PostHeaderIcon Research and Development

Research and development of these products almost does not exist, for example oils: Linseed, Castor, Rape, Soybean, etc., known since antiquity, over time, has almost completed its knowledge and applications.

Thus, they have gone through different stages as food products (seeds), medicinal / cosmetic (for pressing oil), soap base (being triglycerides), for drying oil coatings (due to triglycerides with double bonds), manufacture of polyurethanes (for the OH group), edible oils, etc.

With reference to plasticizers. In 1930 B.F. Goodrich discovered that PVC absorbs a product that is called plasticizer and when prossing it becomes flexible PVC. That was Octyl Phthalate plasticizer, from here other plasticizers were developed, with a molecular weight of 300 and a spacial  large volume, doing like a mattress between the PVC molecules, giving flexibility .

PVC is a thermoplastic polymer, indicating that can be moulded in a reversible way , without losing their chemical, physical and mechanical properties.

Thus appeared the family of phthalate DOP, DINP, DIBP, DBP, DEHP, and so on. The most widely used due to their quotation, but impermanent.

Family esters. Adipates DOA, DIDA, trimellitate BMT, TMC8-C10, TMC7-C9, citrates, called monomeric plasticizers. They can be regarded as more specific plasticisers, to adapt to situations application.

Family of epoxidized. Epoxidized Soybean Oil, epoxiesteres, etc.., Secondary plasticizers, inhibitors, thermal degradation and the generation of acid hydrolysis,  They may also be called additional plasticizers.

Family polyesters, polymeric plasticizers called Adilens or permanent.

Other families. Phosphates, Benzoates, Sebacates, etc..

 

The research would be to develop the "optimal mix of plasticizers" for each particular application, to control different variables of interest for us: volatility, migration, extraction, temperature, viscosity, lubrication, etc.

Traquisa / University

Traquisa long ago has maintained a very cordial relationship with University, as is the way to keep up to date research for the optimization versus plasticizers application.

This collaboration is shown in an attached study by the University of Valencia and Traquisa.

The effect of the curing time and temperature on final properties of flexible PVC with an epoxidized fatty acid ester (Plastificante 401) as natural-based plasticizer (febrero de 2009)
