Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Structure‐Performance Guided Design of Sustainable Plasticizers
Traditionally, ortho-phthalates have represented the most important and well-known product class of plasticizers. However, some of these molecules are now subject to restrictions and authorization by the EU's REACH legislation (Regulation (EC) No. 1907/2006) due to their toxicological profile, and by now have mostly been replaced. 6 For so-called low molecular weight phthalates (LMW) like di(2
Selecting Heat Stabilizers for PVC
Epoxy plasticizers (epoxidized soybean, linseed oils and tallate esters) are often used in PVC compounds as an auxillary co-stabilizer with mixed metal stabilizer systems. Functioning as HCl acceptors primarily, epoxy Plasticizers enhance the heat and light stability of most mixed metal/phosphite stabilized compounds.
Plasticizer - an overview | ScienceDirect Topics
Good plasticization involves interspersing plasticizer molecules between PVC chains, breaking the small amount of native PVC crystallinity, and internally lubricating the polymer blend. While there is no formal chemical bond between plasticizer and polymer, the polar attraction between them makes plasticized PVC more than a simple physical mixture.
A Strategy for Nonmigrating Highly Plasticized PVC
Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di(2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as
- What are the best value-added PVC plasticizer options?
- Let’s now turn our attention to three value-added PVC plasticizer options that exceed the emerging requirements of REACH and European Union (EU) regulation. VESTINOL® 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window.
- What is a stabilizer in PVC plastic?
- Stabilizers are a key central additive in PVC plastic formulations. Flexible PVC materials are built upon liquid mixed metal soaps that are the most commonly used stabilizers.
- What are plasticizers used for?
- Mainly used for PVC, plasticizers improve the flexibility and durability of plastic end products. They also act as softeners, extenders and lubricants. SONGWON offers a comprehensive range of PVC stabilizers and plasticizers. In our PVC application lab in Ulsan, Korea, we support customers with expert formulation and performance evaluations.
- Which plasticizer blend has the best tensile properties?
- The DA-8 plasticizer blend with PVC presented the best tensile properties in comparison with DOTP: comparable elongation at break and tensile strength. A volatility test showed lower weight loss of the new plasticizers than those observed for DOTP, which is obvious due to the higher molecular weight of those novel plasticizers.
- Which plasticizer is the best?
- BASF’s Palatinol® DOTP plasticizer has a GreenScreen low toxicity rating. Hexamoll® DINCH also has a substantial sustainability plasticizer grading. Alternatives to traditionally used DEHP (DiEthylHexylPhthalate) plasticizer are always of interest in the highly regulated medical plastic devices and broader healthcare applications.
- Do Plasticizers improve mechanical properties of poly(vinyl chloride)?
- Conclusions This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency. ...
