Firstly, for starters, Zero CaCO3 unique formulations ensure our formwork premium quality. CaCO3 formwork are easier to deform under the burning sun for a longer time. Below are comparisons between zero-caco3 formwork and Caco3 formwork.
Left is our 0-caco3 formwork and right is caco3 formwork:
Secondly, our dimensions are accurate to within ±0.1mm,and density is accurate to within ±0.02. The horizontal variation rate by heating is -0.15%, and vertical variation rate is -1.35% and our Diagonal tolerance is below 3mm.
Thirdly, the surface hardness of our formwork is 80-90Shore D,and others is 60-65Shore D,below are picture comparison.
Left is our formwork and right is others’ formwork.
