Steam Resistant Silicone – long chain functional polymer surface treatments
Examples of longer chained functional polymer surface treatments for fumed silica include: Silane coupling agents: Silane coupling agents are widely used to modify the surface of fumed silica particles. These agents typically have a longer chain length (e.g., C18) and contain functional groups such as amino, epoxy, or methacrylate. The silane coupling agent reacts with

Plasticity: Free Volume, Gel, Lubricity Theories
The lubricity theory, free volume theory and the gel theory are three theories that explain the plasticization of rubber compounds. The lubricity theory suggests that plasticizers improve the lubrication between the polymer chains in the rubber compound, which allows for easier movement and greater flexibility. According to this theory, the plasticizer molecules are inserted between

Plasticization
What is Plasticization? Plasticization of a rubber compound refers to the process of adding plasticizers to the rubber to improve its flexibility, workability, and other properties. A plasticizer is a chemical compound that is added to a material to make it more pliable and easier to shape. In the case of rubber, plasticizers are added

Value Stream Mapping (VSM)
Value Stream Mapping (VSM) is a lean management tool used to analyze and visualize the flow of materials, information, and activities required to bring a product or service to the customer. The objective of value stream mapping is to identify waste and opportunities for improvement within the value stream. In value stream mapping, the value

Muda – Lost Creativity
“Muda” is a Japanese term that refers to any activity that does not add value to the product or service being produced. In lean manufacturing, eliminating muda is a key strategy for improving productivity and efficiency. One type of muda that can have a negative impact on creativity in the workplace is “lost creativity.” This

C-shaped manufacturing cells
A C-shaped manufacturing cell is a type of manufacturing layout that is designed to optimize efficiency and productivity in a manufacturing process. It is named for its C-shaped configuration, which allows for a streamlined flow of materials and products through the production process. In a C-shaped manufacturing cell, the production equipment is arranged in a

Arrhenius Relation
The Arrhenius equation is a mathematical relationship that describes the effect of temperature on the rate of chemical reactions. It was first proposed by the Swedish chemist Svante Arrhenius in 1889. The equation is given by: where k is the rate constant of the reaction, A is the pre-exponential factor (or frequency factor), Ea is

Goldratt’s Critical Chain
Goldratt’s Critical Chain is a project management methodology that emphasizes the importance of identifying and managing the most critical tasks in a project in order to ensure its successful completion. The methodology was developed by Eliyahu Goldratt, a physicist and management consultant, and was first presented in his book “Critical Chain” in 1997. The critical
