Polyethylene Terephthalate(PET)

Polyethylene Terephthalate(PET), a new type of energy-saving board made of polyethylene terephthalate (PET) as the core substrate, composite with inorganic flame retardant materials through micro-foaming process. The product combines the high efficiency thermal insulation performance of organic materials with the fireproof characteristics of inorganic materials, breaking through the technical bottleneck of traditional thermal insulation materials in the fire safety and thermal performance is difficult to be compatible with the realization of the double breakthrough of the B1 class flame retardant and low thermal conductivity.

PRODUCT FEATURES

Stabilized flame retardant

Through nano-scale inorganic coating technology, the PET molecular chain forms a honeycomb barrier structure, there is no molten droplet phenomenon during combustion, and the smoke toxicity level reaches AQ2, which meets the GB8624-2012 standard B1 level fire requirements.

Ultra-low thermal conductivity

The microporous structure design with closed pore rate＞92%, the thermal conductivity is as low as 0.033-0.038W/(m-K), which enhances the energy-saving efficiency by 40% compared with the traditional EPS thermal insulation system, and the ten-year attenuation of the thermal resistance retention rate＜3%.

Mechanical reinforcement

Adopting three-dimensional cross-linking reinforcement technology, compressive strength ≥200kPa, perpendicular to the board surface tensile strength ≥0.15MPa, modulus of elasticity up to 6.5MPa, and can withstand -50℃~120℃ extreme temperature difference cycle.

Eco-cycle

Raw material contains 30% recycled PET content, 100% recyclable, production energy consumption is 65% lower than traditional insulation materials, full life cycle carbon footprint is reduced by 52%, through LEEDv4.1 material certification.

Water-repellent and weather-resistant

Surface hydrophobicity ≥98%, volume water absorption ≤1.5V/V%, quality loss rate ≤3% after 50 freeze-thaw cycles, suitable for building envelope in coastal areas with high humidity.
