Liquid and paste pigment dispersions for coloring PVC plastisols, urethanes
, epoxies, calendered PVC film, and other polymers.
with embedded ceramics can be optimized to resist not only sliding abrasion, but also impact, or various combinations of the two," said Roberge.
In this study, we analyzed the modulatory effects of pequi fruit on oxidative stress induced by urethane
carcinogenesis by measuring in vivo DNA damage through biochemical, immunohistochemical, and molecular biology assays.
Properties Dynamic mechanical properties such as E', E", and tan [sigma] of PBS-a were determined and compared with those of poly(benzoxazine-co-urethane)s with different weight percents of urethane
. Figure 3 shows the temperature dependence of E', E", and tan [sigma] for the prepared PBS-a and poly( benzoxazine-co-urethane)s.
But there is a great deal of speed (a fully completed production run can be completed in as few as three days) and flexibility achieved with cast urethanes
, as well as acute surface detail.
Additionally, the company's Asia-Pacific prices will go up by up to USD0.50 per kg for urethane
pre-polymers and speciality curatives.
The last class of urethanes
are polyurethane dispersions (PUD).
UNI's bio-urethanes serve as a direct replacement of phenolic urethane
and can be used with current molding equipment in both nobake and coldbox processes.
processing lines may include bulk storage and blending, including fiber or filler; mold carriers, including clamps, turntables, and conveyor systems; auxiliary robotics, ovens, hydraulics, and materials-handling equipment; and SRIM preforming systems.
New process equipment is now available for producing cast urethane
parts that make it possible to "dial in" the mix that will result in the desired stiffness and resilience.
Prior to replacing his metal compliant rollers with those made of urethane
, Phil's late night pages would almost always be caused by a roller that had worn out and halted assembly at his metal fabrication facility.
The nation's fair trade watchdog said the joint venture, to be established in April, will have a market share of almost 60% and therefore must provide at cost price 7,000 tons of urethane
materials to rival companies within two years in order not to violate the Anti-Monopoly Law.
