and energy absorption make it ideal for vibration damping and protection in electric vehicles.
Q8: Is IXPP foam environmentally friendly?
IXPP foam is non-toxic, low-odor, 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.
Q9: Can IXPP foam be customized?
Yes. IXPP foam can be manufactured in various expansion ratios (5-30x), densities (30-200 kg/m³), thicknesses (0.5-100mm), colors, and surface textures. It can also be laminated, die-cut, or shaped to meet specific HVAC and industrial requirements.
