Naphthenic oil products
Compatible with all sorts of rubber, naphthenic oil is said to facilitate the dispersion of insoluble sulfur, the vulcanizing agent used in the production of tire rubber. Sulfur is used as a crosslinking agent during the vulcanization of rubber, and although ordinary sulfur is the most commonly used vulcanizing agent, many producers, especially those that make tire rubber, prefer to use insoluble sulfur, according to the company. Insoluble sulfur is said to avoid issues related to migration. Migration, or sulfur bloom, refers to the crystallization of sulfur on the surface of rubber. This occurs because normal sulfur is soluble and will dissolve within the rubber. When the rubber is heated during the vulcanization process, the sulfur can migrate to the surface, where it will crystallize as the rubber cools. For tire rubber and other high-end rubber products, sulfur bloom will cause problems in subsequent processing steps, according to the company. Naphthenic oil is said to be particularly suitable because it efficiently prevents reversion back to the soluble form. At the same time, it also enables the curing agent, in this case insoluble sulfur, to be properly incorporated into a wide selection of rubber.

Fluoroelastomer coating
PLV2020 is a Viton (Chemours) fluoroelastomer-based formulation in an aerosol spray can. The product is said to provide superior performance characteristics compared to other aerosol spray coatings. PLV2020 is a black, one-part coating available in a 12 ounce aerosol spray can, said to provide ease and speed of application, a smoother finish with no brush streaks, and no post-application brush clean-up. PLV2020 enables the quick application of a thin, chemically resistant, rubbery coating of Viton fluoroelastomer, according to the company. It has a higher solids content compared to other aerosol coatings for better deposition and thickness, so fewer coats are said to be required. As a Viton formulation, PLV2020 is said to provide resistance to corrosive liquids, including sulfuric, nitric and hydrochloric acids; oil and fuel; and hydrocarbons and chlorinated solvents.

Solid silicone rubber
Elastosil R plus 4350/55 solid silicone rubber is an extrudable and addition-curing silicone grade said to offer high resistance to heat. Heat stabilizers enable the solid silicone to withstand temperatures of up to 300C for several days without any substantial modifications to its elasticity or mechanical properties. Even temporary peaks of up to 400C are said to pose no problem. The solid silicone is therefore said to be suitable for components used in high heat applications in the automotive sector. Elastosil R plus 4350/55 is a silicone rubber for formulating heat-resistant, addition-curing silicone elastomers. It reveals its properties to optimum effect in combination with heat stabilizers of the Elastosil Aux Stabilizer H series which are added to the base rubber. The type of stabilizer and the amount used have a significant influence on the thermal properties of the cured rubber. The silicone grade is said to be easy to process in extruders. Elastosil R plus 4350/55 can be used to produce heat-resistant tubing and sealing profiles for use in engine compartment parts.

High-tech thermoplastics for future mobility
Hollow profile hybrid technology is said to be a further development of the classic plastic metal hybrid technology for automotive mass production. Instead of sheet metal, hollow metal profiles with round or square cross-sections are used in combination with polyamide 6 injection molding. Due to their dimensional stability, hollow profiles are said to enable hybrid parts with significantly higher torsional stiffness and strength. There is said to be an enormous potential for structural components such as cross car beams, which were not resilient enough using conventional hybrid technology. Like the classical plastic metal hybrid technology, the new process is said to be simple to realize by injection molding manufacturers. The investment for machinery and tooling is low, and cycle times are as short as for standard injection molding, according to the company. XTS2 thermostabilization (extreme temperature stabilization) increases the thermal stability of polyamide 66 to up to 230C. Important mechanical properties, such as tensile modulus, breaking stress or Izod impact strength, are said to be maintained at a high level, even at constant temperatures of up to 230C. Unlike many other thermostabilization options, the new system shows no stabilization gap between 160C and 230C. Target applications for XTS2 materials are in vehicles with high efficient combustion engines. The first product from the XTS2 product portfolio is a polyamide 66 reinforced with a 35% glass fiber reinforcement. The material will be marketed as Durethan AKV35XTS2. It is said to be ideal for the production of components such as air intake manifolds with an integrated intercooler. Another polyamide 66 with a 30% glass fiber reinforcement is also under development.

Social value of carbon black examined
Carbon black is said to be a safe, highly engineered microscopic carbon that plays an important role in many areas. Carbon black is a virtually pure, elemental carbon in the form of colloidal particles, which are microscopic and arranged in a grape-like form. Its physical appearance is that of a black, finely divided pellet or powder; individual particles of carbon black are invisible to the human eye. The size of the particles and the way they are aggregated provide specific properties to the carbon black and define its use. For example, a large particle-sized soft carbon black grade will contribute to the elasticity of the tire sidewalls, while a small particle-sized hard carbon black grade will be essential to ensure the durability of the tire's tread. Whenever one uses something that is black, it probably contains carbon black. From cars to computers, plumbing to agriculture, and banknotes to shoes, carbon black is making lives better, according to the company. It makes travel safer, communication possible, and enables access to clean water for drinking and irrigation. This company is said to lead the way in the industry in terms of pollution control technology, and aims to be as efficient as possible in the carbon mass balance efforts and sustainable practices, while providing a secure, consistent supply of the highest quality to customers across the globe. The company's campaign, called Social Value of Carbon Black, is the beginning of an initiative started by the firm for the industry at large. The company's footprint extends across 12 countries with 16 manufacturing facilities. The firm provides a complete portfolio of products across ASTM grades and specialty blacks to meet specific end requirements.
