Bostik’s Low Pressure Molding (LPM) Solutions
Overview
Bostik, an Arkema company, is a leader in smart adhesives and low pressure molding (LPM) technology. LPM is used to encapsulate and protect electronic components from moisture, dust, dirt, and debris.
Key Benefits of LPM
- Simplified Process: A fast, single-step method combining plastic injection and resin potting.
- Energy & Cost Efficiency: Low injection pressure reduces equipment needs and energy consumption.
- High Performance: Provides water-tight, shock-resistant, and high-temperature stability for electronics.
- Eco-Friendly: Solvent-free, bio-based materials (up to 80%), recyclable excess material, and long shelf life.
