PR-1130 offers mechanical performance aligned with typical polyester artificial stone resins, with balanced tensile (~40 MPa) and flexural (~70 MPa) strength, and a Barcol hardness (~30) suitable for standard decorative and low-to-medium stress stone products. While some competitive resins achieve slightly higher hardness/HDT figures (e.g., Barcol ≥40, HDT ≥55 °C), PR-1130’s profile delivers a cost-efficient balance of workability, cure schedule, and dimensional stability that matches common engineered stone applications in interior surfaces and light traffic areas.
