Bakelite temperature

웹Phenolic foam, a thermoplastic material, can be produced at low (30-60 kg / m3) and high (80-120 kg / m3) density by adding inorganic blowing and hardening agents to phenol-formaldehyde bakelite. Temperature resistance is one of the best among foam materials (up to 150 ° C). It shrinks at high temperature, its compressive strength is low. 웹2일 전 · La Bakélite a été développée entre 1907 et 1909 aux États-Unis par Leo Baekeland, chimiste belgo-américain.Le produit fut breveté le 7 décembre 1909 [2]..
