Phenolic Foam Board: High-Performance Insulation for Industrial Projects
Trusted Phenolic Foam Board Manufacturer for Insulation and Industrial Fabrication
Xiaolong makes Phenolic Foam Boards. These boards address major challenges in industrial insulation. They are lightweight and easy to install. Plus, they offer strong fire resistance, low water absorption, and long-lasting stability. Many buyers face issues with insulation boards. The boards can soften in heat. They may absorb moisture during transportation. They can also crack when handled. These problems can cause expensive rework and delays in projects.
Xiaolong engineers its Phenolic Foam Board to address these pain points. Xiaolong makes each batch with strict process control. This gives customers a consistent, closed-cell structure. The Phenolic Foam Board is suitable for a range of applications. It’s great for construction, cold-chain, marine, and equipment insulation. Xiaolong has years of manufacturing experience. It also has a steady supply chain for raw materials. Xiaolong is a reliable partner for buyers seeking consistent quality for bulk orders.

Key Advantages of Phenolic Foam Board
High-Temperature Flame-Retardant Formula
The closed-cell phenolic resin stops flames from spreading. It also self-extinguishes quickly when the ignition source is gone.
Keeps its shape and strength even in high heat. This lowers the fire risk in systems that use it.
Modification for Balanced Toughness and Machinability
A modified resin system boosts flexural toughness. This reduces the risk of cracking during cutting, drilling, and on-site fabrication.
You can cut, shape, and fit boards with standard tools. This speeds up installation and lowers labor costs for big projects.
Sea‑Freight‑Optimized Moisture‑Proof and Anti‑Corrosion Properties
Low-water-absorption formulation keeps insulation performance strong. This holds true even extended sea-freight transport or storage in humid warehouses.
The board prevents fungal growth and stops corrosion from spreading to nearby metal parts. This helps it last longer in coastal and marine settings.
Isolated Production for Cross-Contamination Prevention
A dedicated line makes Phenolic Foam Board. This setup prevents cross-contamination with other resin or foam products.
This workflow keeps color, density, and cell structure consistent from batch to batch. This is important for large multi-container orders.

Practical Applications of Phenolic Foam Board
Building and Cold-Chain Thermal Insulation
Used as main insulation in exterior walls and roof panels needing fire-rated performance.
These are used in cold-storage warehouses and on refrigerated transport panels. They keep temperatures low and stable.
Marine and Shipbuilding Insulation
Installed in ship cabin walls and machinery-room linings to provide moisture resistance and fire safety.
Offshore platform housings exposed to constant humidity and salt air use this material.
HVAC Ductwork and Pipeline Insulation Jacketing
Preformed sections are used for HVAC duct insulation. This helps reduce energy loss in air-handling systems.
Used as an outer insulation jacket around industrial and cryogenic pipelines to limit heat gain or loss.
Common Purchasing Questions for Phenolic Foam Board
1. What thickness options are available for Xiaolong Phenolic Foam Board?
Standard thicknesses typically range from 20 mm to 100 mm. We can make custom thicknesses outside this range. Just provide your project drawings and meet the minimum order requirements.
2. Can we face the board with aluminum foil or fiberglass fabric?
Yes. Xiaolong provides different facing options. You can choose aluminum foil or fiberglass fabric. Choose aluminum foil for greater vapor resistance or fiberglass fabric for improved surface strength, depending on your needs.
3. Is Phenolic Foam Board suitable for outdoor or high-humidity environments?
Yes. Its low water absorption suits coastal, marine, and cold-chain settings. However, experts advise using a protective facing for direct outdoor exposure.
4. How is the board packaged for long-distance or overseas shipping?
Workers wrap the boards in moisture-proof film. We secure them on strong pallets or in cartons. This packaging method is designed for sea freight.
5. Can Xiaolong support project tenders that require factory test reports?
Yes. Xiaolong can share factory inspection data and test documents. This helps with tender submissions and project qualification requirements.
