Crystal-Clear Optical Performance

Acrystex PM-600 offers exceptional clarity, rivaling that of PMMA. Its high transparency makes it ideal for optical components, lampshades, and other applications where visual appeal is crucial.

Versatile Molding Capabilities

This SMMA resin excels in both injection and extrusion molding processes. Its low mold shrinkage (0.3~0.7%) ensures excellent dimensional stability, perfect for crafting precise parts and products.

Heat and Impact Resistant

PM-600 boasts impressive heat resistance with a Vicat softening temperature of 106°C. It also offers good impact strength (3 KJ/m² at 23°C), making it suitable for durable household items and toys.
