PVC Aircraft Bellevilles - Request for Information


PVC: is the abbreviation for polyvinyl chloride, a commonly used thermoplastic.  PVC is chemically resistant and maintains integrity and stability in applications where metal would otherwise corrode. 


Aircraft:  deals with the development and manufacturing of products, structures, materials and devices used in aircrafts for a variety of markets.  Aircraft standards are established based on the extreme temperature, pressure and ware exposure faced in air operations.  

Bellevilles: sometimes referred to as disk springs, may be stacked to create a more constant spring effect and various degrees of deflection according to the application needs.
