ROLLERS 1093-B
RESISTANCE AND HIGH TECHNOLOGY

This composition is the latest generation of RPA technical rollers.

Its unique mineralogical composition constituted of a ceramic matrix of very high purity raw materials provides to this roller quality a high flexural strength without compromising the resistance to thermal shock.

It is recommended for the production of large format and high load tiles specially for technical porcelain tiles produced in wide loading kilns.
