The Advantage of Sintered Brake Pads
The advantage of DeFigo's sintered Nano-metallic brake pad is its ability to retain its braking performance time after time until the end of its lifespan. DeFigo's Nano-metallic brakes are manufactured with materials those are able to withstand a thousand degrees Celsius (1000C or 1800F), and remains stable at high temperatures. In addition, lesser amount of filler or binding agent is used in the brake pad, ensuring longer service life.
In most semi-metallic brake pads, exposure to temperatures greater than 200C (400F) could result in sublimation of the phenolic resin or other materials that is used as the binder material. This will result in permanent deterioration of braking performance-- with the initial bite suffering especially. The physical integrity of the friction material is also lowered, as the friction material has increased amount of pore, the space which the binding agent used to occupy. It can result in significant chunking of the brake pad material.
The sintering process in the production cycle exposes every DeFigo brake pads to temperatures greater than 1100 degrees Celsius in vacuum to form a solid piece of friction material. This process does not require use of binder material as seen in semi-metallic brake pads, and allows more friction agent to be used in the limited volume of the friction material.
In addition, exposure to the extreme temperature (scorching, sintering action) is vital for ensuring the prolonged durability of the brake pads, and removes any unstable volatile compounds that might be present in the brake pad. The high-temperature sintering process is a costly, time-consuming production process that is not present in other brake pad production. Each set of brake pad takes up to 20 hours to manufacture as it is crafted. However, it is the only reliable way to produce high-temperature resistant brake pads and truly demonstrates the brake pad's ability to withstand very high temperatures.

How Product is Developed & Tested.
Product development
DeFigo products are developed in a friction materials lab and are subjected to extensive field testing on and off the track. The field testing is especially important for our company as it simulates conditions not possible to demonstrate on a dynamometer. Field testing subjects the products to vibrations, physical impacts, greater variation in temperature (thermal shocks) to introduction of foreign material such as water and impaction of silica (sand) dust in brake components, et cetera.
