What are Kenospheres ?
Kenospheres, also known as Hollow Ceramic Microspheres (HCM) or Cenospheres, are inert, spherical particles primarily composed of silica and alumina. These unique microspheres are filled with negatively pressurized gas, usually carbon dioxide or nitrogen, making them incredibly heat-resistant. Unlike traditional fillers, Kenospheres offer a low surface-to-volume ratio, which results in reduced resin and binder demand. Consequently, they enable formulations with higher filler loadings, lower viscosities, and fewer VOCs. Ideal for various industries, Kenospheres are the go-to choice for enhancing product performance while cutting costs.
Typical Range of Chemical Composition
(Not for specification purposes)
Kenospheres boast remarkable physical properties that set them apart. Primarily made of silica and alumina, they exhibit high heat resistance with a melting point exceeding 1400°C. Their unique spherical shape ensures optimal flowability and low viscosity. Moreover, these microspheres are non-porous and chemically stable, offering excellent water resistance. With a high strength-to-weight ratio, Kenospheres are not only lightweight but also incredibly durable. These properties make them a versatile choice for a multitude of industrial applications.
