As industrial sectors demand materials that can withstand extreme heat, voltage, and harsh conditions, phenyl silicone rubber putty is gaining traction as a reliable solution for sealing and insulation in complex environments.

This semi-solid material is formulated from phenyl silicone rubber enhanced with reinforcing fillers and specialty additives. Its viscoelastic structure allows for excellent self-adhesion and remoldability, enabling consistent sealing even on irregular surfaces. Unlike conventional sealants, it maintains stable performance across a wide temperature range of -60°C to +300°C and resists degradation from heat, moisture, ozone, and arcing.

In electrical systems, phenyl silicone putty is widely used for sealing and insulating components such as bus ducts, switchgear, transformers, and inductors. Its excellent dielectric properties help block electromagnetic interference, improving system safety and operational longevity.

Beyond electrical applications, this material excels in aerospace, rail transit, and chemical protection. It provides heat-resistant sealing for pipes, access panels, and equipment housings exposed to fluctuating temperatures and corrosive agents. Its low shrinkage, non-slump characteristics, and easy application make it ideal for on-site repairs and complex part integration.

As the demand for long-life, high-reliability sealing materials continues to grow, phenyl silicone rubber putty is poised to become a core material in advanced industrial sealing technologies.
