Estalene EN is a compounds range formulated to be used for the injection or extrusion molding of synthetic corks and it is made without SIS, SBS, SEBS rubbers. Estalene EN is patented by Cossa Polimeri. The elastic behavior of Estalene EN is obtained with a belnd of modified polyolefins. The product is studied in order to imitate the aspects of natural cork also in its superficial defects. To have the best performances we suggest the use of Estalene EN matched with an expanding agent (i.e. Estafoam 13 STO) that allows to obtain cells extrememly compact and very well distributed. The cork made of Estalene EN are equivalent to the traditional ones, concerning weight, functional and aesthetic aspects. The raw material used to produce Estalene EN are suitable for food contact. Estalene EN is certified according to FDA standards.&& |
