Rheology is the study of how materials flow and deform under applied stress, influencing the processing and performance of polymers, adhesives, and coatings.

Rheology modifier is an additive used to control the flow characteristics of a material, influencing viscosity, elasticity, and overall processability in coatings, adhesives, and polymers.

Rockwell Hardness measures the depth of indentation made by a specific indenter under controlled conditions, providing a standardized way to assess the hardness of materials. […]

Rockwell hardness is a measurement of a material’s resistance to indentation under a standardized load, commonly used to determine the hardness of metals and plastics.

Rubber compounding is the process of blending rubber with additives to enhance its properties like strength, elasticity, and resistance to heat, wear, or chemicals.
