NH-Hcarb NHGKS29 – CaCO3 Powder for uPVC Profiles

NH-Hcarb NHGKS29 is an ultra-fine uncoated calcium carbonate powder specifically designed for uPVC Profiles. For window and door frames, structural “stiffness” is the most important factor. The high purity of 98.5% CaCO3 reinforces the PVC structure, preventing the profile from warping over time. The 98% whiteness ensures that the frames stay bright and resist yellowing when exposed to sunlight, maintaining the building’s aesthetic for years.
