Acrodur® binders for lightweight natural fiber composites

Nonwovens based on glass fibers are widely used in construction applications. BASF’s tailor-made Acronal® and Acrodur® binders ensure that the substrate provides sufficient mechanical performance and attains special resistance to heat, water, solvents or environmental stress.

Excellent properties, such as mechanical strength, resistance to abrasion, and slip resistance, together with a broad range of possible degrees of hardness make Elastollan® an ideal material for footwear applications.

Soft grades are used for cushioning elements, medium hardness grades are suitable for compact or combination soles and hard grades are the best solution for heels and heel tips. Anti-static agents can be added to the thermoplastic polyurethane (TPU) Elastollan® so that it can be used for safety footwear.

When it comes to shoe uppers, Elastollan®-based materials are distinguished by their good tear and abrasion resistance and pleasant surface feel.

• BASF’s polyamide with a PCF of zero, produced with electricity from renewable sources without compromising on quality and performance.
• Meet Ultramid® Biomass balance (BMB), our line for products with attributed renewable feedstock.
• BASF's high-quality polyamides, for the production of which raw materials from the chemical recycling of plastic waste and end-of-life tires are used instead of fossil raw materials and allocated using a mass balance approach.

Flexible films made from Elastollan® not only look appealing, but they also protect, seal and provide adhesion. Elastollan® has a versatile set of properties so that it has numerous possible applications.

Outstanding elasticity means that the thermoplastics polyurethane (TPU) Elastollan® is particularly suitable for producing mono- and multi-filaments, as well as for coating polyester and glass fibers used for shading systems and covering chairs.

Elastollan® can also be worked into nonwoven fabrics using the melt blown as well as spun bond techniques. For these applications, particular importance is placed on product benefits such as elasticity of up to 500 %, high rebound and adjustable gas permeability.

In textile membranes and medical membranes, Elastollan® offers high water-vapor permeability whilst still being wind- and waterproof, combined with good elasticity.

Even without the use of additional additives, the unique morphology of Elastollan® grades SP 806 and SP 883 produces a matte, non-blocking film surface. It is characterized by a low surface tension and very good adhesion to the substrate. The surface is particularly skin-friendly, which is vital for medical applications among others.

Elastollan® Hotbond is a TPU for melt adhesives. The melt flow index can be adapted to the individual classes.
