SMC - BMC Type Polyester Resins

Highly reactive SMC/BMC type polyester resins are one of the indispensable materials in the industry for fast production cycles and high-performance products. These special resins are at the heart of composites in sheet (SMC) and paste (BMC) form used in hot press molding processes.

SPECIAL BENEFITS

High reactivity with fast production cycles
Smooth, wave-free, glossy surface quality
The possibility of serial and economical production
Thermoplastic compatibility and superior thickening

SMC (Sheet Molding Compound)

High performance resins used in sheet molding processes, suitable for mass production.
