(3) Polypropylene resin modification

Adding 2%~5% nano-SiO2 to polypropylene resin to make polypropylene products has significantly improved strength and toughness, good low-temperature impact resistance, dimensional stability, improved processing performance, and good surface finish. It is suitable for making automobile body protection plates, bumpers and equipment instrument components, etc. It can replace advanced materials such as nylon modified polyphenylene ether and plastic alloys, thereby reducing automobile production costs.
