In the sectors of industrial cold chain logistics, cleanroom environments, and ultra-low energy consumption buildings, Polyurethane (PUR) and Polyisocyanurate (PIR) rigid foam panels are the gold standard for thermal insulation. However, as the “skin” of the panel, the quality of the facing material dictates the lifespan and structural integrity of the entire composite system.
Jinan United Perfect Building Materials Corporation has engineered the OPERFECT™ 25μm Aluminum Foil / 310g C-Glass Fabric (10×10 Mesh) composite—a heavy-duty facer specifically designed to withstand the extreme thermal and pressure challenges of continuous foaming production lines.
I. Core Technology: Overcoming High-Temperature Delamination
During the continuous foaming process of PUR/PIR boards, the chemical reaction triggers instantaneous high temperatures (ranging from 80°C to 160°C) accompanied by significant expansion pressure. Conventional facers often suffer from delamination during this critical phase.
The OPERFECT™ Advantage: Advanced Heat-Resistant Water-Based Adhesive System
- Thermal Anchoring: Our proprietary adhesive formula is specifically calibrated for phenolic and polyurethane foaming temperatures. It does not carbonize or soften under heat; instead, it facilitates a superior molecular bond with the foam core.
- Zero-Delamination Guarantee: This ensures a permanent physical lock between the aluminum foil, the glass fabric, and the PUR core. Even under long-term thermal cycling, the surface remains free from blistering or peeling.
II. Critical Application Scenarios
As a specialized surface for high-performance PUR/PIR panels, this product excels in the most demanding environments:
- Ultra-Low Temperature Cold Storage & Cold Chain Logistics:Utilizing the near-zero permeability of the 25μm aluminum foil to prevent moisture vapor from penetrating the foam core, ensuring the insulation value ($\lambda$-value) remains stable for decades.
- High-Standard Cleanrooms & Controlled Environments:The 310g glass fabric provides a smooth, rigid surface that withstands frequent chemical disinfection. It is fiber-shedding resistant, meeting the stringent hygiene requirements of the pharmaceutical and electronics industries.
- Large-Span Steel Structure Roofing & Cladding:The robust 10×10 glass mesh acts as an “external skeleton,” providing exceptional torque resistance and suppressing panel warping caused by solar thermal gradients.
- Premium HVAC Ducting Systems:Combined with Class 0 Fire Rating, it provides a durable, impact-resistant, and energy-efficient barrier for large-scale public infrastructure.
III. Key Technical Specifications (TDS)

IV. The OPERFECT™ Value Proposition
Beyond insulation, fireproofing, and durability, this facer delivers:
- Structural Reinforcement: The 310g fabric dramatically increases the puncture and impact resistance of the finished panel.
- Dimensional Stability: It suppresses the natural creep of the foam core over its lifecycle, preventing the deformation of external wall panels.
