Baypreg® FG

Baypreg FG system is a two component polyurethane system used in compression molding of fiber-reinforced sandwich panels to produce a variety of automotive parts. Some identified applications include door panels, sunshades, spare tire covers, load floors, etc. The Baypreg FG system provides lightweight alternatives to ABS, PP, SMC, and wood products while demonstrating very high flexural stiffness and excellent thermal properties. Baypreg FG system offers very diverse properties over a wide range of part thicknesses and densities while still providing cost effective substrate parts when combined with reinforcing materials. As with any product, use of the Baypreg FG system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.

The isocyanate, Component A, is based on diphenylmethane diisocyanate (PMDI). It should be stored in tightly closed containers and protected from moisture and foreign materials, which can adversely affect processing. It will react slowly with water to form ureas and liberate carbon dioxide gas, which may cause sealed containers to expand and rupture. Recommended storage temperatures are 10° and 30°C (50° and 86°F). The polyol blend, Component B, is hygroscopic and should be protected from atmospheric moisture by sealing the container, or blanketing the product with a dry atmosphere. Component B is not phase stable and needs to be mixed thoroughly before and during use. Contamination with foreign materials, which can adversely affect processing, should be avoided. Materials should be stored at normal room temperature (18°-30°C).
