How to select high temperature resistant engineering plastics?
High temperature resistant engineering plastics is a kind of engineering plastics that can maintain its own high mechanical properties under high temperature conditions.
The common engineering plastics without filling and high temperature resistance include PSU engineering plastics, PES engineering plastics, Pei engineering plastics, peek engineering plastics, etc. the engineering plastics with high temperature resistance after modified filling include pa66+ glass fiber / mineral fiber, pps+ glass fiber / mineral fiber, LCP engineering plastics, etc.
So how do we choose these high temperature resistant engineering plastics? Generally speaking, engineers will follow certain principles when selecting high temperature resistant engineering plastics. Jiangmen Wantong Plastics Co., Ltd. has sorted out some for your reference here.
1. Considering the heat resistance of engineering plastics
1) it is sufficient to meet the heat resistance. Do not choose too high, which will increase the cost.
2) general purpose plastics shall be used for modification as far as possible. Most high-temperature resistant engineering plastics belong to special engineering plastics, and their prices are relatively high, while the prices of general-purpose engineering plastics are relatively low.
3) general engineering plastics with large fluctuation of heat-resistant modification shall be selected as far as possible.
2. Consider elements of heat resistant environment
1) instantaneous heat resistance and long-term heat resistance.
2) dry heat resistance or wet heat resistance.
3) medium corrosion resistance.
4) heat resistance with or without nitrogen.
5) on load heat resistance and off load heat resistance.
