A potentially general approach to aliphatic ester-derived PVC
The safety of flexible polyvinyl chloride (PVC) materials is now being questioned, partially due to allegations that di-(2-ethylhexyl) phthalate (DEHP), the dominant PVC plasticizer, is an endocrine disruptor and a probable carcinogen. As sustainable alternatives, aliphatic ester-derived plasticizers feature
Plasticizers for the PVC industry are now also available
Plasticizers for the PVC industry are now also available based on renewable and chemically recycled feedstock April 15, 2025 BASF now offers part of its plasticizer portfolio based on circular feedstocks. For this purpose, either renewable or chemically recycled feedstock is used at the beginning of the value chain instead of fossil resources.
Payflex Series Plasticizers - High Quality Plasticizers
Plasticizers are used to enhance the overall flexibility of the product while reducing friction and making it easy for the polymer to bend and mould. Below are some of the many properties of high-quality plasticizers that we manufacture at Payal Group: They are designed to have a high boiling point. It offers stretchability, high efficiency
Highly efficient recovery of high-purity Cu, PVC, and
Thus, the developed methods allow for the successful quantitative recovery of high-purity Cu, PVC, and DINP without requiring any of the complex multistep physical separation processes involved in the conventional granulation technique for the recycling of waste wire harnesses.
Plasticizers for PVC | POLYNT
About Plasticizers for PVC. The plasticizers are organic substances with various characteristics, whose main function is to intercalate the rigid polymer structures of material such as PVC for an easy movement and flexibility, making them more precisely "plastics." The presence of plasticizers in the PVC structure will influence different
- Is there a PVC industry in Bangladesh?
- There are no PVC industries in Bangladesh except the Meghna PVC, which has not started production yet. The raw material Cl 2 of the PVC production process is produced by brine electrolysis. The brine, electricity, and maintenance cost of an electrolysis unit increases the price of PVC resin.
- How much PVC resin does Bangladesh import a year?
- Every year Bangladesh imports 280,000 MT of PVC resin worth 330 million USD/y ( Table 4 ). The amount of Cl 2 required is 145,860 MT/y. Bangladesh earns 768 million USD/y based on 280,000 MT PVC consumption/y.
- How is PVC made in Bangladesh?
- In Bangladesh, the first stage of the PVC production process combines ethylene (excluding the NG cracking process, as PVC plants import ethylene as raw material) and Cl 2 to produce ethylene dichloride, which is then converted into vinyl chloride (the basic building block of polyvinyl chloride or PVC).
- How much Cl2 is used in PVC production in Bangladesh?
- Globally, 40% of Cl 2 from chlor-alkali process is utilized in PVC production, whereas in India, it is only 6.64% and in Bangladesh, it is 0%. In recent years, the demand for PVC in Bangladesh has increased tremendously and the current plastic demand increasing rate is 8%.
- What are the opportunities of chlor-alkali industry in Bangladesh?
- Opportunities Chlor-Alkali Industry Derived By-Products in Bangladesh The by-products of chlor-alkali process, e.g., Cl 2 and H 2, have numerous applications. Previously, we have mentioned the production of PVC from the chlor-alkali-derived Cl 2. On a global scale, PVC is the third most widely manufactured synthetic polymer.
- Can chlor-alkali and PVC be integrated into a caustic industry?
- Yearly PVC piping and fitting material demand is increasing in Bangladesh at a rate of about 20%. Integration of chlor-alkali and PVC industries is a feasible solution for the sustainable development of caustic industry. The hypothesized PVC plant can consume byproduct Cl 2 of 78,000 MT/y from chlor-alkali plants.
