Extenders for various applications

Due to its high purity, whiteness and brightness Crystal Quartz Sand from Schlingmeier is an ideal extender for synthetic resin bonded materials. The mechanical properties such as impact hardness, bending and tensile strength, compression strength, and the modulus of elasticity, can be improved. The coefficient of linear thermal expansion decreases. Shrinkage and increase in temperature during hardening can be reduced. Furthermore, both acid and alkali resistance can be increased. As quartz can be considered inert towards synthetic resin bonded materials, the working time is not affected.

The following table shows selected grades which are preferably used as extenders. All dry sands (T) can be supplied as blended grades. Please let us know your required grain size distribution.
