Problems solved by technology

[0002] Polypropylene has good mechanical properties and thermal stability, but also has good electrical properties, heat resistance and corrosion resistance, and is widely used in electronic communications, lighting fixtures, automobiles, electric tools, electrical switches and other fields. But its relatively Low thermal conductivity (0.21~0.26w/mk) limits its application range in lighting and communication heat conduc
