China is able to supply itself in the meantime with both plastics as well as important preliminary products such as caprolactam. Capacities for base resins and compounds are increasingly being expanded in the country. Ongoing high prices for PA66 compounds are leading to substitution with PA6 in many applications. Note de contenu : - Market development - Expansion in base resins - Worldwide higher compounding capacities - Sharp price increase for benzene - High-performance halogen-free flame-retardant compounds - One material for multiple performance classes - Halogen and phosphorus-free alternative - Efficient heat dissipation - High temperature stable PA6 and 66 - new weldable compounds - Extreme notched impact resistance for oil pans - Higher temperatures in engine air management - Thermoplastic composites in large series - Weight reduction with hollow glass spheres - Electromobility : market of the future - FIGURES : 1.
