Material Information

Material Info

Unlike our competitors (who offer one material), Flex Trim provides our flexible molding solutions in four different material formulations in order to accommodate every application. The below information provides a detailed description of each of the materials that we offer but please Click Here to see a detailed comparison chart of each.

Flex Trim™
Flex Trim is our original flexible moulding product. It is a unique polymer resin blend and is the ideal solution for most standard flexible moulding applications. Although it is less expensive than ZzzzFLEX, Flex Trim still exceeds the performance of our competitors’ “high end” products.

ZzzzFLEX is our premium product and is state-of-the-art in flexible moulding technology. No other flexible moulding on the market is stronger, more durable of stains better than ZzzzFLEX. ZzzzFLEX is an elastomer composite developed for the most demanding and complex radius applications. It offers flexibility that is unsurpassed by any other flexible moulding and is the ideal solution for cold weather climates because it is more pliable. Use ZzzzFLEX for small intricate patterns and tight curvatures, or when only the best will do.

Ultra-Flex is a syntactic polyurethane compound with a cellular composition structure similar to wood. One of the main advantages of this material is that it 40-50% lighter than other flexible moulding formulations, yet retains the necessary strength and durability that customers have come to expect. It is an ideal solution for very large moulding profiles and the light weight also saves on freight costs. Unlike other flexible moulding materials, Ultra-Flex is PRE-PRIMED for superior painting and staining and is “back sanded” for better glue adhesion. It works great for both interior and exterior applications and has outstanding performance in cold and hot climates. MANUFACTURED ONLY IN OUR UTAH FACILITY but available nationwide.

Machinable S4S
Our Ultra-Flex compound can be machined with all conventional woodworking machinery and will not dull expensive carbide knives like other flexible products. It can be used with shapers, routers and moulders to avoid the expense of custom tooling and is the ideal solution when only a small amount of STRAIGHT footage is required. Machinable S4S is available in straight lengths only and can be run in any dimension required with the following limitations:

  • Maximum of 2 inches thick, 16 inches wide, and 12 feet long.
  • Minimum of 1 / 2 inch thick, 1-3/4 inches wide, and 8 feet long
  • Stain grade patterns can not be used because the “grain” is only on the surface.

There are no set up charges and all S4S blanks are wide belt sanded to match millwork standards. MANUFACTURED ONLY IN OUR UTAH FACILITY but available nationwide.

Adjustable Mold


Ultra-Flex’s adjustable mold produces STRAIGHT S4S blanks, in any dimension up to a maximum of:


  • 2 inches thick, 16 inches wide, 18 feet long
  • No set up charges for straight S4S custom size blanks
  • All S4S blanks are wide belt sanded to match millwork standards
  • Use for short runs to match your custom wood profiles
  • Excellent for Extended Jamb stock or Radius Arch Jambs
