1. Components:
         Ultrafine particles (two specifications of silica, magnesium oxide) of powdered products. 

2. Physics analysis:
                 1. Appearance: YF-510: Circular white flaky powder; YF-2000: white flaky powder.
                 2. Whiteness: YF-510: 94 with 0.5; YF-2000: 94.5 with 0.5
                 3. Fineness: YF-2000: 5.4 with 0.5 u
                                    YF-510: 8.9 with 0.5 u
                 4. Moisture: 0.5 the following
                 5. PH value :8.8-9.0
                 6. Range of: YF-2000 :45-50cc / 100g
                                        YF-510 :35-40CC / 100g (oil: DOP)
                 7. True proportion: 2.6
                 8. Closely the proportion of false: YF-2000: 0.32 with 0.02 g / ML
                                                YF-510: 0.53 with 0.02 g / ML 
3. Purposes:
         1. Talc used in plastics resin modified rubber of the die, rolling, extrusion and injection, such as processing performance, and can replace some of the more expensive of the (compound) 10-15% to reduce the cost of raw materials and to provide their properties.
         2. In the paint, coatings, resistance exposure, high-temperature, ultraviolet irradiation does not change color, a long-term basis to maintain the original luster and color, the better the performance Naisuan Jian corrosion and water resistance, and resistant to pollution And stronger anti-aging properties, wear resistance, steam and chemical stability, and more fire-retardant properties.
