The materials come in four durometers: 80 Shore A (Elastollan M80A), 85 Shore A (Elastollan M85A), 88 Shore A (Elastollan M88A55), and 95 Shore A (Elastollan M95A55). The TPUs also resist abrasion, oil, fuels, and solvents.

Molding/extrusion compounds

ACRYLITE(R) df light-diffusing molding and extrusion compounds reportedly offer 20 to 40% more light transmittance versus pigmented products. The compounds obtain their special optical properties by incorporating spherical, high-molecular-weight polymer beads with a different refractive index into the acrylic matrix, changing the direction of light travel within the manufactured part. The compounds come in four concentra-tion levels: df20, df21, df22, and df23, and in standard S, H, M, and L grades.

Alloy

Alloy composition can be specified in atomic or weight percent, depending on specific requirements. The alloys can be melted under air, vacuum, or inert gas, and the range of compositions is virtually unlimited. Flake can be made by the splat-cooling process, in which a stream of molten alloy is poured on a rapidly spinning disc.

Hardfacing

Conforma CladTM proprietary hardfacing process applies tungsten carbide onto metal substrates by infiltration brazing. The resulting clad surface offers abrasion, corrosion, and erosion resistance. A degree of ductility gives the coating added toughness. The process creates high-density cloths composed of millions of precisely size-controlled particles of tungsten carbide and engineered alloys. The cloths attach to nearly any steel surface where protection is needed, without regard to line-of sight. When brazed, the resulting cladding becomes virtually 100% dense.
