Manufacturer / Exporter / Supplier Of Omya Calcium Carbonate, Pipes & Profiles, Calcium Carbonate
vb​Filling polypropylene with up to 60 % calcium carbonate is a proven solution for running polypropylene on existing polystyrene thermoforming machinery with a comparable line performance and end-product quality. The use of calcium carbonate in PS products is also very popular, modifying both the mechanical performance and processing output. The main benefits of using Omya calcium carbonate in thermoforming include: Higher extruder output and faster cooling on chill roll Reduced cooling time in mold and faster cycles Higher stiffness Lower shrinkage Processing on existing PS thermoforming machinery More isotropic physical properties Improved forming accuracy
Omya's range of calcium carbonates (Omyalite and Omyacarb) is unparalleled, covers the entire spectrum of applications for pipes and fittings and has the following benefits: Improved processing (reduced cooling time) Reduced cycle time (fittings) Higher ring stiffness Mechanical requirements for PVC pressure pipes Homogeneous foam structure (structured wall pipes) Higher elastic modulusAdding more Hydrocarb to PVC profiles and sidings can yield substantial benefits. By choosing the right calcium carbonate, the process can benefit from: Higher impact strength Better gloss Superior surface finish Good processing at high loadings
The higher thermal conductivity and lower specific heat of calcium carbonate are key advantages in molding applications. The cycle time, stiffness and impact resistance will be favorably improved in injection molding and blow molding applications, which then leads to cost savings.Calcium carbonate offers substantial benefits in blow molding applications for producing bottles or containers, such as: Increased flexural modulus Sustained top load and drop impact Improved ESCR Reduced cycle time Lower melt temperature Reduced titanium dioxide content Improved printability
