Low Thermal Conductive High Temperature PP Foam Sheet 5mm-10mm For HVAC

Low Thermal Conductive High Temperature IXPP Foam for HVAC Insulation
EKKOFLEX's IXPP (Irradiation Cross-Linked Polypropylene) foam sheet is a lightweight closed cell thermal insulation material specifically engineered for HVAC systems. Through advanced electron beam irradiation cross-linking technology, the foam achieves a uniform microcellular closed cell structure that delivers exceptional thermal insulation performance with thermal conductivity as low as 0.035 W/m·K.
Unlike traditional PE or PU foams, IXPP foam offers superior high temperature resistance (up to 130°C), excellent dimensional stability, and low moisture absorption, making it the ideal thermal barrier for HVAC ducts, air conditioning pipes, and industrial insulation applications.

Key Features

• Low Thermal Conductivity - Thermal conductivity ≤0.035 W/m·K, effectively reduces energy loss in HVAC systems.
• High Temperature Resistance - Stable performance from -40°C to +130°C, suitable for hot and cold pipeline insulation.
• Closed Cell Structure - Non-absorbent microcellular foam prevents moisture condensation on duct surfaces.
• Lightweight & Easy Installation - Density as low as 33 kg/m³, flexible and easy to cut, wrap, and install on-site.
• Customizable Thickness & Size - Available in 5mm-10mm thickness, multiple roll widths, with lamination and die-cutting services.
• Certified Quality - ISO 9001:2015, RoHS, and REACH certified, meeting international compliance standards.

Frequently Asked Questions

Q1: What is IXPP foam and how is it manufactured?
A: IXPP (Irradiation Cross-Linked Polypropylene) foam is produced by electron beam irradiation cross-linking of polypropylene, creating a uniform closed cell microcellular structure. This advanced process gives the foam superior thermal stability, chemical resistance, and mechanical strength compared with conventional PE or EVA foams.
Q2: How low is the thermal conductivity of this IXPP foam sheet?
A: The thermal conductivity is as low as ≤0.035 W/m·K, which effectively minimizes heat transfer and reduces energy loss in HVAC duct and pipeline insulation systems.
Q3: What temperature range can this foam withstand?
A: The IXPP foam performs stably from -40°C to +130°C, making it suitable for both chilled water pipe insulation and hot water/high temperature HVAC applications.
Q4: Is this IXPP foam suitable for HVAC duct insulation?
A: Yes. Its closed cell structure prevents moisture condensation on duct surfaces, while its low thermal conductivity and high temperature resistance make it an ideal thermal barrier for HVAC ducts, air conditioning pipes, and refrigeration systems.
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.
