For PVC, primarily in vinyl plastisols, Viplex 895 is used at 70% replacement levels of phthalate plasticizers. For polyurethane systems, Vycel U is used as an extender, has superior compatibility, and is free of HAPs and noncarcinogenic. Viplex 530-A is used in industrial foams at up to 60% replacement levels.
POE Alloys Replace Liquid Plasticizers In High-Performance
Flexible PVC formulated with the new PVC/POE alloy, with or without liquid plasticizer, is expected to be only 10% to 15% more expensive than conventional PVC, says Teknor's Morin. However, all the POE/PVC alloys have lower specific gravity than conventional PVC, which improves their economics.

POE Alloys Replace Liquid Plasticizers In High-Performance. Developmental Alloy 1 in the table, containing 20% compatibilized POE and 60 phr of DEHP plasticizer, achieves a Shore A hardness of 70. Surprisingly, the brittle point of Alloy 1 actually drops 20° C after seven days of oven aging at 121 C. Likewise Alloy 2 (25% to 35% POE, 20 phr ..

POE Alloys Replace Liquid Plasticizers In High-Performance. No liquid plasticizer. Test results on an array of PVC compounds containing 20% to 35% POE and 0 to 60 phr of liquid plasticizer were presented by Vishal Kadakia, product-development engineer, at the Society of Plastics Engineers' Vinyltec 2001 conference in Iselin, N.J., last September.
- Does a mixture of Plasticizers improve the mechanical properties of PVC?
- Moreover, the mechanical properties were improved when a mixture of plasticizers was applied in PVC blends, whereas a blend with pure SOHE showed worse mechanical properties (lower elongation at break and higher tensile strength) than DOP.
- Can plasticizers be replaced by new compounds?
- This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency. ...
- Why are new plasticizers a problem?
- The main problem in developing new plasticizers is to find a compound providing good mechanical properties to PVC, but with limited migration, extraction resistance and low volatility. There are a lot of studies describing novel plasticizers that exhibit excellent migration resistance at the expense of the deterioration of mechanical properties.
- Why do plasticizers whose molecular weight and degree of branching are too high?
- Plasticizers whose molecular weight and degree of branching were too high exhibited worse plasticization properties because of limitation in PVC backbone mobility due to the specific interactions between the carbonyl groups of the polymeric plasticizer and the chlorine groups of the PVC chain.
- Is PVC a good plasticizer?
- Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
- Which plasticizer blend has the best tensile properties?
- The DA-8 plasticizer blend with PVC presented the best tensile properties in comparison with DOTP: comparable elongation at break and tensile strength. A volatility test showed lower weight loss of the new plasticizers than those observed for DOTP, which is obvious due to the higher molecular weight of those novel plasticizers.
