Description

Decorative panel, and a decorative floor covering made of said panel The present invention relates to panels, in particular to decorative panels, floor panels, ceiling panels, or wall panels. The present invention also relates to a covering comprising a plurality of interconnected panels according to the invention, in particular to a floor covering comprising a plurality of interconnected panels according to the invention. Phthalate esters are widely used as plasticizers for polyvinyl chloride. The alcohols from which plasticizer esters are produced are generally obtained by hydroformylation following olefin oligomerization, or by aldehyde dimerization following the formation of aldehydes through the hydroformylation of olefins, generally via aldol reactions. Therefore, the size and structure of the alkyl groups in the esters vary depending on the process and raw materials used to produce the alcohols. The size and structure of the alkyl groups help determine the volatility and gelation temperature of the plasticizer and are thus selected according to the intended application of the plasticized polyvinyl chloride. There is a continuous need to improve the properties of plasticizers to provide polyvinyl chloride compositions with improved characteristics. There is also a need for alternative plasticizers. Furthermore, there is a need to improve the properties of plasticizers. In particular, it is necessary to minimize the leaching of plasticizers from the main polymer matrix into which they are incorporated by incorporating plasticizers that do not tend to migrate through the polymer matrix. In this context, it is more advantageous when the plasticizer has an eco-friendly profile and is non-toxic.
