As aerospace, defense electronics, and precision manufacturing demand higher sealing performance, traditional organic sealants are increasingly inadequate in extreme thermal and environmental conditions. Phenyl silicone rubber putty is gaining prominence as a next-generation material, offering excellent thermal stability, flexibility, and sealing reliability.

Excellent Temperature Resistance

Thanks to the incorporation of phenyl side chains, this silicone putty maintains integrity under wide temperature swings, from -60°C to +250°C. It is ideal for use in aircraft cabin interfaces, electrical compartment seals, radar systems, and deep-space equipment where thermal cycling is a concern.

Soft, Malleable, and Easy to Apply

Unlike rigid rubber seals, phenyl silicone putty is soft, moldable, and easy to apply by hand or automated dispensing systems. It conforms to complex surfaces and microscopic gaps, while offering great rebound and long-term aging resistance.

Reliable Sealing in Harsh Conditions

This material resists water, ozone, and UV radiation. It also delivers strong dielectric insulation and chemical inertness, making it suitable for use in high-humidity, high-vacuum, and EMI-prone environments—common in advanced electronic systems.

As advanced equipment design becomes more demanding, phenyl silicone rubber putty is increasingly being adopted to replace legacy sealants, ensuring long-term reliability and system performance.
