Eco-friendly Lightweight Integrated Performance PET Foam Insulation
Introduction
Against the backdrop of the deep integration of materials science and industrial upgrading, thermal insulation materials are undergoing a pivotal transformation from basic heat insulation to performance integration. When traditional PVC and PS foams struggle to balance the multiple requirements of strength, temperature resistance and environmental friendliness, PET foam insulation boards—with polyethylene terephthalate (PET) resin as the base material—have emerged as a rising star in the high-performance thermal insulation sector, leveraging the synergistic advantages of their high-quality PET core and closed-cell structure.
Centered on the PET core, this type of board skillfully combines engineering plastic-grade performance with foam’s lightweight characteristics. It not only breaks through the performance bottlenecks of conventional thermal insulation materials, but also precisely meets the urgent demand for high-strength, long-life and eco-friendly materials in fields such as green buildings, new energy and high-end transportation.
Core Advantages
Application
Packaging & Shipping
To address product damage from violent shaking and collisions during long-distance transportation, we offer two protective solutions:
Standard protection: Securing products with iron frames, wooden pallets and other accessories to guarantee basic transportation safety.
Customized protection: Delivering tailored packaging based on your specific requirements, with 30% enhanced performance compared to the standard solution (e.g., specialized shock-absorbing materials, custom-fitted frames).
Core Features of PET Foam Insulation Board
Balanced High Strength and Lightweight Performance
Outstanding specific strength: The flexural strength can reach 15–35 MPa, and the compressive strength ranges from 8–25 MPa, with a density of only 0.05–0.15 g/cm³. Its strength is 50%–100% higher than that of traditional PVC foam boards. For instance, a PET foam board with a density of 60 kg/m³ can bear a load 800 times its own weight.
Excellent structural stability: It has a high heat deflection temperature of 70–100℃, far exceeding the 60℃ of PVC foam boards. It is resistant to creep in high-temperature environments and boasts superior dimensional stability, with a linear thermal expansion coefficient ≤ 8×10⁻⁵/℃.
Weather Resistance and Environmental Adaptability
Wide operating temperature range: It can work stably at temperatures from -40℃ to +120℃, meeting the insulation requirements of medium-to-high temperature applications such as solar water heaters and industrial equipment insulation.
Superior aging and chemical resistance: It is UV-resistant with an outdoor service life of ≥ 10 years, and chemically stable in a pH range of 2–12. It also has better tolerance to oils and organic solvents compared to PVC foam boards.
Multifunctional Composite Performance
Thermal insulation and soundproofing: With a thermal conductivity coefficient of 0.028–0.038 W/(m·K), it outperforms PVC foam boards (0.035–0.045 W/(m·K)) and is on par with XPS extruded boards. A 20mm-thick board can achieve an airborne sound insulation index of ≥ 30 dB, making it ideal for construction sound barriers.
Flame retardancy and environmental friendliness: It has an oxygen index (OI) of ≥ 26, and can reach B1-grade flame-retardant standard with the addition of flame retardants. It emits no toxic gases during combustion, is 100% recyclable, and complies with EU CE certification and RoHS environmental requirements.
