Somos 9420 is ideal when attempting to simulate the structural properties and aesthetics of polypropylene.
This "polypropylene like" rigid resin is produced in opaque white using the SLA process. Since Somos 9420 is very flexible; snap fits, tabs and features that require a certain degree of rigid elasticity, are an ideal fit for this SLA resin.
Rigid yet flexible: enclosures, packaging and containers appear more realistic than traditional rigid resins, yet can still be primed painted and used as mold patterns.
