CASE STUDIES
TPE solutions for seatbelt
tensioners.
One of our clients in the automotive market was using Thermoplastic Vulcanizate (TPV) compounds in seatbelt tensioners. However, the TPV compounds they were using had issues related to cost, appearance, and performance. The suppliers of this material were unable to meet the required color specifications, which posed an additional problem for the client, as it impacted the financial results of this product line.
For this reason, the client turned to Alphagary Compounds and requested the development of a solution using TPE (Thermoplastic Elastomer) compounds that would meet the cost and performance requirements, along with the following improvements:
Wider processing window
- Consistent natural color
- Reduced cycle times
- Non-hygroscopic
- Improved surface appearance
- Cost savings compared to TPV compound
- Shorter lead time
Problem
The client was experiencing color inconsistencies when using TPV, making it difficult to maintain color stability in the parts processed through injection molding.
Para sobrepasar esta dificultad, el cliente enviaba el TPV natural a una empresa de compuestos de colores para pigmentarlo del color que requería. Sin embargo, esta empresa ofrecía únicamente largos tiempos de entrega que presentaban retrasos y costos adicionales.

Application
Seatbelt tensioners.
Challenges
At Alphagary Compounds, we offered the client the development of a TPE compound to replace the TPV products they were using.
The new TPE compound offers several advantages. On one hand, it extends the processing window; on the other, it reduces cycle times and is 100% recyclable.
Además, el TPE tiene un color natural consistente, por lo que el cliente puede añadirle los pigmentos deseados a la hora de hacer el moldeo por inyección. Esto disminuye el tiempo para desarrollar colores personalizados y los costos que esto conlleva. Finalmente, nuestro compuesto al ser no higroscópico, no necesita tiempo de secado.
