Color stability PPA 4122-WH117, high reflectivity of American Amoco, automotive electronics

Description :

　　1、 Product Introduction

　　PPA (Polyphthalamide) has a tensile strength that is 20% higher than nylon 6 and higher than nylon 66 under high temperature and high humidity conditions; The bending modulus of PPA material is 20% higher than that of nylon, with greater hardness and the ability to resist long-term tensile creep; Moreover, PPA has stronger resistance to gasoline, grease, and coolant than PA; A high-temperature resistant nylon material that can withstand sustained high temperatures up to 200 ℃ and maintain good dimensional stability.

　　PPA raw materials are pre dried to a humidity level below 0.1%, and then packed into heat sealed metal bags or boxes. These containers ensure that PPA raw materials do not need to be dried again before processing. The acceptable humidity level for processing technology is 0.15% or lower. Processing wet resins can reduce their molecular weight, resulting in corresponding mechanical property losses. Using a desiccant bucket dryer, it is easy to dry the resin to a dew point humidity of 25 ° F or even lower at 175 ° F. The drying time depends on the amount of water absorbed and is generally within the range of 4-16 hours.
