Quartz stone is a composite material made of crushed stone bound together by polymer, resin with some newer versions using cement mix.
Quartz stone is used primarily for kitchen countertops and Quartz stone is less porous, more flexible, and harder than many types of natural stone. Less porous varieties are more resistant to mould and mildew than most natural stone types.Since it has a uniform internal structure, it does not have hidden cracks or flaws that may exist in natural stone. Its polyester resin binding agents allow some flexibility, preventing cracking under flexural pressure. But, the binding agents often continue to harden, leading to a loss of flexural strength over time. The polyester resins are not completely UV stable and engineered stone should not be used in outdoor applications. Continuous exposure to UV can cause discoloration of the stone, and breakdown of the resin binder.
