CHEERSPEARL 7000 series (Patent NO. ZL 201710603837.9) is one of the main products of Cheerchem and it has obtained high-tech product certification (Certificate NO. 170581G2225N). we have a dedicated application testing platform.
Product Characteristics
CHEERSPEARL 7000 series is a kind of powdery organic silicone resin, which is used as an additive of plastic, rubber or coating. It has the following characteristics:
· Excellent light diffusion performance
· Narrow particle size distribution
· Excellent hydrophobicity
· Excellent lubricity
· Lower density than inorganic powder.
· Better heat resistance than organic resin powder
· Insoluble in organic solvents
· Don’t melt at 900 ℃ and the weight loss is less than 5% at 400 ℃
· Low adhesion, good dispersibility
· Keep true spherical silica particles after calcination
Application
◆ Display and Illuminating Industries: Lighting diffusion agent for LCD/LED display panel or LED illuminator;
◆ Synthetic Resin: Improve the wear resistance, anti-blocking and smoothness of PMMA, PS, PC, PET/PBT, ABS, EVA and other synthetic
resins, and also used as the opening agent, anti-fogging agent, or lighting diffusion agent for PE, PP, PVC and other plastic films;
◆ Rubber Industry: Improve surface smoothness and wear resistance;
◆ Coating and Ink: Adjust glossiness and color brilliance, anti-blocking, improve wear resistance.
◆ Cosmetic: Smooth hand feeling agent and filler (please carefully evaluate feasibility before use),
◆ Others: Improve the dispersion，flowability or deflocculation of pigment and ceramic powder.
