Description of Limestone Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris. These fossils are frequently visible to the unaided eye on close examination of the stone surface, however this is […]
Description of Styrene Butadiene Rubber Styrene-butadiene rubber, often abbreviated as SBR, is a workhorse of the synthetic rubber world. Unlike natural rubber, which comes from latex tapped from trees, SBR is derived from petroleum-based chemicals. This man-made origin has several advantages. SBR is less susceptible to fluctuations in natural rubber prices and can be tailored […]
Sodium hypochlorite Description Sodium hypochlorite is a clear, slightly yellowish solution with a characteristic odor. Sodium hypochlorite has a relative density of 1,1 (5,5% watery solution). As a bleaching agent for domestic use, it usually contains 5% sodium hypochlorite (with a pH of around 11, it is irritating). If it is more concentrated, it contains […]
Introduction Nowadays, there are various products around us that are made of plastic, especially HDPE BL3 granules. In fact, it can be said that products such as plastic containers, bottles, bags, and all kinds of plastic toys are considered to be products that you can clearly see around you. Meanwhile, the common feature of all […]
Overview White Petroleum Jelly, also known as petroleum jelly or petrolatum, is a semi-solid mixture of hydrocarbons. It is a staple in skincare and household products due to its moisturizing and protective properties. This versatile product is widely used for its ability to soothe dry skin, protect minor cuts, and act as a barrier against […]
Introduction of High-Density Polyethylene (HDPE) High-Density Polyethylene (HDPE) is a type of thermoplastic polymer produced from the monomer ethylene. It is known for its high strength-to-density ratio, making it a widely used material in various applications. High-density polyethylene or HDPE is a commonly used petroleum thermoplastic and the most used of the three polyethylenes for […]
Soda Ash Description Soda ash also known as sodium carbonate is an alkali chemical refined from trona ore and a weak base. It occurs in many kinds of mineral waters and in mineral deposits of certain springs and lake brines. It most commonly occurs as a crystalline decahydrate, which readily effloresces to form a white […]
Bitumen VG 40 Description Bitumen VG 40 is a type of bitumen that is commonly used in road construction and maintenance. It is a highly viscous material that is derived from crude oil. Viscosity Grade 40 Bitumen has a higher viscosity than VG-30 bitumen, which makes it more suitable for use in areas with high […]
Viscosity Grade Bitumen 30 Description Bitumen VG 30 bitumen is a grade of viscosity bitumen used in cold climatic and high-altitude regions. This grade of bitumen is suitable for road construction in regions with 30 to 37 °C average temperature. The standard penetration value of bitumen viscosity grade VG 30 is 60 mm at 25 […]
What is Viscosity Grade Bitumen 10? Bitumen VG 10 means that your bitumen is also suitable for paving roads in a very cold and cold climate instead of the old 80/100 penetration grade. The air temperature that matches VG10 bitumen ranges from -100C to 250C. Due to the high temperatures in hot climatic zones, the […]
