Created in 1938 by aeronautics engineer Louis Ulmer, the company has been expanding in two main areas :
Then comes 1970 when the two activities got separated.
SPN builds on its expertise and keeps growing in the transformation of high performance engineering plastic business (PEEK, PEK, PAEK, POLYIMIDES, PBI, PPO, PF, PEI, PAI, PES, PPS, PSU…).
The exceptional physicochemical qualities make those engineering plastics perfectly adaptable to high-tech sectors use such as aerospace, medical, transportation (automobiles, railway), chemical engineering, electronics and connections, mechanics, nuclear and cryogenics.
SPN vocation is to become the leader in the manufacturing of all plastics which uses are difficult and extreme (high temperatures, cryogenics, explosive gas, corrosive chemical products, humidity…).
