SENXIN how modified materials, Xin-modified materials, wholesale and retail high-quality modified material

The main factors that affect the hydrolysis PBT terminal carboxyl group concentration. Since PBT containing an ester bond SENXIN modified material, at a temperature above its glass transition temperature under water occurs ester bond breaking, hydrolysis of the acidic environment of accelerating hydrolysis reaction, a sharp decline in performance. Workaround: First, add hydrolysis stabilizers, such as carbodiimide modified material SENXIN service attitude okay, 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 PBT modified materials SENXIN really good, adding additives such as epoxy functional groups (such as SAG series, a styrene-- -GMA acrylonitrile random copolymer), GMA PBT functional group by reaction with the carboxyl end group capped, thereby enhancing the hydrolysis resistance of PBT. PBT plastic materials are presented under high pressure granulation process: 1 raw material sorting:. PBT plastic materials packaging films, such as bags lined with film, food packaging film, commodity packaging films, including big films, most of these films are color, She has light blue, black, preferably separated by the color material. 2. crushing washing, after sorting the raw material into the grinder, washing feeder automatically after crushing, pulverizing the best material to flow sink after rolling again, the purpose is to further wash clean point, you can put a base in cleaning the pool and other cleaning products. SENXIN how modified materials, Xin-modified materials, wholesale and retail high-quality modified material provided by Dongguan Chang Ping-Xin plastic materials.
