Cellasto® - where creativity meets performance
Cellasto® - where creativity meets performance
When you work with our team, you have access to a large portfolio of materials with varying capabilities. This includes Cellasto®, a dynamic, resilient material available in a range of grades to suit multiple purposes and budgets.
A fully certified Tier 1 supplier for both industry and automotive customers, when you work with BASF Cellasto®, you get more than just materials. You gain a complete engineering package and the quick development, innovative testing and quality standards that come with it, including:
Cellasto® is a microcellular polyurethane elastomer that provides superior noise, vibration and harshness (NVH) reduction compared to rubber, plastic and other elastomers and is used in a wide range of applications and industries.
In automotive and independent aftermarket applications, this dynamic polyurethane foam’s high compressibility with low lateral expansion results in smaller, lightweight components.
The outstanding abrasion and environmental resistance of Cellasto® — including ozone and temperature — allow innovators to produce dynamic, durable components while maintaining a high level of design freedom.
We offer this unique material in a range of grades to suit different budgets and purposes, from premium to economy. We even offer compact, non-foam material solutions for components, such as subframe mounts. This material still allows you to reap some of the benefits of a microcellular polyurethane, including improved NVH performance and abrasion resistance.
We currently have five testing sites worldwide with a broad range of load and frequency testing capabilities. Since prototypes are expensive, testing “on the bench” is key to avoiding costly mistakes. Our rigs can test the entire automotive system, from bumper to coil spring isolator.
Our machines are also capable of translating customer data into testing, such as the profile of road, force level, and accelerations, creating a quicker, more accurate loop of development.
This initial test involves the slow deformation of the component through pressing, allowing OEM engineers to see the load-deflection curve (CLD).
From a drop height of up to 1 meter, we use drop testing to check the durability of the component.
This important durability and dynamic performance test is used to determine the lifetime of the automotive parts. This machine’s flexibility enables OEMs to define their own tests, including the shape and interruption of each movement. This test is appropriate if you need to determine the necessary load and amplitude in displacement as well as velocity.
This test is also ideal for electric cars or other vehicles with bumpers mounted to components other than the shock absorber, resulting in a dynamic movement rather than a linear one.
The hydropulser is particularly applicable to polyurethane testing, which counterbalances the unique properties of the material that make accelerated tests difficult to perform. Not only that, but our software is proprietary, which means we can upgrade or make changes quickly.
As a result, parts for your electric cars and other vehicles containing our polyurethane foam can undergo testing that provides accurate results.
High-Frequency Test Rig
With a high frequency of 4000 Hz, this machine is ideal for testing the dynamic behavior of the bushings between the engine and the body when trying to reduce noise in the passenger cabin.
With more than 25 years of experience in application and theory, simulation is an integral part of our development process and is part of our digital competencies.
Our expertise is particularly strong in material mechanics and microcellular polyurethanes (MCU) modeling, as well as structural analysis through non-linear FEA (Finite Element Analysis).
Our technology, combined with the expertise of our CAE analysts, ensures that simulation serves to benefit the entire development process, resulting in Cellasto® products designed by BASF for high-performance applications.
Using our research as well as leading software packages for non-linear FEA, BASF has developed advanced methodologies tailored to the specific needs of Cellasto® and its wide range of applications.
Our simulation process accelerates the development phases by reducing the number of physical prototypes and amount of testing. In some cases, development cycles can even be skipped, enabling us to respond more quickly to our customers.
By using our FEA simulation methodologies in structural analysis, our CAE analysts can provide valuable information for Cellasto® product design, such as:
analysis of deformation behavior, including stability, contact and collision
load-deflection-characteristic and stiffness
stress/strain-analysis for assessment of local material loading and strength
reaction forces on assembled parts
Since proof of concept is possible without real prototypes, the BASF team can focus on product performance and quality from the start. Within virtual design loops, we can adopt and optimize product design to best fulfill your requirements.
Our methodology even outperforms classical design methods due to its ability to provide insight that is not available by means of any other experimental technique, such as with physical tests that would be too large or too complex to be realized within the confines of a test lab.
