Sandler Nonwoven Properties: Quality that creates Trust
Whether it's filters in the food industry, medical nonwovens, or sustainable solutions in the mobility sector - modern nonwovens are instrumental in many applications. We frequently benefit from nonwovens without even taking notice: in vehicles, buildings, filtration systems, indoor spaces, or technical applications. Nonwovens filter, absorb, insulate, protect, or contribute to our comfort and efficiency.
Especially in sensitive applications, the interplay of material, function, and application is vital for the performance of a nonwoven. The properties of nonwovens are being purposefully designed, depending on the raw material, the process, and the requirements the material has to fulfil.
Which products does Sandler produce? And which solutions does Sandler develop - from bluefiber to polyniq® and finexus®?
Sandler develops and manufactures nonwovens for numerous industries and applications, such as mobility, industry, hygiene, household, and construction as well as solutions for insulating, filtering, padding, cleaning, and protecting.
This range demonstrates the versatility of the properties of nonwoven materials. Depending on the application, nonwovens can dampen noise, insulate against heat or cold, filter particles, absorb humidity, protect surfaces, or balance mechanical stress. At the same time, the efficient use of resources, recyclability, and circular economy are becoming increasingly important.
Specialized solutions such as bluefiber, polyniq®, and finexus® prove Sandler's ability to translate material competence into specific applications: bluefiber is a nonwoven solution for indoor acoustics, polyniq® is a development approach for filter solution for hygiene and medical applications, and finexus®: a mono-material solution for state-of-the-art mobility. Each of these brands brings together specific material properties with the requirements of the respective applications.
Are Sandler filter media suitable for applications in the food industry or in medical environments?
Sandler nonwovens are suitable for food contact as well as for medical applications with a focus on sterility and purity.
We can purposefully adjust selected materials to various applications, always keeping the specific technical and regulatory requirements of the intended application in mind.
Nonwovens under the polyniq® brand are the essence of Sandler's material competence in the field of filtration applications in hygiene and medical settings. polyniq® nonwovens bring together defined material properties (based on specialty polymers) with the requirements of sensitive applications and represent solutions that focus on purity, comfort and functionality.
Likewise, bluefiber and finexus® are based on an application-oriented development approach. While polyniq® was developed for filtration applications in hygiene and medical settings, bluefiber and finexus address the specific insulation requirements of the construction and mobility industries.
Is bluefiber "healthy"?
bluefiber is designed for indoor use and combines effective acoustical solutions with a substantial approach.
Made from 100% pure Polyester fibers, bluefiber products are completely recyclable, free from odor and safe to use.
Their open porosity allows them to absorb sound efficiently without the use of chemical additives. bluefiber products are low in emissions, durable, wear-resistant, mechanically stable, resistant to humidity, thermoformable, insulating and flame-retardant.
These features make bluefiber products ideal for use in residential, commercial, and public spaces. Applications include room partitions, panels, clouds, baffles, acoustic planks, and acoustic fillers or cavity resonance absorbers, providing effective solutions for improving room acoustics.
Individual requirements can also be met. The bluefiber product range encompasses standard products as well as custom solutions that make rooms more quiet and more comfortable - with tested quality and a sustainable approach to materials.
What is finexus® made of?
Finexus® is Sandler's patented nonwoven for the mobility sector, a 100% Polyester Monomaterial, i.e. doing without glass fibers, binders, or backing materials.
The single-material composition facilitates recycling and supports closed-loop material cycles in the automotive industry. Depending on the specific application, finexus® can contain up to 80% recycled fibers, combining technical performance with the industry's growing focus on circular economy. Apart from its sustainability benefits, finexus® scores with acoustic effectiveness, thermal insulation, heat resistance, flexural rigidity, robustness, and resistance to water pressure. These properties make finexus® suitable for a range of automotive applications, such as underbody shields, package trays, wheel well liners, headliners, trunk liners, and frunks.
Together with bluefiber and polyniq®, finexus demonstrates how Sandler develops nonwovens for various industries - always tailored-made to the specific requirements of the application.
Responsibility starts with Selecting the right Material
The requirements towards properties of modern nonwovens are manifold. Apart from functionality and quality, the responsible selection of raw materials is a central aspect especially in sensitive fields of applications.
With bluefiber, polyniq®, and finexus®, Sandler develops specialized solutions for various industries and applications. All our product brands represent an application-driven approach to development which translates Sandler's cross-technological competence into high-performance functional nonwovens.
