Key Benefits of Palapreg P 171-903B
- Steady thickening behavior
- Good mechanical properties
- Excellent heat resistance
- Excellent surface gloss
Applications
This resin is intended for SMC and BMC production. It is mainly used together with Palapreg / Synolite high polymer components for low shrink or low profile SMC/BMC applications. The resin can be readily thickened with magnesium oxide.
Why Low Shrink and Surface Gloss Matter in SMC/BMC Molding
Sheet and bulk molding compounds are typically compression molded at elevated temperature and pressure, and the resin’s shrinkage behavior during cure has a direct effect on the surface quality and dimensional accuracy of the finished part. Excellent surface gloss and low shrink or low profile performance, achieved together with Palapreg / Synolite high polymer components, are especially valuable for parts where cosmetic surface quality matters, such as visible automotive panels or electrical housings, since post-mold finishing operations can be reduced or eliminated. Steady thickening behavior when combined with magnesium oxide is important for SMC/BMC processors because it gives a predictable, repeatable viscosity build during the maturation stage before molding, supporting consistent handling and flow characteristics batch to batch. Good mechanical properties and excellent heat resistance further support the resin’s use in structural or under-hood automotive components and electrical housings exposed to elevated service temperatures. Molders should always confirm current thickening schedule, cure profile, and formulation ratios against the latest technical data sheet for their specific SMC/BMC process.
