Polyurethane resins and silicone rubbers

Prototypes from Silicone Molds for industrial pre-production uses, high functional compliance, excellent aesthetics

The two-component polyurethane resins (polyol and isocyanate) cross-link at room temperature by adding a suitable catalyst giving rise to a stable and irreversible compound with high mechanical strength and flexibility.

Polyurethane resins are characterized by a minimum linear shrinkage, rapid demoulding, high resistance to impact and abrasion, dimensional stability and excellent surface finish. They withstand high temperatures and have a low dielectric constant.

Being very fluid and flowing products, they are appreciated in rapid prototyping and in the construction of models as they penetrate widely into the mold (especially if worked in the vacuum chamber) faithfully reproducing every last detail of the latter.

The materials are characterized by a direct similarity with the homologous industrial polymers of which they try to replicate the physical properties. They are all in liquid form with the possibility of mass pigmentation.
