Use of Dolomite Powder (1000 Mesh) in Rubber Band Manufacturing
Dolomite powder (CaMg(CO₃)₂) with 1000 mesh fineness is an ultra-fine mineral filler that plays multiple roles in rubber band production.
Key Functions in Rubber Bands
Filler & Cost Reduction
Replaces part of natural/synthetic rubber to lower production costs without drastically affecting elasticity.
Improved Processing
Ultra-fine particles (1000 mesh) disperse evenly in the rubber mix, improving mixing and extrusion properties.
Enhanced Surface Finish
Produces smoother, more uniform rubber bands with less surface roughness.
Tensile Strength Adjustment
Controls hardness and flexibility balance, ensuring rubber bands are strong but still stretchable.
Heat Resistance
Dolomite’s mineral nature helps reduce heat build-up during stretching, improving durability.
Color Base for Pigmentation
Fine white dolomite provides a neutral background, allowing bright, consistent colors in colored rubber bands.
