High Temperature Insulating Fireproof Putty

Updated: 2026-08-20

Overview

High-Temperature Resistant Insulating Fireproof Putty is a versatile material designed for applications requiring both thermal insulation and fire resistance. It is commonly used in electrical systems, construction, and industrial settings to seal gaps and protect against heat and flames. The putty remains stable under extreme temperatures, making it ideal for environments where conventional materials would fail. Its composition typically includes inorganic binders, refractory fillers, and other additives that enhance its insulating and fireproof properties. The material is easy to apply and can be molded into various shapes, ensuring a tight seal in complex geometries.

Physical and Chemical Properties

The putty exhibits exceptional thermal stability, withstanding temperatures up to 1000°C or higher without degrading. Its density ranges from 1.5 to 2.0 g/cm³, providing a balance between malleability and structural integrity. The material is insoluble in water and most organic solvents, ensuring long-term durability in harsh environments. Key chemical properties include low thermal conductivity, which enhances its insulating capabilities, and non-toxicity, making it safe for use in residential and commercial applications. The putty is also resistant to oxidation and corrosion, further extending its lifespan in demanding conditions.

Main Applications

This fireproof putty is widely used in electrical systems to insulate and protect wiring, junctions, and other components from heat and fire. It is also employed in construction to seal gaps around pipes, ducts, and other penetrations in fire-rated walls and floors. In industrial settings, the putty is used to protect equipment and machinery from high temperatures and flames. Its ability to maintain integrity under extreme conditions makes it a preferred choice for applications in power plants, refineries, and manufacturing facilities.

Safety and Storage

While the putty is non-toxic, it is advisable to wear protective gloves during prolonged handling to prevent skin irritation. Inhalation of dust during application should be avoided, and adequate ventilation is recommended in confined spaces. For storage, the putty should be kept in a cool, dry place, sealed in its original packaging to prevent drying out. Proper storage ensures the material remains pliable and ready for use when needed.

B2B Procurement Guide

When procuring High-Temperature Resistant Insulating Fireproof Putty, it is essential to verify that the product meets relevant industry standards for fire resistance and insulation. Suppliers should provide certifications and test reports to confirm compliance with these standards. Price ranges vary depending on the quality and supplier, with typical costs ranging from $10 to $50 per kg. Bulk purchases may attract discounts, but buyers should prioritize quality and reliability over cost savings to ensure optimal performance in critical applications.
