#802: Industrial parts, prototypes, exterior signs, mixes good with M15 and HG3000 fillers. Good for making decorative parts only if painted 100% due to  lingering odor of plastic.
#555: Similar to #802 but is more resilient. Lingering odor.
#891: Good for making small decorative items such as mini refrigerator magnet decor, dolls, miniature cars or models, no odor. Add our fillers to achieve different physical properties.  Also refer to ROTO-ONE for a longer gel time.
#709: Use for making mass cast parts with our fillers to make Machineable plastic for thermoforming tools, patterns, holding fixtures. No odor.
#SA90: Shore A 90 flexible rubber for semi-hard rubber wheels, bumper guards, unbreakable cast plaques.
#SA50: Shore A 50 flexible rubber for bumper guard, cement casting mold.
#ROTO-ONE: Rigid open pour or rotational molding resin.  A little longer gel time and stronger physicals. If you need more time to pour, try this one. Off white.
#TUFF CAST: Very strong impact resin for making bowling balls or other castings where you do not want them to chip or break easily.  White, no odor.
