Custom Silicone Gaskets for Industrial Sealing Applications
Silicone gaskets are a key component in industrial sealing applications that demand temperature resistance, chemical durability, and flexibility. WH Silicone specializes in OEM production of custom silicone gaskets tailored to the needs of automotive, HVAC, electrical, and machinery clients worldwide.
🔧 Why Silicone Gaskets Are Preferred in Industrial Environments
Compared to traditional rubber seals, silicone gaskets offer superior performance in the following areas:
-
Temperature resistance：−60°C to 230°C (up to 300°C for special blends)
-
Chemical resistance：Excellent for oils, acids, UV, and ozone
-
Compression set：Maintains sealing under long-term pressure
-
Customization：Available in various hardness (30A–80A), colors, and profiles

🛠️ Material Options: HTV vs. LSR for Gaskets
| Property | HTV Silicone | LSR (Liquid Silicone Rubber) |
|---|---|---|
| Processing Method | Compression/Transfer | Injection Molding |
| Application | Larger sizes, dense parts | Thin walls, complex parts |
| Cost | Lower for simple gaskets | Better for high precision |
Our team will help you choose the right material based on compression force, temperature range, chemical contact, and application needs.
🔍 Use Case: Oil-Resistant Silicone Gasket for Pumps
A European client in the pump industry required a custom red silicone gasket with 70A hardness and resistance to hydraulic oil. WH provided:
-
A precise steel compression mold
-
Oil-resistant HTV blend
-
Monthly 20,000 pcs with QC reports
Result: Reduced leakage by 98% in the client’s final system.
