The world of polyamides is gigantic and its variety enormous: PA6, PA66, PA46, and PA6T are just a few members of the large polyamide family. So why should a compounder like Bada, who already offers all these materials, still admit another new member to the family?

To answer this, one has to take a look at the property profile of this new star in the firmament: Badamid PA9T.

Hygroscopicity: Badamid PA9T with a water absorption of approx. 2% performs better than a polyamide 6 by a factor of four and approaches the value of the low-temperature polyamide PA12. In addition to its excellent dimensional accuracy, this value allows for excellent reflow soldering in the field of electrical engineering even after conditioning. Blistering during lead-free soldering is not an issue with Badamid PA9T components due to the low water content even after prolonged storage. In this context, it is important to emphasize its excellent dyeability and colour stability even after a reflow soldering process. This property makes this material the preferred match for coloured connectors.

Dimensional stability under heat: Near-engine applications are predestined for PA9T due to its high melting point and its glass transition temperature. Compared to PA46, both polyamides have melting points close to 300°C, whereas Badamid PA9T has a glass transition temperature of 125°C, which is more than twice as high. Thus, it shows very constant properties within a high temperature range.

Chemical resistance: Whether fuel, motor oil, liquid saline solutions or alcohols, you will always find our Badamid PA9T at the top of the resistance list compared to other competitive polyamides. Manufacturers of „quick connectors“ for fuel lines recognize the difference and often apply our material.

Did we pique your interest? In addition to the advantages mentioned above, Bada AG has the competence to provide these products readily dyed, so connectors housings and electric components can be produced in your preferred colour, not only in black and white but according to your wishes!

The effectiveness of Bada AG's quality management could be demonstrated again during successful audit by TÜV Rheinland in 2020.

In addition, the current situation in the corona pandemic shows that well-functioning (quality) management offers significant advantages. BADA was able to deal with critical questions at an early stage, took measures to protect employees and prevent corona-related negative impacts and at the same time secure customer supply at all times on the basis of long-standing, good supplier relationships. Bada AG stood and stands by its customers throughout as a reliable and flexible partner.

Established processes allow to respond quickly and flexible to individual wishes and latest developments. The successes achieved by this means encourages all employees at Bada to further develop Bada´s management system and to continuously keep the philosophy of "Quality - Reliability - Flexibility" with the aim of always satisfied customers alive.

If abrasion resistance, chemical resistance, seal effect and highest strain values without tearing are required, TPU is the answer. The benefits of thermoplastic urethanes are beyond doubt and cannot be achieved by other polymers in many respects.

Those who have already processed a soft TPU know that processing and demoulding can be a challenge for both man and machine. Especially with changes in wall thickness and areas that are hard to demould, demoulding can become an art in itself. Remedial measures like blowing out or mould release agents are sometimes of little help.

Working with TPU, changes in wall thickness often lead to sink marks or out-of-round parts. If plane parallelism or concentricity is required, the user may very well despair of the material as high shrinkage and difficult processing of a conventual TPU can be counterproductive.

Here, Bada AG’s new development comes in. A new product group of TPUs filled with newly developed and especially compatibilized glass beads make these grades behave like a conventional TPU in terms of strain values and flexibility. When it comes to moulding, these types are vastly superior to conventional TPU in terms of processing, shrinkage, sink marks and demoulding and all this at an economically more attractive price. In addition, the well-known stickiness of soft TPUs also decreases. Suddenly, tool handles with TPU as handle material are much more comfortable to hold and this with the same chemical and oil resistance.

You will find both the advantages and disadvantages visualized in the attached diagram.

Have we piqued your interest? In addition to the stated advantages, Bada AG has the expertise to supply readily coloured products. Thus, machine handles and components can be processed readily coloured in opaque or translucent colours. Attached you will find a photo of a type in shore hardness 80A with 20% glass beads coloured in several customer-specific colours.

...para estas Fiestas Navideñas y Año Nuevo, les agradecemos sinceramente su inestimable colaboración y nos alegrará enormemente poder continuar desarrollando proyectos comunes en el 2020.
