Product Description

Bo Tech Co.,Ltd Cristobalite and Quartz powder - is to use high purity quartz for the raw materials prepared from high-tech Cristobalite powder is based on the Quartz raw material, pollution-free iron grinding, precision grading process produced a series of pCristobaliteowder products.
1) Features: 1, excellent optical properties. Cristobalite from quartz of 1.55 refractive index down to 1.48, which is closer to the PE, PP and some resin refractive index. Mixture of resin appear to be transparent, do not cover paint their own colors, and with other fillers will make the color lighter color distortion.
2, the high reflectivity. Specific structure of cristobalite powder will help light reflection, can replace the glass for reflective paint, can enhance skid resistance, and also improve the paint's reflective nature.
3, high brightness, low density, color and light. Cristobalite whiteness of more than 95%, in the paint, the paint used, can replace part of titanium dioxide, reducing costs.
4, anti-corrosion, anti-carved, scrub.
5, non-organic pollution, metal content is very low. UV coating can enhance the capacity, and has good insulating property.
6, excellent thermal shock resistance. Cristobalitepowder when heated at about 220-240 ℃, a degree of thermal expansion occurs,which is just a compensation for epoxy resin, plaster curing reaction at this temperature when the contraction, so that no deformation of the castings.
2) Application of Cristobalite :
1, suitable for precision casting, dental materials, electronic chip grinding, polishing materials, building interior and exterior painting, road reflective coatings, automotive primer, plastic, rubber, silicon rubber, adhesive.
2, suitable for epoxy resin casting materials, potting and casting applications.
