In 1938, a research director for Thann & Mulhouse, Joseph Zeltner, first conceived the idea of Nylon 11, which was suggested in the works of Wallace Carothers. [3] Thann & Mulhouse had already been involved in processing castor oil for 10-undecenoic-acid, which would eventually be converted into the first amount of 11-aminoundecanoic acid in 1940 with the help of coworkers Michel Genas and ...
Nylon 12 exhibits properties between short chain aliphatic nylons (e.g., nylon 6 and nylon 66) and polyolefins. [3] At 178-180 °C, the melting point of nylon 12 is the lowest among the important polyamides.
Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of PEBAX® and VESTAMID® E (Evonik Industries).It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG).
Polymers commonly crosslinked using the electron-beam irradiation process include polyvinyl chloride , thermoplastic polyurethanes and elastomers (TPUs), polybutylene terephthalate (PBT), polyamides / nylon (PA66, PA6, PA11, PA12), polyvinylidene fluoride , polymethylpentene (PMP), polyethylenes (LLDPE, LDPE, MDPE, HDPE, UHMWPE), and ethylene ...

Nylon is a family of synthetic polymers characterized by amide linkages, typically connecting aliphatic or semi-aromatic groups.. Nylons are generally white or colorless [1] [failed verification] [2] [failed verification] and possess a soft texture, with some varieties exhibiting a silk-like appearance.
Confused about the difference between setting powder and finishing powder? That’s completely understandable. At a glance, the two products look virtually the same (they either come in a loose ...
