all polyphenols absorb a certain amount of water, causing plasticization&size change. for example, nylon 6, 6, at 23 degrees f, the relative humidity is , it can absorb 8.9% of the moisture, which makes its glass transition temperature from 6.5 c to a 20 degree temperature, the size increased 2.3%. under the same conditions, the ppa resin can absorb about 6% of the moisture, but the vitrification temperature of tg will not be less than 40,&the accompanying size increases not more than 1%.

[ temperature / cooling time] because the pa46 curing speed is very fast, so its cooling time is also very short. for this reason, the plasticizing time is usually the determinant of the molding cycle. in theory, the processing process of pa46 can be carried out within a wide range of temperatures. in order to obtain good dimensional stability&fluidity, the recommended temperature should be higher than 80 c. in order to reduce the later shrinkage, increase fluidity, improve the strength of weld line&improve toughness&surface quality, the temperature can be increased to 120 degree c/even higher.
