PR-1130 artificial stone resin demonstrates a balanced mechanical profile compared to conventional unsaturated polyester resins used in engineered stone production.
With tensile strength around 40 MPa, flexural strength approximately 70 MPa, and Barcol hardness near 30, this resin meets the typical performance requirements for decorative artificial stone and interior applications.
While certain high-end market alternatives may offer higher hardness or heat distortion temperature (HDT > 55 °C), PR-1130 prioritizes process stability, controlled curing behavior, and cost-efficient performance, making it well-suited for standard artificial stone slabs, tiles, and molded products exposed to low-to-moderate mechanical stress.
This balance between mechanical properties and workability positions PR-1130 as a reliable and economical choice for manufacturers targeting consistent quality rather than over-engineered specifications.
