Thermoplastic elastomers for medical devices

Biocompatible ProvaMed® TPE compounds meet the highest standards of purity, cleanliness and hygiene

Together with our partner, Actega, we offer a broad range of premium thermoplastic elastomers (TPEs) for medical applications such as breathing masks, ventilation tubes and IV sets.

 

The materials used to produce the ProvaMed granules comply with the requirements of the European Pharmacopoeia or have been examined according to generally accepted standards for their biocompatibility. The ProvaMed TPE range is suitable for sensitive applications on the basis of a conclusive study in accordance with ISO 10993 and USP Class VI.

 

Great flexibility – endless possible applications

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. allow the compounds to be used for e.g. manufacture of film and bags for IV applications and 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 makes ProvaMed materials well-suited for use as a base material for handles, control elements, or keypads, where 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 mean 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, allow 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.
