Di basic Lead Sulphate (DBLS) is a high performing heat stabilizer that is also known for its efficient characteristic of high temperature lubricant feature. This characteristic of DBLS is utilized in effective PVC processing. DBLS is known to be extensively used for ensuring longer production runs at higher rates of production. Most of the PVC pipes that are rigid along with cable industries and conduits are also known for making use of the Di Basic Lead Sulphate (DBLS). This is because of the myriad of advantages it offers in combination with other types of lubricants and lead stabilizers.

Di Basic Lead Sulphate (DBLS) is known to contain just double the amount of lead oxide –quite equivalent to the normal lead stearate. DBLS is also famous for having a corresponding higher rate of achieving effective heat stability. It helps in providing effective lubrication –especially on the surface of equipment or machines by working at elevated temperatures as well as increased speeds. There are higher chances of migration as well as the occurrence of blooming in case of DBLS in comparison to other forms of metallic stearates.

Di Basic Lead Sulphates (DBLS) is a specialized product having a low value for the refractive index. When it is used alone in case of PVC, it tends to have a low value for pigmenting value as well. It helps in the production of a high-quality, translucent product. DBLS is considered perfect for the production of both colored as well as translucent compounds. It serves to be an effective stabilizer lubricant. Through this property, it helps in ensuring improved rates of the overall production by bringing about a reduction in the existing friction. DBLS is also mostly used in combination with other forms of metallic stearates. In such a combination, DBLS is known to exhibit a higher level of efficiency by serving as an effective heat stabilizer due to the presence of its synergistic properties.
DBLS –Di Basic Lead Sulphate tends to have a wide range of applications by serving as an effective lubricant for the specific PVC compounds that are plasticized. Some of these compounds specifically include rigid PVC pipes, cable covering, PVC footwear, PVC flooring and profiles, master batches, and many other types of resistivity applications. DBLS is known to provide a free element of lead oxide as well as the presence of a free element of fatty acid content in its composition. The presence of the free lead oxide in the DBLS is known to provide excellent stability to the compound. Moreover, the free fatty acids in the DBLS helps in ensuring effective lubrication to the compound. The presence of both the components including free lead oxide and free fatty acid is responsible for contributing towards the ability of the DBLS compound to perform excellently even in elevated temperature conditions. Additional applications of DBLS include Extrusion and Calendaring operations.
