The medium melt products are homopolymerized polypropylene resin. With high rigidity, good heat resistance,good deformation resistance. It is widely used in the injection molding of electric kettles, rice cookers, electric hair dryers, other small household electrical appliances, and a range of household and toy products.
1. Good fluidity and crystallinity, short molding cycle;
2. High rigidity and hardness, end products with good scratch resistance;
3. Good heat and deformation resistance, long heat contact time, and extended service life.
It is widely used in the injection molding of electric kettles, rice cookers, electric hair dryers, other small household electrical appliances, and a range of household and toy products.
