Chemical Structure

Formed from inter-reaction of polyols, diisocyanates, and short-chain diols.
Resulting in flexible and rigid segments within its linear polymer structure.
Properties influenced by polyols used—polyester-based or polyether-based—and reaction conditions and material ratios.

Physical Properties

Tests conducted using injection-molded samples that are pre-dried and conditioned under controlled temperature and humidity.
Factors such as part design, processing conditions, molecular orientation, internal stresses, moisture, annealing, and environmental conditions can significantly influence performance.

Chemical Properties

Chemical resistance varies significantly due to differences in composition and how each component reacts with other substances.
Specific stability tests—especially those assessing swelling and mechanical properties—are recommended for evaluating suitability in particular applications.

Fire Behavior

Plastics are inherently flammable and their fire behavior is categorized into:
- primary properties (such as flammability, flame spread, and heat release)
- secondary properties (like smoke density, toxicity, and flaming particles)
Factors like design and structure—such as the thickness of a cable sheath—can significantly influence outcomes like smoke density.

Food Contact

Elastollan^® FC portfolio includes over 20 ether- and ester-based TPU products designed for food contact applications.
Comply with EU and FDA regulations (except for certain concentrates)
Manufactured under strict GMP standards
Processors and manufacturers must conduct thorough evaluations, referencing regional, EU, US, and globally accepted standards.

Processing Recommendations

Elastollan^®, the thermoplastic PU elastomer (TPU) of BASF, which is developed, produced and marketed by BASF Polyurethanes for the European Market at the site in Lemförde, can be processed in a targeted manner using various methods.

Elastollan^® TPU is a versatile material requiring careful handling to maintain quality.

Must be stored in sealed packaging and dried before processing to avoid moisture-related defects.
Additives and colorants can be used to tailor properties, and regrind material may be reused if uncontaminated.
Post-processing treatments like annealing enhance mechanical performance.
Proper ventilation is essential for safe handling.

Injection molding of Elastollan^® demands precise temperature control and mold design.

Melt temperatures vary by hardness.
Mold features like gating and venting affect cycle times and part quality.
Shrinkage must be accounted for.
Advanced techniques such as multicomponent molding are supported.
Common defects can be mitigated through optimized processing parameters.

Extrusion requires specific equipment configurations and cooling strategies.

Single-screw extruders with grooved feed zones and screen packs ensure melt homogeneity.
Low melt strength necessitates careful cooling and calibration, often using water baths or spray rings.
Applications include tubing, sheathing, and film extrusion, with options for coextrusion and foam extrusion.

Machining Elastollan^® involves controlled cutting and cooling to prevent damage.

Techniques like turning, milling, and drilling require reduced speeds and sharp tools.
Grinding should use high-porosity wheels with coolant.
Punching is viable for chipless machining.
Adhesive bonding is possible with lubricant-free grades using polyurethane or epoxy adhesives.

BASF’s quality management system ensures consistent product performance.

Certified under ISO and IATF standards; emphasizes error prevention, staff engagement, and continuous improvement.
Customer feedback and internal audits support high-quality outcomes across all business sectors.
