🏗️ Product Description
The High-Performance EPS Cement Sandwich Panel with Fluorocarbon Coating is an advanced prefabricated building material designed for durability, aesthetics, and energy efficiency. It combines high-strength fiber-reinforced cement board coated with fluorocarbon paint (FEVE-based fluoropolymer), an Expanded Polystyrene (EPS) foam core for thermal insulation, and polymer-modified cement mortar for structural bonding.

❓ Frequently Asked Questions
1. What is an EPS Cement Sandwich Panel?
It is a composite building panel composed of two layers of fiber cement boards or calcium silicate boards sandwiching an expanded polystyrene (EPS) foam core. It is lightweight, fire-resistant, and offers high thermal and acoustic insulation.
2. What are the key advantages for exterior walls?
Key benefits include lightweight construction (1/10 the weight of bricks), Class A fire rating, superior weather resistance via fluorocarbon coating, and rapid modular installation which significantly reduces labor costs.
3. Is the material environmentally friendly?
Yes. Both the cement boards and EPS core are 100% recyclable. The production process releases no toxic substances and has lower carbon emissions compared to traditional construction materials.
4. What is the expected service life?
Under normal conditions and with proper installation, these panels have a service life of over 30 years. The fluorocarbon coating provides extra protection against UV, acid rain, and salt spray.
5. Can it support heavy wall-mounted objects like TVs?
Yes. With pre-installed steel anchors or appropriate fixing methods, the panels can support loads up to 30kg/m², making them suitable for shelves, TVs, and other fixtures.
6. How is the panel moisture resistance?
The panels are naturally moisture-proof. The cement surface blocks liquid water penetration, while the closed-cell structure of the EPS core ensures extremely low water absorption.
