DESCRIPTION:
Drapex 39 is an epoxidized soy bean oil.
Drapex 39 is used as a non-toxic co-stabiliser in rigid and plasticised PVC and other chlorine containing polymers.
Drapex 39 offers improved weatherability.
CAS NUMBER: 8013-07-8
EC NUMBER: 232-391-0
MOLECULAR FORMULA: C57H98O12
MOLECULAR WEIGHT: 975.4
DESCRIPTION:
Drapex 39 is used in calcium/zinc stabilized rigid PVC with the most stringent organoleptical requirements.
In mineral water with low carbon dioxide content the packaging material has an organoleptical influence on the contents of the container.
Drapex 39 has been especially developed to avoid this problem.
Drapex 39 plasticizers are manufactured from renewable feedstock and effectively serve as both secondary plasticizers and co-stabilizers in nearly all PVC systems.
Drapex 39 is slightly yellowish, medium viscosity liquid.
Drapex 39 is a non-toxic co-stabiliser used in rigid (based on calcium/zinc stabilisers) and plasticised PVC (stabilised with metal soaps) and other chlorine containing polymers.
Drapex 39 markedly improves the weatherability of PVC articles and acts as internal lubricant and plasticiser.
Drapex 39 is a non-toxic co-stabilizer used in rigid and plasticized PVC and other chlorinated polymers.
The stabilizing effect of Drapex 39 is based on its ability to “bind” hydrogen chloride.
As a co-stabilizer for organotin or metal soaps, Drapex 39 has a positive effect on long-term thermal stability.
In addition, Drapex 39 significantly improves the weather resistance of PVC products.
As a fatty acid ester of Drapex 39 , it also acts as an internal lubricant and softener.
The concentration must be adapted to the formulation according to the expected effect.
In general, Drapex 39 cannot be used only as a single plasticizer, for a good result the amount of plasticizer should be 10 - 15%.
When processing rigid PVC, Drapex 39 is used as a co-stabilizing internal lubricant.
Drapex 39 is particularly important in the production of non-toxic rigid PVC based on calcium/zinc stabilizer.
Only such stabilization provides adequate stabilization of rigid PVC compounds on equipment such as calenders and extrusion blow molding machines.
Drapex 39 is an organoleptically improved modification of Drapex 39.
