Know your Plasticizers: A New Study on Plasticizer Migration
In such applications, according to the study, certain plasticizers can cause softening, cracking, or other defects in the non-PVC components as they migrate across the interface between the PVC and the connecting material. In contrast, other plasticizers exhibit little or no effect.
Common Signs Of Plasticizer Migration - Chaffee Industrial
When the plasticizer leaks from a PVC roof, it will cause cracks, splits, and welded sections to break apart. Combining plasticizer migration with foul weather means disaster for your roof. Early spotting of the common signs of plasticizer migration helps protect your roof. Let’s take a look at some of the telltale indicators.
Plasticizer Migration - an overview | ScienceDirect Topics
plasticizer migration to optical fiber coating may result in decreased coating adhesion and possible delamination5. leaching of plasticizer may cause degradation of properties of encapsulated fiber in telecommunication cable 14. when diisooctyl phthalate was used in telecommunication cable strip force was reduced by 90% after 6 months aging at
Methods for determination of plasticizer migration
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
PVC Plasticizer Migration - Chaffee Industrial Roofing
Plasticizer migration occurs as a result of the PVC membrane formulation. Most PVC products, like PVC pipe, PVC trim, and PVC decking, are solid, rigid products. In order to make PVC a flexible membrane sheet, the formulation needs to be altered.
- What happens if a plasticizer migrates?
- Serious migration may result in substantial loss of plasticizer with resultant stiffening of the PVC. An example of plasticizer migration is softening of nitrocellulose or acrylic lacquer following prolonged contact with plasticized PVC.
- What is an example of plasticizer migration?
- An example of plasticizer migration is softening of nitrocellulose or acrylic lacquer following prolonged contact with plasticized PVC. In plasticized PVC film used for tape application, plasticizer migration to the adhesive layer can cause softening and loss of adhesion. 2017, Handbook of Plasticizers (Third Edition) GEORGE WYPYCH, ...
- Can plasticizers migrate from flexible PVC parts to other media?
- An accelerated method has been set up in order to study the capacity of migration of different commercial plasticizers from flexible PVC parts towards other media kept in contact with it; in this case, polystyrene (PS) has been used as example.
- What happens if a plasticizer moves from a PVC item?
- In many applications, the migration of the plasticizer from a PVC item towards the medium in contact with it (gas, liquid or solid) may occur.
- 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.
- How does temperature affect the plasticiser migration process?
- In addition, other ageing processes, such as the oxidation and annealing of polymers, are also accelerated at high temperature. 50 Any effects of these processes on the plasticiser migration process should be determined to yield a correct prediction.
