The main factors that affect the hydrolysis PBT terminal carboxyl group concentration. Since PBT containing an ester bond, at a temperature above its glass transition temperature of the ester bond is broken into the water will occur, so that hydrolyze to form acidic environment accelerates the hydrolysis reaction, a sharp decline in performance. Workaround: First, add hydrolysis stabilizers, such as carbodiimide modified materials SENXIN really good, hydrolysis stabilizers consumes carboxyl hydrolysis, slowing PBT acidic hydrolysis rate, improve hydrolysis resistance PBT resin. Second, by adding methods PBT closed terminal carboxyl group, lower terminal carboxyl group concentration, improve resistance to hydrolysis, such as epoxy functional group added with additives (such as SAG series, a styrene-PBT of - acrylonitrile random -GMA copolymer), by GMA PBT terminal carboxyl functional groups reacting with capped SENXIN modified materials, thereby increasing resistance to hydrolysis PBT. Environmental policy, regulate the introduction of intensive business sense so many PBT materials prepared pressures. But industry experts believe that such environmental pressure will be normal SENXIN modified materials useful, and with the country more and more attention to environmental protection, suspend production for rectification of heavily polluting chemical enterprises will be more and more. Green future is still the mainstream of PBT material development, in short, PBT raw materials need to be developed, but should focus on long-term perspective, coexistence with the environment.
