Fuel tanks

•  Automotive manufacturers strictly forbid any repairs on fuel tanks

Radiator housing

•  The radiator assembly may reach significantly higher temperature

Use of plastics in automotive engineering is growing

•  Lower manufacturing costs
•  Flexible properties and types
•  Reduction of car weight
•  Resistance of corrosion
•  Smoother surfaces through improved design and aerodynamics
•  Noise reduction
•  High potential for development
•  Recycable

Cost savings – insurance companies/customers

•  Insurance companies prefer to repair rather than to replace
