- the invention also relates to articles which comprise a mixture comprising at least one plastic A, in particular polyvinyl chloride (PVC), polyvinyl butyral (PVB) or a polysulfide, and at least one polyester B which can be prepared from a dicarboxylic acid I and at least one diol II selected from the group consisting of 1,2-propanediol, 1,3-butanediol and 1,4-butanediol and a monocarboxylic acid III.
- PVC polyvinyl chloride
- PVB polyvinyl butyral
- polyester B which can be prepared from a dicarboxylic acid I and at least one diol II selected from the group consisting of 1,2-propanediol, 1,3-butanediol and 1,4-butanediol and a monocarboxylic acid III.
- An object of the invention can, for example, a housing for electrical equipment, a Rolir ein, a device, a cable, a wire sheathing, a window profile, a floor covering, a medical article, a toy, a food packaging, a seal, a sealant, a sealant for Insulating glass, a film, a roof covering film, a composite film, a film for laminated safety glass, in particular for the automotive sector and the architecture sector, a record, synthetic leather, a packaging container, an adhesive tape film, clothing, a coating or a fiber for fabrics.
- PVB articles, in particular PVB films, produced with the mixtures according to the invention are notable for high strength, very good ductility and excellent adhesion to glass surfaces. This enables the production of very flexible films with good transparency and light resistance and very good glass adhesion, which is particularly important for use as films for the production of laminated safety glass.
- the strength and extensibility of PVB films is determined in particular by the Shore hardness A and D (determination according to DIN 53505), the breaking stress (determination according to DIN EN ISO 527, parts 1 and 3), the elongation at break (determination according to DIN EN ISO 527, parts 1 and 3) and the stress at 100%) elongation (determination according to DIN EN ISO 527, parts 1 and 3).
- polysulfide sealants produced with the mixtures according to the invention are not only characterized by high elasticity and low gas permeability, but also by good weather resistance, good chemical resistance, in particular swelling resistance, and good aging resistance.
- the cold-elastic properties of plasticized plastics are preferably characterized with the aid of the cold fracture temperature and the torsional rigidity.
- the cold break temperature is the temperature at which a plasticized plastic shows the first visible damage in the cold under mechanical stress.
- the cold break temperature is determined in accordance with DIN 53372.
- Torsional rigidity is the temperature at which a plasticized plastic can be rotated by a certain angle when a defined force is applied.
- the torsional stiffness is determined in accordance with DIN 53447.
