Sulphur is a bright yellow naturally occurring element with the symbol S and atomic number 16 Its a versatile and essential material used in various industrial applications due to its reactive and unique properties Primary Characteristics Appearance Bright yellow crystalline solid in its elemental form Odor Typically odorless but when burned it produces a characteristic rotten egg smell due to the formation of sulphur dioxide Solubility Insoluble in water but soluble in carbon disulphide and other nonpolar solvents Melting Point 11521C 23938F Forms Grades Sulphur can be found in various forms and grades including Elemental Sulphur Typically extracted from natural gas and oil Agricultural Sulphur Finegrade sulphur used in agriculture to adjust soil pH Pharmaceutical Grade Ultrapure sulphur for medical applications Applications Chemical Industry Key ingredient in the manufacture of sulphuric acid the most widely produced industrial chemical Agriculture Used as a soil conditioner and as a component in certain fertilizers Pharmaceuticals An ingredient in some skin treatments particularly for conditions like acne and dandruff Rubber Industry Used in vulcanization a process that hardens rubber Pulp Paper Industry Used in the Kraft process to break down wood components Advantages Essential for Life An important element for all living cells playing a crucial role in the functionality of vitamins enzymes and amino acids Industrial Utility Forms the backbone of numerous chemical reactions and processes Environmental Role Used in flue gas desulphurization to reduce sulphur emissions from power plants Note When procuring or using sulphur its essential to specify the desired grade or form to ensure suitability for the intended application
Rubber bumpers are widely used in various applications. They are defined as devices used to absorb shock between two objects. The most common application of bumpers is in vehicles and vehicles yards. A bumper is made of Natural rubber and synthetic rubber blended with reinforcement materials. These bumpers are widely used because they are susceptible to damage from small contacts. They are considered to be elastomeric hardware devices that are used for edge protection, cushioning, and impact absorption. Bumper dimensions are varied in length, width and height Bumpers have a specific engineering design to absorb heavy load and it is released without damage also bumper should have elastic properties as well as the required hardness. Easy mounting with nut and bolt for application. Bumpers are protected from weather, ozone, UV and oxygen conditions and we can design customer requirements. Size :L-200x80x80mm Materials : SBR & NR Hardness : 60-65Shore Advantages They provide protection to surfaces and allow spacing and ventilation. The vibration in equipment is controlled by using a bumper. The rubber bumper also offers sliding resistance. These bumpers absorb and deliver momentum during collisions, which reduces the effect of collision. They protect the surfaces from scratches and skidding. The main advantage of rubber and plastic bumpers is that they can be manufactured in the desired colors. Applications They are used to provide protection for safety-related equipment like taillights, headlamps, and parking lights in low-speed collisions. Bumpers offer reduced sound qualities for cabinets and vanity doors. To use installation heavy machine. Heavy-duty rubber dock bumpers are used for both vehicle and loading dock applications. Material -Natural Rubber/Synthetic rubber Properties- Shock absorbing, Vibration Isolation, damping, UV Protection Application-Heavy trucks, container trailers, machinery, dock yards, container yards, unloading ramps Rubber bumper is thick article
