Frost resistant and creep resistant PPA AS-1945 HS American Amoco Power Valve Industrial Components

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.

　　Characteristics: Dimensional stability; High rigidity; High intensity; Frost resistance; Creep resistance; Chemical resistance; heat-resisting; Ethylene glycol resistance; Thermal stability

　　Usage: power/other tools; Valves/valve components; Industrial components; Industrial applications; Thick walled accessories (components); Machine/mechanical components; Metal substitution; Parts under the hood of a car; Applications in the automotive field; shell

　　Among common engineering plastics, only PPA can achieve this indicator, and the additional advantages brought by PPA include a thread torque of up to 100N. m and a lower water absorption rate than PA66 GF. For a moment, 'Luoyang paper is expensive'. PPA has entered the water meter industry, leaving the original PPE, POM and other materials with no suitable options. The most common PPAs in the water meter industry include PPA 6T/66+GF50 enhancement, PPA6T/6I/66+GF50 enhancement, etc.

　　PPA still has an advantage over PPE, which is the failure mode of thread stress. It is generally not easy to twist, and even if it fails, it is only in the sliding wire mode.

　　Finally, the blue cases we often see are all spray painted, but in essence they are still cast iron. When can we replace steel with plastic in large quantities? The road for plastic people is still long.
