9/29/16 Low Molecular Weight Hydroxyl-terminated Polybutadiene Resin Now Available
RCS low molecular weight Hydroxyl-terminated Polybutadiene (HTPB) resin has an unusually low viscosity as a result of a molecular weight of only 1,300. Its corresponding low equivalent weight naturally allows the use of a higher percentage of isocyanate, which results in a substantially reduced premix viscosity. In addition, lower plasticizer percentages can be employed to increase propellant toughness, while maintaining processability. OH values are typically 1.80 (equivalent weight 556); the measured value is printed on the container label. Sold in 1 gallon and 1/2 gallon bottles.

7/20/16 New Restrictions on AP Purchases
Due to increased Department of Homeland Security (DHS) concerns, we we are placing new restrictions on all Ammonium Perchlorate (AP) purchases. Effective immediately, all purchasers of AP must have a Tripoli Rocketry Association (TRA) L2 or higher certification on file with RCS, or provide evidence that they are a legitimate business, government or academic customer.
