Title: A Review on Plasticizers and Eco-Friendly Bioplasticizers
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887...
Methods for determination of plasticizer migration from polyvinyl
Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those
Green Plasticizers from Liquefied Wood | SpringerLink
The molecular weight and polydispersity index (PDI) of liquefied wood and the synthesized esters were determined by SEC. In addition the LW and the ester plasticizers were analyzed by FTIR and ESI–MS. The average molecular weights and PDI values are shown in Table 1.
Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
Polyvinylchloride (PVC) is a thermoplastic polymer showing low cost and excellent general properties [ 1 ]. PVC is one of the six most commonly used plastics (PE, PP, PS, PVC, PET, and PUR) accounted for 80.2% of the overall demand [ 2 ]. Global polyvinylchloride (PVC) market size was estimated at over 38 million tons in 2015 and is likely to
Plasticizer Migration - an overview | ScienceDirect Topics
This is one example of plasticizer migration. The plasticizer migration rate from PVC to polyethylene decreased when plasticizer polarity increased. For example, DOS is better absorbed by polyethylene than DOP or TCP. Migration rate of plasticizer increases when interaction between polymer and plasticizer decreases.
- Do plasticizers migrate?
- There are several occasions where plasticizer migration can have aesthetic effects. Fogging in glass automotive applications – The plasticizer in an automotive dashboard application outgasses, causing the glass around it to fog up. Paint issues – Migrating plasticizers can damage the finish of the paint.
- How to prevent plasticizer migration?
- Once you understand the level of plasticizers in your materials, you can decide whether or not you need to be doing something about it. There are three main ways you can prevent plasticizer migration. Use specialist plasticizers – Plasticizers with a high molecular weight or a high degree of branching will prevent movement.
- Does a high Tc content affect the migration of plasticizer?
- The activation energy is obviously reduced with the increasing TC content as demonstrated by Zhang and Sun , which further confirms that a high plasticizer content makes migration much easier than low content. Migration of plasticizer is also affected by the molecular size of the plasticizer.
- What affects the migration rate of plasticizer?
- Migration of plasticizer is also affected by the molecular size of the plasticizer. The polymeric plasticizer, dioctyl maleate (DOM), reduces the migration rate (Figure 11.27) . As a high molecular weight, DOM overcomes the resin hardening and minimizes the leaching kinetics.
- How does polyethylene crystallinity affect the migration rate of plasticizer?
- Migration rate of plasticizer increases when interaction between polymer and plasticizer decreases. Also increase in the polyethylene crystallinity degree decreases the migration of plasticizer from external source because sorption and diffusion processes in polymers mainly occur in the amorphous phase.
- Do plasticisers migrate from polymers to a gas phase?
- This paper addresses the kinetics and predictions of plasticiser migration from polymers to a surrounding gas phase, an important issue for plastic and rubber products exposed to high service temperature conditions and during accelerated ageing and testing.
