Polyuréthane
FRLe polyuréthane désigne une famille de polymères utilisés sous différentes formes, dont des mousses, des revêtements et des élastomères. Le comportement dépend de la formulation et du procédé. Un polyuréthane élastomère peut servir à fabriquer ou à recouvrir des pièces destinées à des contraintes de contact, de charge ou d’usure. La dureté, la température, les produits chimiques, la géométrie et le cycle de service doivent être précisés avant le choix du matériau; tous les polyuréthanes ne présentent pas les mêmes propriétés.
ENPolyurethane is a family of polymers used in forms such as foams, coatings and elastomers. Behaviour depends on formulation and processing. Polyurethane elastomers can be used to make or cover parts subject to contact, load or wear. Hardness, temperature, chemicals, geometry and duty cycle should be specified before material selection; not all polyurethanes have the same properties.

- BIBusiness intelligence turns data into information for decision-making. It combines data preparation, analysis and visualization but does not itself guarantee data quality.
- CRMCRM comprises practices and tools for managing customer and prospect relationships. CRM software centralizes contacts, sales opportunities and interaction history.
- ÉlastomèreAn elastomer is a polymer material capable of deforming and recovering much of its shape after load removal within its operating limits. It may be used for flexible parts, coverings, seals or contact components. Hardness alone is insufficient for selection: temperature, chemicals, abrasion, compression and ageing should also be considered. Compatibility must be confirmed for the exact formulation and application.
- Emballage de protectionProtective packaging is designed to limit product damage during handling, storage or transport. It may combine a crate, blocking and cushioning adapted to the product. Design considers mass, fragility, handling access and the logistics route. Humidity, vibration, shock or export requirements must be defined and validated using appropriate methods; no package protects against every risk.
- EmbeddingVector representation of a text (often 1,024 to 3,072 dimensions) capturing its meaning. AI engines convert indexed content and the user's question into embeddings to measure semantic similarity.
- ERPAn ERP integrates business functions through shared data and processes. In a plant it can coordinate orders, purchasing, inventory, planning and accounting depending on the deployed modules.
