Benefits of Huber's Surface Treated ATH and MDH Grades

Huber Engineered Materials manufactures an array of surface treated and untreated Alumina Trihydrate (ATH) and Magnesium Hydroxide (MDH) products for many applications. Surface treatment technology is one of Huber’s core competencies and delivers multiple benefits including:

  • Improved compatibility, easier dispersion leading to higher loadings
  • Uniform physical properties
  • Better wet-out between resin and inorganic additive
  • Hydrophobicity, lower water absorption
  • Better reinforcement due to coupling between inorganic additive and polymer
  • Higher tensile and flexural strengths
  • Greater impact and scratch resistance
  • Improved heat aging properties 

Examples of these benefits are shown in the data below (click on the specific benefit to learn more):
