RCS News5/13/13 High Power EMKs Being Added to Store
We have decided to add a complete line of high power Experimental Motor Kits (EMKs) to the RCS store, ranging in size from from 29/60 to 98/15360. They will be added as time permits, over a several week period. Check the EMK category for regular updates.

Featured Products
54mm Nozzle, 0.455" Throat
Molded glass/phenolic nozzle for 54mm diameter motors. Dimensions: 1.985" O.D. 0.455" diameter throat 1.250" diameter exit Click here for drawing$27.50
200 Micron Ammonium Perchlorate Oxidizer
Standard grade rotary rounded 200 micron AP w/TCP (hazmat and extra shipping charges apply). 20 pound pail.$129.99
Copper Chromite Catalyst
Copper Chromite is a proprietary blend of copper and chromium oxides, black in color, and is a moderate burn rate catalyst which finds use in endburning and medium-to-high burn rate compositions. Typical concentration level is 0.5 - 3.0% of propellant weight. 100 gram jar.$19.95
Desmodur E 744 Isocyanate Curative
Desmodur E 744 Isocyanate is an excellent room temperature curative for HTPB. It provides plenty of pot life and good physical properties. If you've been using PAPI or Isonate 143-L you'll be amazed at the difference! Use at the 13.1% concentration level with R-45HTLO with an OH value of .85 (hydroxyl equivalent weight of 1176.5). For the mathematically...$13.75
Isodecyl Pelargonate Plasticizer
In our opinion, Isodecyl Pelargonate (IDP) is the best plasticizer for HTPB-based binders. Its low density, low viscosity, low vapor pressure and cure retardant properties will give you a noticeable improvement over DOA, DBP or whatever else you've been using. 10-35% of the total binder percentage is the usual concentration. 8 ounce bottle.$13.75
R-45HTLO Polybutadiene Resin w/CAO-5 Antioxidant & HX-752 Bonding Agent
R-45HTLO polybutadiene resin premixed with 0.95% CAO-5 antioxidant and 2.38% HX-752 bonding agent. This premix should be used for propellants that contain 400 micron or larger Ammonium Perchlorate, or whenever maximum propellant strength is desired. HX-752 is unique among the commonly-used bonding agents in that it does not release Ammonia during propellant...$62.45
R-45HTLO Polybutadiene Resin
We've chosen to offer R-45HTLO instead of R-45M for a number of reasons. It has a slightly higher functionality, which results in a higher crosslink density with the better room temperature curatives (like E 744 described below), without resorting to other ingredients that can adversely affect the cure chemistry. It also allows you to use higher percentages...$62.45
Phenolic Motor Liner, 54mm Kosdon
Spiral-wound paper/phenolic liner for 54mm Kosdon motors. Dimensions: 1.915" O.D. 1.835" I.D. 25.97" long$6.25
