Silver coated fabric is a type of textile with a silver coating applied through specific processes, commonly used in car covers, RV covers, outdoor tents, and sun-protective clothing. Its core advantages include UV protection, high weather resistance, and heat reflection.
1. Main Processes of Silver Coated Fabric
① Vacuum Sputtering Coating
This process utilizes vacuum deposition technology to evenly deposit silver or aluminum particles onto the fabric surface.
Characteristics:
· High conductivity, suitable for radiation-proof fabrics.
· High reflectivity but low abrasion resistance, making the silver layer prone to peeling.
· Higher cost, mainly used for professional protective materials.
② Coating Process
A silver-colored polyurethane (PU), acrylic (AC), PVC, or silicone layer is applied to the fabric surface.
Characteristics:
· Strong weather resistance, does not easily fade.
· Can enhance waterproof and breathable properties.
· Lower cost, suitable for outdoor covers.
③ Lamination Process
A metallic film (such as aluminum foil) or silver PE film is laminated onto the fabric using heat pressing or adhesive bonding.
Characteristics:
· Ideal for large-area sun-protection fabrics, such as car and RV covers.
· High aging resistance but low breathability.
· Customizable for transparency and reflectivity levels.
2. Properties of Silver Coated Fabric
Property | Performance |
UV Protection | Blocks over 90% of UV rays, UPF up to 50+ |
High Temperature Resistance | Reflects sunlight, reducing internal temperature by 5-10°C |
Waterproof | PU and PVC coatings provide waterproof capabilities |
Breathability | Depends on the base fabric; PU coating retains some breathability |
Abrasion Resistance | PVC coating is highly durable but may harden; PU coating is soft and scratch-resistant |
Weather Resistance | Suitable for prolonged outdoor use, resistant to aging |
Anti-static | Vacuum sputtering coating improves anti-static properties |
3. Common Base Fabric Types and Their Effects
Base Fabric | Characteristics | Suitable Applications |
Polyester | High strength, abrasion-resistant, good light resistance | Car covers, RV covers, tents |
Oxford Fabric | Tear-resistant, waterproof | High-end car covers, waterproof covers |
Nylon | Soft, lightweight, highly elastic | Sun-protective clothing, sports gear |
PP Nonwoven Fabric | Lightweight, breathable, cost-effective | Disposable protective covers |
4. Applications of Silver Coated Fabric in Cover Products
① Car & RV Covers
Oxford fabric + PU silver coating or polyester + PVC silver coating for UV protection, waterproofing, and durability.
Suitable for long-term outdoor parking, preventing interior aging.
② Motorcycle & Electric Scooter Covers
③ Outdoor Tents
④ Sun-protective Clothing & Protective Covers
5. Impact of Different Silver Coating Processes on Cost and Properties
Process | Reflectivity | Abrasion Resistance | Water Resistance | Softness | Cost |
Vacuum Sputtering | ★★★★☆ | ★★☆☆☆ | ★★☆☆☆ | ★★★★☆ | High |
PU Silver Coating | ★★★☆☆ | ★★★★☆ | ★★★★☆ | ★★★☆☆ | Medium |
PVC Silver Coating | ★★★☆☆ | ★★★★☆ | ★★★★★ | ★★☆☆☆ | Low |
Laminated Silver Film | ★★★★★ | ★★★☆☆ | ★★★☆☆ | ★★☆☆☆ | Medium |
Conclusion: How to Choose the Right Silver Coated Fabric?
High-end durable car covers: Oxford fabric + PU silver coating for UV protection, waterproofing, and abrasion resistance.
Economical car covers: Polyester + PVC silver coating for cost-effectiveness but with a stiffer texture.
Highly breathable sun-protection covers: PP nonwoven + silver film for lightweight short-term protection.
Sun-protective clothing & protective covers: Nylon + vacuum sputtering silver for lightweight breathability but at a higher cost.
