Incorporation of a renewable plasticizer into PVC compounds
In this report, we describe a comparative analysis of the biodegradation of PVC compounds containing a renewable vegetable-derived plasticizer (RVP) with ester structure of corn and molar mass 296.5 g.mol - 1, or one of two synthetic plasticizers (dioctyl phthalate - DOP and dioctyl adipate - DOA). FTIR showed a greater interaction of RVP with
A sustainable poly(vinyl chloride) plasticizer derivated
Poly(vinyl chloride) (PVC) is one of the most widely used plastics for numerous applications. Generally, pure PVC has a high glass transition temperature (T g) and low thermal stability. Therefore, a plasticizer is commonly added into PVC during processing in an effort to increase its stability, flexibility and workability [Bocque et al., 2016
Mechanical properties of renewable plasticizer
As it was known to us, the bands around 1745.9 and 682.7 cm −1 were attributed to the C O of plasticizer and C H of PVC, respectively . After incorporation of the plasticizers into the formulations, the absorption frequencies of carbonyl group can be shifted to frequencies of lower wave numbers (lower energy).
Plasticizer Effects in the PVC Membrane of the Dibasic
The PVC-based membrane of this sensor was not optimized and further work was necessary to improve its performance. Four areas of investigation were necessary: the plasticizer used in the PVC membrane, the amount of ionophore to be incorporated, the type of support polymer, and the inclusion of ion exchange sites in the form of lipophilic salts.
Green Plasticizers for PVC - Advances in Engineering
During processing of polymers, such as polyvinyl chloride (PVC), phthalate esters are often used as the main plasticizer. Recent researches have established that phthalate plasticizers have a tendency to migrate from a polymer matrix into which it has been incorporated, into the natural environment.
A brief overview of theories of PVC plasticization
This paper reviews the most widely used models for explaining how plasticizers render PVC flexible. These models include the gel, lubricity, and free volume theories; kinetic theories; and mathematical models which predict on the basis of plasticizer structure how much a plasticizer will lower the polymer glass transition in a flexible PVC compound.
Developments in bio based plasticizers, PVC Compounds, Wire
Olvex 51 Biobased Plasticizer for PVC has been developed by Brazil s SGS Pol meros. Olvex 51 is a bio-based, renewable primary plasticizer produced from vegetable raw materials and renewables which is used as a substitute for petroleum-based plasticizers (DOA, DOP/DEHP, etc) replacing it in 100% and used in traditional PVC, PLA.
New biobased PVC compounds for FDA applications - bioplastics
Formulated from renewable feedstock, Sylvin’s new 39 series compounds are formulated with a plant-based plasticizer rather than traditional petroleum-based plasticizers such as phthalates. The 39 series incorporates only ingredients that are sanctioned for use by the FDA and the compounds have the same feel, flexibility and ease of processing
DOW ECOLIBRIUM bio-based plasticizers | AIChE
DOW ECOLIBRIUM bio-based plasticizers are designed to be incorporated into polyvinyl chloride (PVC) compounds used to make wire insulation and jacketing. They are made of 100% renewable feedstocks and can help cable manufacturers and original equipment manufacturers (OEMs) to reduce greenhouse gas emissions by 40% when used as a replacement for traditional PVC plasticizers.
How to Solve the Biggest Floor Compatibility Problem
Plasticizer migration happens when the PVC found in some flooring tiles or backings reacts with adhesive left over from previous installations. Plasticizer migration can cause flooring tiles to discolor, soften, or in the worst-case scenario, slide around as the adhesives dissolve into an oozing mess and stop holding the floor tiles in place.
Effect of Palm Oil Bio-Based Plasticizer on the Morphological
co-plasticizer to di-octyl phthalate (DOP) and di-isononyl phthalate (DiNP). The effects of the incorporation of the palm oil-based alkyd on morphological, thermal and mechanical properties of PVC compounds were studied. Results showed the incorporation of the alkyd enhanced the mechanical and thermal properties of the PVC compounds.
NOVEL FLEXIBLE PVC COMPOUNDS CHARACTERIZED BY IMPROVED
1 part per million. The product of the polymerization process is unmodified PVC. Before PVC can be made into final products, it almost always requires conversion into a compound by the incorporation of additives. 1.4 The K value n
