The Heat Mate Silicone – Black is a high modulus, permanently flexible 100% high temperature silicone designed for sealing joints and surfaces exposed to elevated temperatures. With a temperature resistance range of -50°C to 300°C, it is a practical sealing solution for fireplaces, flue components, heating appliances and other applications where both heat resistance and flexibility are important.
One of the key advantages of Heat Mate Silicone – Black is that it remains permanently flexible, allowing it to cope better with movement, expansion and contraction than more rigid sealing products. This makes it especially useful in applications where metal components or heated surfaces may shift slightly during normal operation, but still require a durable and reliable seal.
The product is ideal for use on a wide range of heat-related applications, including metal chimneys, domestic and industrial ovens, heating appliances, log burners, ducting and more. Its versatility makes it a useful product for both installation work and maintenance tasks where a high temperature silicone seal is needed across non-porous surfaces.
Another important benefit is its excellent adhesion to non-porous surfaces, helping it form a dependable bond on suitable materials. Once applied, it creates a waterproof seal, making it especially useful where protection against moisture ingress is also required alongside heat resistance.
Supplied in a 295ml cartridge and finished in Black, the silicone is practical for use in darker fireplace, flue and appliance settings where a neater visual finish is preferred.

Expert Insight
A permanently flexible high-temperature silicone is especially useful where metal parts and heated surfaces expand and contract in use, because it can maintain the seal more effectively than a rigid filler. The black finish also helps it blend more neatly into many stove, flue and chimney applications.
