NYRIM® P1-20A Prepolymer

Technical Datasheet | Supplied by Brüggemann
NYRIM® P1-20A Prepolymer by Brüggemann is a high molecular weight, viscous elastomeric polymeric liquid activator in the anionic polymerization of AP-NYLON® Caprolactam, along with the NYRIM®C1-Catalyst. It is recommended for two component casting equipment and cast polyamide. This system enables the production of homogeneous cast parts of a reproducible high quality (fast demolding after less than 10 minutes) and low casting temperatures (melt: 95-105°C, mold: 140-150°C). It is suitable for large, low-tension semi-finished products, such as bars, tubes, and plates, to complex, often thick-walled molded parts that cannot be manufactured through injection molding or extrusion. The product is used in rough and tough applications. The shelf life of the product is at least 24 months under (dry, 25°C) conditions. Recommended dosage level of NYRIM® P1-20A Prepolymer is 11-22%.
