Reticulated (like a net) Polyester Urethane foam, more expensive than Polyether, provides a much higher degree of performance, durability, and consistency. Lightweight, resilient, excellent vibration dampening and insulation properties. It also offers high resistance to chemicals and moisture.

Polyether urethane foam is softer, with superior resistance to moisture, and is better for cushioning in wet conditions than polyester. If you need more tensile strength and support, the polyurethane ester foam is better.

Polyethylene foam is a highly refined grade of material that is mainly used for high-quality packaging. Its molecular structure is very linear which makes it very tough, highly flexible and pliable with great tear strength.

Black lightweight gator board is made from a dense foam core sandwiched between two rigid sheets of wood-fiber veneer. Water and weather-resistant, and will not easily break or warp, yet the direct sun may harm it without special protection.

A lightweight gator board is made from a dense foam core sandwiched between two rigid sheets of wood-fiber veneer. This exterior is everlasting -water and weather-resistant, and will not easily break or warp.

Ultra lightweight, Foam Core is comprised of extruded polystyrene foam with clay-coated white paper facers. Not waterproof. Indoor use only. No grommets or drilled holes is recommended - the material is too soft..

Slightly glossy foam rubber, light-weight, odorless, strong at low-temperatures. UV, water, stress-proof. Softer and lighter than high-density EVA. Less expensive than natural rubber.

Ultra-dense EVA foam rigid sheets - anti-static, smooth on both sides, lightweight, tear-resistant, can be heated, molded. More rigid, stiff, and durable than low-density EVA. Compared to polyethylene, the vinyl acetate makes EVA more rubbery, and elastic.

Light (floating), very flexible, with high elasticity. Best shock-absorbing qualities. Highly durable, sturdy, withstands strong forces, weather-resistant, and is able to withstand some other harmful agents such as fuel oils and chemicals. Production is made easy and similar to thermoplastics.

Hot-compressed two times, EVA foam creates a more condensed material - phylon. It preserves the lightweight and softness of EVA while gaining better abrasion properties, higher flexibility in terms of cushioning, and the ability to define the finest details of the design. More expensive than EVA.

Expanded Polyethylene (EPE), light-weight semi-rigid foam. Shock resistance better than EPS; low surface water absorption; good penetration resistance; acid, alkali, salt, oil and other organic solvents , Excellent aging resistance; no flowing at high temperature, no brittleness at low temperature.

Expanded Polypropylene (EPP), the fastest-growing new type of environmentally friendly compression buffer insulation foam. Very tough. Not easy to break. High recovery rate after deformation, very good heat, chemical, oil resistance, and heat insulation.

Expanded polystyrene (EPS) or Styrofoam, is a light-weight rigid, tough, closed-cell foam. Good thermal insulator. Permeable by water (bad vapor barrier), in case of water logging, loses its insulating properties., and if water freezes, the form can break. Less expensive of all foams. Colors vary.

A lightweight gator board is made from a dense foam core sandwiched between two rigid sheets of wood-fiber veneer. This exterior is everlasting -water and weather-resistant, and will not easily break or warp. Comes in white or black - see sellers for the details.

High-density foam, light in weight, gives a lot of volume at a low price, the silky-smooth surface is hard to finish well because it is so easily damaged. Very low dent resistance. Cuts easily by hand. For quality, cost-effective dimensional foam letters, use Gatorfoam.

Precision board with a silky-smooth surface, lasts10X longer than wood, waterproof, eco-friendly. Will not rot or decompose at any climate changes. Significantly less expensive than 18lb board. Slightly lower abrasion resistance and machine surface finish smoothness.

Wood substitute. Density 18lb is similar to redwood or cedar. A premium extremely smooth precision board, waterproof, weatherproof, lasts 10X longer than wood, with higher abrasion resistance. High level of edge detail.

Aluminum substitute. A high-density precision board perfect for CNC tooling with significant tool life and high levels of small detail. Expensive, but cheaper and faster to machine than aluminum.

More expensive than same density HDU. Less expensive than aluminum. Great for masters in metal casting for quick and accurate prototypes. Tough enough to last through a few rounds of metal stamping in the home shop. Unaffected by the chemicals, heat, and vacuum.
