Sulfur and ph of carbon black in rubber compounds

Sulfur level and pH are important factors in the production of rubber compounds that contain carbon black. Carbon black is commonly used as a reinforcing filler in rubber compounds to improve their strength, stiffness, and abrasion resistance. Here’s how sulfur level and pH affect carbon black in rubber compounds: Sulfur level: The level of sulfur … Continued

Silane coupling agents

SI69 is a type of silane coupling agent that is commonly used in rubber compounds to improve their properties. Silica-filled rubber compounds are widely used in tire manufacturing, as they offer improved fuel efficiency, better wet grip, and reduced rolling resistance compared to traditional carbon black-filled compounds. When SI69 is added to a silica-filled rubber … Continued

Decrease Rubber Modulus; not Young’s Modulus

To decrease the modulus of a natural rubber compound, you can consider the following options: Add fillers: Fillers such as carbon black and silica can increase the stiffness and modulus of the rubber compound. Adding fillers with a lower surface area and/or smaller particle size can decrease the modulus. Use a low modulus elastomer: You … Continued

Best Elastomer for Abrasion Resistance

The best abrasion resistant elastomer depends on the specific application and the conditions under which it will be used. Here are some commonly used abrasion-resistant elastomers and their properties: Nitrile rubber (NBR): NBR is a synthetic rubber that is commonly used in industrial applications due to its high resistance to abrasion, oil, and chemicals. It … Continued

Molecular Slippage and Carbon Black Reinforcement

Molecular slippage is a phenomenon that occurs when a molecule moves through a narrow channel or pore. It was first described by Dr. Ross E. Dannenberg, a researcher at the National Institutes of Health (NIH), in the early 1980s. According to Dannenberg, when a molecule moves through a narrow channel or pore, it can sometimes … Continued

Sound Dampening Properties of Rubber

Rubber is a popular material for sound dampening due to its unique properties. The sound dampening properties of rubber are primarily due to its ability to absorb vibrations and convert them into heat energy. When sound waves hit rubber, the rubber absorbs some of the energy from the wave and converts it into heat, which … Continued
