What are TPEs?
The material class of thermoplastic elastomers (TPEs) is characterized, on the one hand, by the classic properties of an elastomer (elasticity, high thermal and chemical resistance, etc.) and the ease of processing of a thermoplastic, on the other. Elastomeric materials, such as crosslinked EPDM or natural rubber, cannot be melted by the addition of heat and are therefore very costly to process. Thermoplastic elastomers can be melted because they are not crosslinked chemically (but, instead, physically) and thus brought into the desired shape when heat is applied.
*Our plastics can be dyed practically any color due to the addition of color masterbatches. Just let us know what you need!
Thermoplastic elastomers combine the properties of both families of compounds. The physical crosslinking of the synthetic polymer chains means that an elastomer-like property profile is created. As these crosslinks are reversible, however, they can be reformed by heat, thereby enabling the plastic to be melted.
The chart above offers an insight into the variety of the thermoplastic elastomers available. The property profile can be flexibly formulated within a broad frame; so, should you be looking for a plastic with special mechanical properties, just get in touch with us.
The ProvaMed product range meets the highest standards of purity, cleanliness, and hygiene. Thanks to our many years of experience with producing plastic granules for exacting and regulated fields of application, we are able to provide premium plastics of excellent quality.
Materials are used to produce the ProvaMed granules that comply with the requirements of the European Pharmacopoeia or have been examined according to generally accepted standards for their biocompatibility. We confirm that our plastics are suitable for sensitive applications on the basis of a conclusive study in accordance with ISO 10993 and USP Class VI. We would be happy to supply you with the relevant documentation.

The variety and flexibility of the ProvaMed materials opens up a virtually limitless area of possible applications. The special composition and choice of materials used in line with regulatory and technical standards enables the material properties to be adapted quickly and safely to the individual requirements of the particular application.
Properties such as hardness, elasticity, chemical resistance, gas permeability, etc. permit ProvaMed Compounds to be used, for example, to manufacture film and bags for IV applications or to produce tubes and components through which sterile solutions or bodily fluids can be transported. No loss of mechanical properties even with constant exposure to the medium in question further permits ProvaMed materials to be used as closures for liquid and solid pharmaceuticals. The permanent elasticity and outstanding sealing properties guarantee safe use as a stopper, septum, or cap gasket.
The specific adjustment of the surface properties allows ProvaMed materials to be used as a base material for handles, control elements, or keypads. Here, excellent feel and slip resistance distinguish the materials for the most part. Both improvement to the haptic properties of a product and the incorporation of design elements, therefore, become a real possibility.
ProvaMed’s highly elastic properties, excellent barrier effect, and flexibility means that it can be used in place of silicone-based materials to manufacture such items as sealing rings. Here, the thermoplastic processing of ProvaMed TPEs reveals their advantages in the reduction of cycle times and simplification of manufacture.
Excellent adhesion to plastics such as polypropylene, polycarbonate, or ABS permit so-called "hard-soft combinations" to be produced. Here, a hard and rigid base material is partially overmolded with soft elements made from TPE to obtain a smooth and non-slip surface structure. A wide variety of design ideas are thus possible in the fabrication of handles for surgical instruments, the manufacture of orthopedic aids (walking frames, etc.), or the design of personal hygiene products. The suitability of ProvaMed TPEs for contact with foodstuffs as well as their toxicological harmlessness allows products to be manufactured quickly with minimal regulatory effort.
