标题: 关于塑料材料选择,主要看那几项
本人将要设计新产品,他的工作环境如下;

1. Applied Enviroment Temperature from -40 to +80 degree( -10 to 65 is the TFT recommend working temp.)
2. Dropping impact testing.
3. UL(V1) is a must.
4. High stiffness w/o inner metal support.
5. Steady force testing( kind of surface stiffness stiffness)

我想选择GE 的材料,但不知道在材料的SPEC上主要看那几项,来满足产品的要求.
