Thermal stability of poly(vinyl chloride) with epoxidised
Epoxidised soybean oil (ESBO) has been tested as a primary plasticizer in suspension PVC. The stabilization of the material with different traditional stabilizers has been evaluated and compared to a compound with PVC–ESBO only. Surprisingly, the addition of stabilizers seems to decrease the stability of PVC–ESBO.
UV and thermal stability of soft PVC plasticized with
In particular, the value of A NT for samples m5 and m20 is even lower than that measured for ESBO, which is usually considered as an efficient stabilizer for PVC. Therefore, PLACARD plays both roles in soft PVC, plasticizer and thermal and UV stabilizer, limiting the oxidation of PVC. Download : Download high-res image (108KB)
CONTRIBUTION OF EPOXIDIZED SOYBEAN OIL IN PVC
Processing advantages: Epoxy compounds contribute to heat stabilization through two reactions. 1. Neutralization of HCl. 2. Substitution of Labile chlorine. The Epoxide ring from ESBO reacts with
