Monomeric trimellitate plasticizers have performed very well and are a good choice for buried, flexible PVC geomembranes, especially where sustained high temperatures (greater than 50˚ C) are anticipated. Branched, linear or a blend of monomeric phthalates with a carbon chain

To examine the weatherability of polymeric plasticizers we prepared unfilled PVC compounds containing several polymeric plasticizers and two monomeric diesters, DOP and DIDG

What is PVC geomembrane?
PVC geomembrane is polyvinyl chloride waterproof board. It is a kind of superior quality, high polymer waterproof sheet. By adding plasticizer, anti ultraviolet agent, anti aging agent, stabilizer and other processing aids into PVC resin, through extrusion method to produce molding high polymer waterproof coiled material.
What are PVC-P waterproofing geomembranes?
Formualtion PVC-P waterproofing geomembranes are composed of 30–40% PVC resin and other additives ( Koerner, 2012), mainly plasticizers. Plasticizers are a group of more than 1000 different polymers used to change the behaviour of PVC from a rigid material to a semi-rigid or flexible one.
How much plasticizer is in a geomembrane?
Typically, the plasticizer content in geomembranes ranges from 25 to 35% in weight. Fillers (e.g. CaCO 3) added to the PVC resin may also account for 20–30% of the weight of the geomembrane. Fillers are used to reduce the price, but also to enhance the abrasion resistance and flame-retarding properties.
What is transparent PVC geomembrane?
PVCG-1: Transparent PVC geomembrane. PVC geomembrane is polyvinyl chloride waterproof board. It is a kind of superior quality, high polymer waterproof sheet.
How does a PVC-P geomembrane aging device work?
The device accelerates the ageing of the geomembrane in conditions similar to those in underground applications. Two commercial PVC-P geomembranes are tested, and mechanical tests are performed on the aged geomembranes to evaluate the effect of ageing on the properties of the material.
Are PVC-P geomembranes degraded in underground application conditions?
To analyse the long-term degradation of PVC-P geomembranes in underground application conditions, in this study, a specifically designed accelerated ageing device has been used for the tests. Furthermore, plasticizer absorption tests have been used to estimate the dependence of plasticizer loss on temperature and plasticizer content.
