Product Details

1.About reflective glass beads

reflective glass beads are mainly used for retro-reflective products, such as retro-reflective fabric, retro-reflective material, retro-reflective film, and when properly used, help enhance the visibility of the user in nighttime or low-light conditions when illuminated by a light source such as headlights, by returning the light back toward the original source and reaching the automobile driver's eye, it enhances conspicuity and safety.

4.Characteristics

ngredients SiO2, Al2O3, etc. Features Gray powder Application characteristics:
1. Low price;
2. Reinforce the toughness of the plastic without reducing its own stiffness;
3. The high melting point can improve the flame retardant property of the filler and the Vicat softening point;
4. Good electrical insulation, can be used for filling high-insulation polymer;
5. Increase the fluidity of the filler, increase the processing property of the plastic, and improve the surface leveling of the engineering plastic to solve the surface problem of the glass fiber reinforcement;
6. Can effectively reduce the shrinkage rate of the filler;
7. The true density of 1.78g/cm3 (stack density 1.12g/cm3) can obviously achieve the effect of weight loss compared with engineering plastics filled with glass fiber, calcium carbonate and talcum powder;
8. Corrosion resistance; dosage: Air Micro Company recommends that the general dosage of PP and PA is 30-40%, the amount of HIPS and PBT is generally 7-15%, and the amount of ABS is generally 5-7%. In the use of conventional engineering plastics, the hollow microbeads are modified with a silane coupling agent KH-550 in a high-speed mixer, and can be appropriately stirred and mixed with engineering plastic pellets, and then directly extruded in a twin-screw machine. .
