FTIR is also used for quality control of materials and for contamination analysis (surface or internal). 1. 500:. Homopolymer acetal is most commonly recognized as Delrin, resins that are currently made by the DuPont Company under the trade name Delrin®AF. Organically modified montmorillonites (Cloisite ® 20, 30B, 93A) with different surfactants (Table 1) were supplied by Rockwood Additives (Wessel, Germany). Easy to machine, acetal makes an outstanding choice for applications that require complex, tight tolerances. However, it took around 30 more years before a commercially viable product was first patented.

It is manufactured in a solution process by anionic or cationic chain-growth polymerization of formaldehyde (H2C=O), a reaction analogous to vinyl. Abstract ; 13. Acetal resins have well-balanced properties, including a hard self-lubricated surface and excellent chemical resistance, strength, stiffness, and toughness over a broad temperature range. POM is typically available in two forms: homopolymer and copolymer.
