Oxidized Bitumen 105-35
What is Oxidized Bitumen 105-35?
Oxidized Bitumen 105-35 is a type of bitumen that has been treated with oxygen and heat in order to improve its physical properties. It is commonly used in the construction industry for various applications such as roofing, waterproofing, and pavement.The "105-35" in the name refers to the softening point and penetration value of the bitumen. The softening point of Oxidized Bitumen 105-35 is typically around 105°C, while its penetration value (a measure of the hardness of the bitumen) is around 35 dmm (decimillimeters).
Oxidized Bitumen 105-35 is characterized by its high viscosity, low ductility, and high softening point, which make it ideal for applications that require a high level of durability and weather resistance. It is also resistant to water, acid, and alkali, which makes it suitable for use in harsh environments.
Quality of Oxidized Bitumen 105-35
The quality of Oxidized Bitumen 105-35 can vary depending on a number of factors, including the source of the bitumen, the manufacturing process, and the storage and handling conditions.In general, high-quality Oxidized Bitumen 105-35 should have a consistent softening point, penetration value, and other physical properties. It should also be free of impurities such as water, dirt, and other contaminants, which can affect its performance.
To ensure the quality of Oxidized Bitumen 105-35, it is important to purchase it from a reputable supplier who can provide documentation of the product's specifications and quality control measures. It is also important to store and handle the bitumen properly, following best practices for temperature control, ventilation, and container cleanliness to prevent contamination or degradation of the product.
History of Oxidized Bitumen 105-35
The history of oxidized bitumen dates back to the early 20th century when the process of oxidation was first discovered as a means to improve the properties of bitumen. The process of oxidation involves heating the bitumen to high temperatures and blowing air through it, which causes the bitumen to react with the oxygen in the air, resulting in a harder, more durable product.
The use of oxidized bitumen became popular in the construction industry in the 1920s and 1930s, particularly for roofing and waterproofing applications. The increased durability and weather resistance of oxidized bitumen made it a popular choice for flat roofs and other structures that were exposed to the elements.
Over the years, advances in technology and manufacturing processes have led to the development of a wide range of oxidized bitumen products, including Oxidized Bitumen 105-35. Today, oxidized bitumen is widely used in the construction industry around the world, and it remains an important material for roofing, waterproofing, pavement, and other applications.
Usages of Oxidized Bitumen 105-35
Oxidized Bitumen 105-35 is commonly used in a variety of construction applications due to its high durability and weather resistance. Some of the most common uses of Oxidized Bitumen 105-35 include:
Roofing: Oxidized Bitumen 105-35 is often used as a primary component in built-up roofing systems, which are designed to provide a durable, waterproof surface for flat or low-sloped roofs.
Waterproofing: The high viscosity and low ductility of Oxidized Bitumen 105-35 make it an ideal material for waterproofing applications, such as for foundations, basements, and tunnels.
Pavement: Oxidized Bitumen 105-35 is commonly used as a binder in asphalt mixes for pavement applications, where it provides increased durability and resistance to cracking.
Coatings: The high softening point of Oxidized Bitumen 105-35 makes it suitable for use in coatings and sealants, where it provides excellent adhesion and resistance to weathering.
Adhesives: The high viscosity and adhesiveness of Oxidized Bitumen 105-35 make it a popular choice for use as an adhesive in the construction industry, particularly for bonding roofing materials and insulation.
Overall, Oxidized Bitumen 105-35 is a versatile material that is widely used in the construction industry due to its excellent physical properties and resistance to weathering and degradation.
Packing of Oxidized Bitumen 105-35
Oxidized Bitumen 105-35 is typically packed in steel drums or poly bags. The most common packaging sizes for Oxidized Bitumen 105-35 are:
Steel drums: 150 kg, 180 kg, and 200 kg drums are commonly used to pack oxidized bitumen. The drums are sealed with airtight lids to prevent moisture and air from entering, which can affect the quality of the bitumen.
Poly bags: 25 kg and 50 kg poly bags are another common packaging option for Oxidized Bitumen 105-35. The bags are made of high-density polyethylene (HDPE) and are designed to be airtight and moisture-resistant.
In addition to these standard packaging options, customized packaging can also be arranged to suit the specific needs of the customer. It is important to note that regardless of the packaging, proper storage and handling of the bitumen is critical to maintaining its quality and performance. The bitumen should be stored in a cool, dry place away from direct sunlight, heat, and moisture, and it should be handled with care to prevent damage to the packaging or the product itself.
Prices Oxidized Bitumen 105-35
The price of Oxidized Bitumen 105-35 can vary depending on several factors such as the current market demand, the location of the supplier, the quantity ordered, and the mode of transportation, among others.
As of my knowledge cutoff date of September 2021, the average price of Oxidized Bitumen 105-35 in the international market was around $500 to $550 per metric ton FOB (Free on Board) basis. However, prices may fluctuate based on supply and demand, and it is always advisable to check with multiple suppliers for current pricing and to negotiate pricing terms based on the specific requirements of the buyer.
It is important to note that while price is an important consideration, it should not be the only factor when selecting a supplier for Oxidized Bitumen 105-35. The quality of the product and the reliability of the supplier should also be taken into account to ensure that the buyer receives a product that meets their needs and performs as expected.
Delivery time and Readiness of Oxidized Bitumen 105-35
The delivery time for Oxidized Bitumen 105-35 can vary depending on several factors, including the location of the supplier, the quantity ordered, the mode of transportation, and the buyer's specific requirements. Generally, if the product is readily available, delivery can take anywhere from a few days to a few weeks, depending on the distance and mode of transportation.
