Thermoplastic Elastomers (TPEs) combine the properties of a thermoplastic with those of a synthetic rubber. Available as a film or in sheets, some key benefits of TPEs produced by Vreeberg BV include a soft and flexible feel, elasticity, a latex and PVC-free composition, and easy adhesion to a wide range of plastics. Vreeberg’s latest development is a fabric covered elastic sheet.
TPEs consist of styrene block copolymers. This is an exceptional basic starting material because a molecule of block copolymers combines the properties of a thermoplastic with those of rubber. This produces a unique type of polymer in which two hard, rigid end-blocks are connected with each other by a flexible, elastic mid-block. TPEs are easy to colour: fluorescent, metallic and pearl effect and glow in the dark are available options.
When resistance against UV and Ozone influence is necessary for the use of this material outdoors, its properties can be adapted. Vreeberg can also offer specific resistance against extreme heat or cold and chemicals on demand. Additionally, by variation in the composition of the compound, a wide variety of medical applications are possible, such as bed covers and materials for blood bags. These TPE’s are particularly well suited for hospital environments as, unlike natural rubber, they do not aggravate latex allergies.
Vreeberg supplies film and sheet in any elastic material. Thicknesses start from 0,1 mm to 4 mm, and widths from 1 to 1200 mm. TPE sheets and films can be easily welded, also to PE or PP material. This makes the use of glue or tape unnecessary. Vreeberg’s latest development is the production of fabric covered elastic sheet. During extrusion, the fabric is indissolubly attached to the TPE sheet, on one or two sides.
