NFJ Inorganic Medium to High-Temperature Secondary Binder
production principle: During the braking process, the
stability of friction performance is maintained, replacing
some resins that lose adhesiveness at high temperatures. In
the use of friction materials, resins (or other organic
bonding materials) undergo carbonization and decomposition as
the temperature rises, leading to a decrease in bonding
performance and causing brake pads to easily slip. NFJ
Inorganic Medium to High-Temperature Secondary Binder
gradually increases viscosity with rising temperatures,
substituting for the lost bonding performance of resins; it
enhances the toughness of brake pads during braking, reducing
the occurrence of slipping at high temperatures. It can
replace certain bonding materials.
Inorganic Medium Temperature Secondary Binder Principle:
1、Stability of Friction Performance: During braking, the
secondary adhesive replaces some resin that loses its bonding
properties at high temperatures, ensuring the stability of
friction performance. Resins (or other organic bonding
materials) tend to undergo carbonization and decomposition at
elevated temperatures, leading to a reduction in bonding
performance and increased risk of brake slippage. NFJ
inorganic high-temperature secondary adhesive exhibits
increasing viscosity with temperature, compensating for the
lost bonding properties of resin and enhancing the toughness
of brake pads, thereby reducing the occurrence of slippage.
It can replace some bonding materials.
2、Improvement of Wear Resistance: Lnorganic High Temperature
Secondary Binder has fine particles, rough surface, and a
porous structure, resulting in excellent bonding properties
with other friction materials. With a hardness ranging from
**7 (Mohs hardness), it enhances the wear resistance of
friction materials. It can substitute for some wear-resistant
materials.
3、Easy Dispersion, Mixing, and Demolding: The fine and
uniform particle size of NFJ inorganic high-temperature
secondary adhesive facilitates easy dispersion when mixed
with other powder materials. Its bulk density is similar to
fibers and other friction materials, making it easy to blend
with them. This reduces friction between friction materials
and processing equipment, resulting in significant demolding
effects and improving the surface density of the final
product.
4、Low Thermal Expansion Coefficient: NFJ inorganic
high-temperature secondary adhesive exhibits no change at
**0°C.
