Bada AG has successively expanded its portfolio of high-temperature polyamides lately and is now ready to provide solutions for all conceivable kinds of requirements.

The product group Badamid PPA-HT was designed for applications at high operating temperatures. Dimensional stability under heat of almost 300°C, exceedingly high rigidity and extremely low water absorptionhygroscopicity are significant properties of these products, which are mainly provided as fiber-reinforced grades. with fibre-reinforcement. Here, filling degreesfiber loadings up to 60% are available. Due to low water absorptionhygroscopicity, constant product properties can be guaranteed throughout the part’s lifespan.

The product class Badamid PPA-GP shows quite similar properties. Compared to Badamid PPA-HT, its dimensional stability under heat is slightly lower and its water absorptionhygroscopicity slightly higher. Its great advantage lies in the processability at mould temperatures below 100°C. This eliminates the need for oil-tempered tools and reduces cycle times in comparison to Badamid PPA-HT.

If the dimensional stability under heat can be slightly reduced and the focus is on good processability and excellent surface quality, Bada offers a series of blends or alloys of aromatic and aliphatic polyamides. Due to the excellent flowability of the compounds, reinforcement degrees of up to 65% and above are possible:

Badamid PPA-HPX shows a similar mechanical and thermal profile as PA66, however, it offers constant properties throughout the part‘s lifespan due to its lower water absorptionhygroscopicity. The special formulation allows PA66-like processing conditions, mould temperatures less than/equal to 100°C and yields parts with particularly good surface quality.

A slight modification of the blend partners results in lower heat resistance for Badamid PPA-HP2X compared to Badamid PPA-HPX. This type’s major advantage is its extremely high weld line strength in complex parts enabled by the above-mentioned modification. Processability and surface quality even top Badamid PPA-HPX.

Badamid PPA-HP is a compromise between dimensional stability under heat and processability. Compared to Badamid PPA-HPX, heat distortion temperature and water absorptionhygroscopicity are slightly higher. Processing and mould temperatures must be set higher here, however, this will result in parts with brilliant surface quality and the aforementioned higher dimensional stability under heat.  

Last but not least, the PPA-Portfolio is completed by Badamid PPA-HP2. Compared to Badamid PPA-HP, a different blend partner yields lower dimensional stability under heat. On the other hand, a particularly high weld line stability can be achieved with PA66-like processing conditions, similar to  PPA-HP2X. The other properties are like those of Badamid PPA-HP.

DieThe Badamid PPA product line is mainly provided with fibre-reinforcement. In addition, further modifications are available upon request, e.g., with flame retardants, impact modification and tailor-made dyeing.

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.
