Introduction: Built to Brave the Elements
When sealing, cushioning, or insulating outdoor equipment, the materials you choose must endure everything the environment throws at them — UV radiation, moisture, heat, cold, and ozone. Few materials check all these boxes, but Silicone Sponge Sheets in Rolls, especially those made by Forbest, are engineered precisely for this challenge.
At Forbest, we manufacture outdoor-grade Silicone Rubber Foam Sheets that deliver exceptional durability, weather resistance, and performance consistency — even in the world’s harshest environments.
1. Why Silicone Sponge Thrives Outdoors
Silicone’s molecular stability under extreme conditions gives it a clear edge over EPDM, neoprene, and urethane foams when used outside.
Key Advantages:
| Property | Outdoor Benefit |
|---|---|
| UV & Ozone Resistance | Won’t crack, chalk, or degrade with sun exposure |
| Wide Temperature Range | Operates reliably from -60°C to +200°C |
| Closed-Cell Structure | Prevents water absorption, resists mold and mildew |
| Flame Resistance | Available in UL 94 V-0 rated foam for high-risk zones |
| Chemical Inertness | Stable in presence of oils, fuel vapors, salt spray |
“When we moved from EPDM to Forbest silicone foam, our outdoor electrical enclosures saw a 3x increase in gasket lifespan.”
— J. Ramasamy, Senior Engineer, Malaysian Solar Integrator

3.Performance That’s Lab-Tested & Field-Proven
Forbest’s Silicone Sponge Sheets are tested under real-world and simulated outdoor conditions:
-
UV Weathering (ASTM G154): Up to 1000-hour accelerated sun exposure with no degradation
-
Salt Spray Resistance (ASTM B117): Zero corrosion or discoloration after 96 hours
-
Thermal Cycling: Maintains compressibility from -50°C to +200°C over 100 cycles
-
IP Gasket Retention: Passed 24-hour submersion and 200 mm/hr rain test under pressure
Our internal lab and 3rd-party partners (SGS, TÜV) routinely certify products for OEM compliance and project-level specs.
4. Customization for Demanding Environments
No two outdoor applications are the same. Forbest supports custom foam sheet fabrication for tight tolerance and environment-specific needs:
| Custom Option | Benefit Example |
|---|---|
| Thickness Range | 0.5mm to 25mm – thick pads or slim seals |
| Roll Widths | Standard: 1000mm, Custom: up to 1300mm |
| Color Matching | Black, grey, red, blue – for branding or function |
| Adhesive Backing | High-tack or repositionable adhesives available |
| Surface Coating | Anti-stick, low-friction, or textured for specific uses |
| Precision Cutting | CNC die-cut, kiss-cut, laser patterning |
Need to pad solar panels in a high-wind region? Need low-permeability seals for telecom towers? We’ve got your back.
Real Case Example: Solar Project in the Middle East
Client: EPC contractor managing 120MW solar farm
Location: UAE desert zone, summer temps up to 54°C
Problem: Mounting bracket vibration caused micro-cracking
Forbest Solution:
-
Supplied 10mm-thick closed-cell red silicone sponge sheet
-
Laser cut to custom shape with PSA adhesive backing
-
Deployed in over 60,000 mounting locations
Result: Reduced mechanical stress and improved system stability
