Secondary plasticizer and co-stabilizer. To be applied as a co-stabilizer because of its good heat resistance and as secondary plasticizer for PVC formulations. Defoaming and air release additives BYK BYK-Chemie Silicone free und silicone containing air release agents for unfilled, filled, foamed as well as low fogging PVC-Plastisols.
Plasticizers for the PVC industry are now also available
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. The alternative feedstock is allocated to the sales products according to a mass balance approach.
Structure Design, Performance Simulation and Plasticizing
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved.
Flexidone – A New Class of Innovative PVC Plasticizers
PVC is one of the few thermoplastics whose hardness can be adjusted from rubber-like elasticity up to hard formulations (Franck & Knoblauch, 2005). Thus for well over 50 years plasticizers have been playing a significant role in the manufacture of soft PVC products for the most versatile applications from floor coverings to

- What is a plasticizer in PVC?
- A plasticizer reduces melt viscosity during processing. In PVC products, the glass transition temperature (Tg) and elastic modulus of PVC are also reduced. Liquids are usually called “plasticizers”, whereas solids like nitrile rubbers, compatible polyesters and some polyacrylates are called plastifiers or flexibilizers.
- What is a primary plasticizer?
- Primary plasticizers are low-volatility liquids, whose polarity is such that they are sufficiently compatible with PVC and will not be readily squeezed out of plasticized PVC by moderate pressure. They are mainly responsible for providing flexibility. Examples include: monomeric, polymeric, epoxy, specialty flame-retardant plasticizers, etc.
- How do plasticizers affect the performance of PVC products?
- Plasticizers influence the flexibility, workability, and durability of PVC products. Choosing the right type of plasticizer can enhance the performance characteristics of PVC while also addressing environmental and health concerns.
- What are plasticizers used for?
- These characteristics make PVC a versatile material used across numerous industries, from construction to healthcare. Plasticizers serve as essential additives in enhancing the performance of PVC. By reducing the glass transition temperature, they enable products to maintain functionality under various conditions.
- Does Proviron manufacture plasticizers for PVC film?
- Proviron (Germany) commercializes different high-quality non-phthalate plasticizers and bio-based green plasticizers for PVC film applications, general-purpose plasticizer for PVC [www.proviron.com].
- Which plasticizers are used in flexible PVC products?
- The conventional petroleum-derived plasticizers used in many flexible PVC products are phthalate esters (also known as “phthalates”). The literature reported that phthalates represent more than 85% of world plasticizers production, of which 90% is annually used in PVC manufacturing .
