PC material testing items and requirements

Recently we often received a customer call, to understand the test items and requirements of the PC materials, and now I take you to sum up it!

1.PC aggregate inspection items

1. Plastic melt index

2. Plastic moisture content test;

3. Density test;

4. Plastic particles injection into the standard test spline, the tensile, impact, Vicat softening point, surface hardness and other physical properties;

5. Appearance inspection: the standard color of plastic particles;

1. Stretch and bend strength and modulus;

2. impact performance;

3. Optical properties: light transmittance, haze;

4. Thermal properties: heat distortion temperature, Vicat softening temperature and glass transition temperature

5. Heating test

3. PC board resistance to environmental performance test

1. Hot and humid aging

2. Salt mist aging;

3. UV aging;
