Скачать или смотреть Bonding Silicone to PP Reliable Adhesion on Low Surface Energy Plastics 🔧

Bonding silicone to PP (polypropylene) is challenging because PP is a low-surface-energy plastic, while silicone has inherently low adhesion—many adhesives bead up, peel, or fail after heat/humidity cycling. For manufacturers making seals, valves, wearable parts, or consumer housings, the goal is a durable PP-to-silicone bond that survives flexing, oils, and repeated temperature changes.

⚠️ Common pain points: poor wetting on PP, edge lifting after curing, bond failure under peel stress, inconsistent results between PP grades, and process steps that slow production (long cure or complex prep).

🔬 ZDS solution approach: combine the right chemistry with the right surface strategy. For PP, adhesion often improves with surface activation (plasma/corona/flame) or a suitable primer, then an adhesive designed for low-surface-energy substrates and silicone interfaces. Controlled viscosity helps prevent squeeze-out on thin seal lines and supports repeatable dispensing.

🏭 Manufacturer mindset: ZDS supports production validation—substrate identification (PP/PP+EPDM blends), surface prep windows, and testing plans (peel, thermal cycling, humidity, oil resistance). Learn more: 👉 www.zdschemical.com
