Electronic Material PP Black: Characteristics, Applications and Development Prospects Introduction

With the rapid development of electronic products and the advancement of the intelligent trend, electronic components have higher requirements for material properties. Polypropylene (PP), due to its advantages such as light weight, chemical corrosion resistance, low cost, and convenient processing, is widely used in the electronic and electrical industry. However, ordinary PP has deficiencies in heat resistance, flame retardancy, and electrical insulation performance, which are unable to meet the strict requirements for safety and reliability of electronic components. 

Therefore, electronic material PP black came into being.
