ProvaMed® TPE 

TPE compounds for medical technology

What is ProvaMed®?

Our TPEs for medical and pharmaceutical applications are summarized under the ProvaMed® brand. ProvaMed® stands for soft-elastic TPEs complying with the highest demands on purity, hygiene and safety. We bundle our portfolio of standard products for medical technology under ProvaMed® as well as our development and production competence for customized, tailored TPEs for highly-sensitive areas of application. Our ProvaMed® TPEs display a Shore hardness range of A-20 to A-90.

How can you benefit by using ProvaMed® TPEs?

The fact that our ProvaMed® TPEs are free of PVC and plasticizers means that you can lend your products an exemplary function while simultaneously protecting patients and specialist medical personnel.

You gain extra freedom of design, flexibility and sustainability when you combine components made from soft PVC with those made from TPEs with customary solvents or process them in an economic multi-component injection-molding process which is easily possible with our solvent-bondable and adhesion-optimized TPEs. On the one hand, they reduce the percentage of harmful PVC plastics containing plasticizers in your products, thereby avoiding the pervasive debate about plasticizers. On the other hand, you can work significantly more economically as the multi-component method shortens cycle times and reduces the effort involved in assembly.

You can design the time-consuming process of qualification of your medical product significantly less stressfully by using ProvaMed® TPEs which have already been tested in accordance with ISO 10993-5 with outstanding results. How you can achieve faster and more successful market access for your new product plans when collaborating with our experts in the area of TPEs: they support you throughout, from development through to market launch. And they can also guarantee 100% material supplies: at all times, anywhere and anytime. This is of decisive importance for your medical products in particular which are applied in situations where every second counts.

We would be delighted to advise you on the use of ProvaMed® and the individual advantages for you. Please contact us!


What can ProvaMed® be used for?

The possibilities are manifold as the TPEs can be easily processed in extrusion, injection-molding, and multi-component injection-molding methods. We would like to present some examples here which highlight the particular advantages of our TPEs over other materials, e.g. for drip chambers, medical tubes such as multi-layer and co-extrusion tubes, pharmaceutical plugs or syringe piston seals, as certain property profiles of our TPEs, including particularly good adhesion to thermoplastics such as PE, PP, PS, ABS, PC and PA, which are also retained even in the case of continuous contact with media and increased temperatures, ensure high product benefits here.

TPE solutions for pharmaceutical stoppers

The TPE compounds specially developed for pharmaceutical stoppers and medical closures enable an economically attractive solution in terms of processing, function and safety. The TPE materials for pharmaceutical stoppers fulfill all the regulatory functions required by USP 381, such as resealability after puncturing with a cannula. Compared to the conventionally used materials, the TPE product solutions for pharmaceutical stoppers are recyclable and convince with easy processability by injection molding and with short cycle times.

TPE solutions for medical drip chambers

We offer highly-transparent TPEs for drip chambers and tubes in order to guarantee the optical control of the drip process and fluid level. Furthermore, we have optimized our TPEs so that they can be bonded with standard solvents, e.g. the tube with the drip chamber. At the same time, our ProvaMed® TPEs are distinguished by their flexibility, rigidity, and recovery capability. And of course by the fact that they are free of PVC and plasticizers.

TPE solutions for two- / multi-component injection-molding

As a general rule, our TPEs can be processed in economical two-/multi-component injection-molding as the products display perfect adhesion to polystyrene and ABS. For example, multi-component hard/soft compounds are possible in applications comprising TPEs and ABS, PC or PP. Such adhesion-optimized TPEs enable you to achieve shorter cycle times while reducing the efforts associated with assembly.

But what exactly are TPEs?

TPEs are between thermoplastics (plastics such as PP, PE or PVC) and elastomers (rubber types). They combine the easy processability of thermoplastics with the essential properties of rubber. Unlike viscoelastic rubber, natural or synthetic rubber which only decomposes through great heat after vulcanization, the chemical cross-linking of individual molecule chains, but cannot be remolded, thermoplastic elastomers become moldable again through heat (thermos) and elastic after cooling. In contrast to chemical cross-linking, this involves a physical process which can be reversed by the renewed addition of heat.

There are a variety of thermoplastic elastomers. The most important role is played here by the group of styrene block copolymers (TPE-S). This group accounts for around two-thirds of TPEs used in Western Europe. TPE-S materials offer some interesting possibilities thanks to their flexibility. The advantages of these TPE-S materials are based on sophisticated formulations comprising many different components. Using these TPE-S materials, we can supply a variety of standard products as well as offering customized solutions.
