Overmoldable Silicone for Smart Wearables
Keywords: overmoldable LSR, wearable silicone, skin-safe liquid silicone, low migration LSR
Key sentence: One-step overmold LSR bonds firmly to PC and TPU without primer, cutting cycle time for smart wearable enclosures.
Momentive rolls out a skin-safe liquid silicone rubber optimized for fitness trackers, medical patches and smart watch seals. The self-adhesive LSR bonds directly to common engineering plastics during injection molding, removing plasma or primer treatment. It delivers low surface migration and passes ISO 10993 skin irritation tests. The material resists sweat, sunscreen and hand sanitizer, preventing sticky residue after long wear. Wearable brands are under pressure to shorten molding cycles and reduce reject rates. This formulation balances soft touch and dimensional stability, supporting thin-wall designs. It is available in translucent and custom colors for mass production orders.
