Themajor raw material for foam is polyol, tolylene
diisocynate, methylene andadditives.
diisocyanate (TDI) was used as a coupling agent.
Asthma due to non-occupational exposure to toluene (tolylene
A dispersion of PEG based acrylate functionalized hydrogel was also polymerized, composed of tolylene
diisocyanate (TDI 2,4), PEG of Mn = 6000 g/mol, hydroxyehtylmethyacrylate (2-HEMA), and PEG monomethacrylate of Mn = 2000 g/mol.
The reaction was conducted using 3.00 g (0.0044 mol) of 2 and 8.80 g (0.0088 mol) of the polypropylene glycol, tolylene
, 2,4-diisocyanate terminated (M.W.
The probe will examine the imports of tolylene
diisocyanate manufactured in Japan, South Korea and the United States, the Ministry of Economy, Trade and Industry (METI) said, quoting an announcement by the Chinese government.
Waste soft PUR foam based on tolylene
diisocyanate and polyether polyol with molecular weight of about 3600 g [mol.sup.-1] (Megaflex-Schaumstoff GmbH, Germany) was delivered by Bossmebel, Poland.
diisocyanate (TDI) has been used for the production of flexible slabstock foams for the last 40 years or so.
Regulation governing isocyanate exposure, especially tolylene
diisocyanate (TDI), have fueled movement to methylene-di-p-phenyl diisocyanate (MDI) development of low TDI prepolymers and the use of chain extended or trimerized isocyanates in one shot systems.
Using this diol, four novel hard segmented PUs have been synthesized from the reaction of ODBNMD with 4,4'-diphenylmethane diisocyanate (MDI), tolylene
2,4-diisocyanate (TDI), isophorone diisocyanate (IPDI), or hexamethylene diisocyanate (HDI).
The PA6-based polymer composites were obtained by polymerization of fine mechanically mixture of [epsilon] -caprolactam (OAO Kuibishevasot, Russia) in amount 100-220 g with calculated amount of filler using sodium as catalyst and tolylene
2, 6-diisocyanate as cocatalyst at 140-160 [degrees] C degrees for 12 h.
