Potassium Titanate Supplier in South Africa

What Is Potassium Titanate?

Potassium titanate (K₂TiO₃) is a white inorganic compound available as a powder or as engineered whisker fibres (needle-like crystals). The whisker form has attracted significant industrial interest as a non-carcinogenic alternative to asbestos and mineral wool fibres in friction materials. Potassium titanate combines excellent thermal stability, chemical inertness, reinforcing capability, and friction-modifying properties that make it valuable in the braking and clutch industries.

Friction Materials (Brake Pads & Clutch Facings)

Potassium titanate whiskers are one of the most important ingredients in modern asbestos-free automotive brake pads, brake linings, and clutch facings. They act as a reinforcing fibre and friction modifier that improves pad wear resistance, reduces brake fade at high temperatures, and stabilises friction coefficients across a broad temperature range. Their platelet or whisker morphology creates a stable transfer film on the brake disc surface, reducing disc wear and noise.

Thermal Insulation & Refractory Uses

Potassium titanate fibres and boards provide lightweight, high-temperature thermal insulation in industrial furnaces, kilns, and aerospace applications. The material maintains structural integrity and insulating performance up to approximately 1000°C. It is used in furnace linings, insulating boards, and as a fill material in high-temperature gaskets and seals where traditional ceramic wool has performance limitations.

Composite Reinforcement & Specialty Coatings

As a reinforcing filler in polymer matrix composites, potassium titanate improves tensile strength, flexural modulus, and dimensional stability of thermoplastic components. It is used in composite parts for automotive under-bonnet applications and electrical components. In specialty coatings, its reflective properties contribute to thermal management, and it is explored as a photocatalytic material and as a coating precursor for optical and semiconductor devices.
