Material Glossary


Auto-Adhesive – When the surfaces of two heated pieces are brought together they weld. The strength of the weld will exceed the foam itself.

Brushed Nylon – Commonly laminated to foam-Velcro compatible.

Closed Cell – Impervious to penetration of liquid, gas or bacteria. Cleans easily. Will not breathe.

Compression Set – The ability or degree to which a material will resist “bottoming out” when subjected to a sustained load. Depends on magnitude or load, duration of loading, and the material itself.

Convoluted Foam – Coiled or having many complexly arranged elements, i.e. peaks and valleys.

Cotton Duck – A durable, closely woven, heavy cotton fabric, usually heavier than Sateen.

Cotton Duck w/Flannel Lining – Same as above with a brushed or slightly napped inner lining.

Cross Linked Polyester – A union of fibers and foams that molds
and holds shape.

Denim – A course twilled fabric, usually cotton.

Density – Thickness or consistency of a material.

Felt – A fabric of matted, compressed fibers, usually wool or fur.

Felt, Synthetic – A fabric of woven or knitted synthetic fibers, usually polyester or a combination of cotton and polyester.

Flame Lamination – The bonding together of a polyester foam to a substrate material, by using a gas flame to melt the foam into an adhesive condition and pressing onto the substrate forming a bond of the two materials (single lamination). You may use two material substrates with foam sandwiched between to form a bond of materials, which requires a second pass of the materials through the laminating machine (double lamination).

Foam Laminated – The single lamination of a substrate material to a foam.

Kodel – A synthetic woven or knitted fabric, usually of polyester
fibers (100%).

Laminated – Usually refers to the bonding of two or more materials to form one unit.

Muslin – Sturdy plain weave cotton fabric.

Neoprene – blended closed-cell material with either a single or double sided laminate.

Open Cell – Inherent property diverts moisture away from skin, wicks away.

Perforated / Ventilated – The adding of uniform spaced holes to allow for air passage.

Perforated Vinyl – laminated with cotton flannel.

Polyester Foam – A foam made of more than one synthetic resin and usually of a closed-cell structure, restricting air passage. When cut, this material always seals together temporarily, but will return to original shape if steamed, washed in hot water or pulled apart manually.

Polyethylene – A thermoplastic resin ideal for use in vacuum forming

Polyurethane – A grouping or family of foams known as ester and
ether foams.

Pressure-Sensitive Closure – For reasons of simplicity, this term is used to refer to any fabric closure used on soft goods, Velcro hook and pile, Velcro hook and Super Shur-Lok pile or Velcro Hook and other pile materials that engage to form a closure.

Reticulated Foam – An open-cell foam that allows for free passage of air or liquid and is commonly referred to as a filter foam.

Stockinette – An openwork, meshed fabric, usually cotton or nylon. Used as a covering to protect the skin from direct contact with foam or other coarse materials. Also used as a limb covering in orthopedic surgical procedures.

Substrate – A basic fabric used in lamination process, i.e. sateen,
cotton duck, etc.

Thermoplastic Moldability – Ability of material to be heated, then molded and retains shape of mold.

3-D Spacer Fabric – A three-dimensional knit spacer fabric that allows for easy flow of air and transfer of moisture.

Tricot – A weave of nylon & synthetic material.

UBL – Unbroken loop, which is brushed loop neoprene material with a nylon laminate.

Velcro – We use 8 mm. nylon monofilament hooks – 330 per square inch with peel strength of 7.9 average.

Vel-stretch – Loop or pile portion of Velcro that has stretching capabilities.

Volara – Hypoallergenic closed cell foam used to line splints.
