Have you noticed stress cracking in polycarbonate parts that contact flexible PVC for prolonged periods? As it so happens, this doesn’t only happen to polycarbonate. Other commonly used
For many years PVC tubing compounders were using conventional phthalate plasticizers. In recent years, there has been an increased awareness of a phenomenon called “plasticizer

Environmental stress cracking (ESC) (failure caused by crack and craze formation at a stress less than the yield stress) reduces the service life of many plastic products. This paper is concerned with ESC of rigid PVC products
DSC studies showed that a blend of PVC with furan dicarboxylates reacted with 1-butanol exhibited similar T g values as PVC/DOP, especially when the plasticizer content was higher than 42,9 phr. T g values of plasticizers with

Polyvinyl chloride (PVC) is polymerized from vinyl chloride monomers and is one of the commonly used thermoplastic. Strength and modulus of PVC are the most excellent
cracking. A new stress field is created at the crack tip and the process continues. Source: Adapted from D.C. Wright and Jansen [12, 14] Figure 3. Environmental Stress Cracking

10,000-25,000 cps did not cause stress-cracking to polycarbonate. There are factors other than viscosity that can also effect the stress-cracking problem. Plasticizer chemical type, level of

- Does polycarbonate crack when in contact with PVC plasticized?
- no evidence to stress-cracking when in contact with PVC plasticized by the P S-160,000 polyester. The compound containing PeS-5,000 induces minimal cracking to polycarbonate.The visible signs of stress- ack development in polycarbonate are one way of evaluating performance in a specific environment. Polycarbonate has a high degree of elo
- Can polymer plasticizer improve thermal stability of PVC materials?
- Both the high and lower branching of polyester plasticizer can improve thermal stability of PVC materials compared to DEHP. Hyperbranched poly (ε-caprolactone) (PCL) with different lengths of linear segments and different numbers of branches, as the polymer plasticizers, show no migration in volatility, extractability, and exudation tests .
- Why do flexible PVC products need plasticizers?
- The properties of flexible PVC products significantly change with addition of plasticizers, such as reduction of the glass transition temperature (Tg) and tensile strength, while elongation will increase, which make PVC change from hard and brittle to flexible, thus greatly expand its application [, , ].
- Can polymer plasticizer extend the life of PVC-membrane ion-selective electrodes?
- Polymeric plasticizer, such as poly (butylene sebacate), can extend the life time of PVC-membrane ion-selective electrodes and keep their property long stable [84, 85]. PBA with molecular weights ranging from 2000 to 10000 g/mol and PVC is not completely compatible and forms a semimiscible two-phase system.
- Which triester is a stress-inducing plasticizer?
- exyl azelate (DOZ) and diisodecyl glutarate (DIDG) cause severe stress-cracking to polycarbonate. A triester, tri-2-ethylhexyl trimellitate (TOTM), was also evaluated and found to provide slig t improvement over diesters, but still considered to be an aggressive stress-inducing plasticizer.
- Does polyester plasticizer reduce migration resistance?
- High degree of branching of polyester plasticizer more effective to reduce migration resistance than low degree of branching of polyester plasticizer. Both the high and lower branching of polyester plasticizer can improve thermal stability of PVC materials compared to DEHP.
