Iodine Value | Max 3.0% |
Epoxy Value | Min > 6.2% |
REACH and RoHS compliant; high purity verified; ISO 9001:2015 certified production.
Low volatility prevents plasticizer loss during processing and service, keeping films flexible and dimensionally stable over time.
No, this grade maintains excellent clarity and low color, suitable for transparent film applications.
Yes, the epoxy groups in ESBO act as HCl scavengers and co-stabilizers, reducing degradation at processing temperatures.
Typical dosage is 3-8 phr as a co-plasticizer/stabilizer; higher loadings may be used where plasticizing effect is required.
