Ultimately, HYTAC-C1R resulted in equivalent or improved optical properties compared to PEI and
acetal, while improving material distribution and leading to stronger cups.
In the case of
acetal copolymer, the challenge is to develop a low-gloss material with no sacrifice in overall appearance (no surface defects), one that is colorable in a full range of colors, meets UV requirements, and maintains a good balance of mechanical properties, all at a reasonable raw material cost.
The
ACETAL valves perform at temperatures of -20[degrees]F to 180[degrees]F.
In one case, a watch manufacturer switched from metal to gears made of Celcon
acetal copolymer and Vectra liquid crystal polymer.
Consequently, in a simultaneous reaction scheme [TABULAR DATA FOR TABLE 2 OMITTED] where the poly(vinyl
acetal) is produced directly from PVAc, even in the presence of C[O.sub.2], the rate of acetalization should be significantly higher than that of the initial hydrolysis/alcoholysis to ensure that the concentration of OH groups remains low.
Plastic (
acetal) Newlocs offer light weight and are available in inch and metric sizes.
The valves below were made from aluminium and phosphor bronze/nylon and are now made from
acetal.
In his 40-plus years of experience with rotational molding, Beall has encouraged attempts to rotomold nylon,
acetal, polycarbonate (PC), and other engineering resins.
Aardalloy 3300 POM Alloy is a medium-viscosity, high-heat, homopolymer
acetal alloyed with elastomers and modifiers that increase impact strength and elongation.
monocytogenes as well as
acetal resin or reinforced plastic wall paneling.
The Techtron PPS (polyphenylene sulfide), Ketron PEEK (polyetheretherketone) and a porosity-free
acetal copolymer provide high stiffness and dimensional stability to various structural components of the Varioscope M5 system.
Keywords: By reacting an alkoxysilane
acetal with a sulfurating agent including certain novel mercapto silanes, useful in providing rubber tires with improved properties.
