[0002] PP sheet is one of the main materials in the production of multi-layer boards. It is mainly composed of resin and reinforcing materials. The reinforcing materials are divided into several types such as glass fiber cloth, paper base, composite materials, etc. The semi-cured sheets used in the production of multi-layer printed circuit boards mostly use glass fiber cloth as the reinforcing material.

[0003] Polypropylene (PP) extruded sheet is a plastic sheet made by adding various functional additives to PP resin and undergoing processes such as extrusion, calendering, cooling, and cutting. PP sheet is a semi-crystalline material. It is harder and has a higher melting point than PE. Since the homopolymer PP temperature is very brittle above 0°C, many commercial PP materials are random copolymers with 1% to 4% ethylene or clamp copolymers with a higher ethylene content. Copolymer PP materials have a lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but have stronger impact strength.
