The Kydex T sheet has a P3 velour matte texture and a red color, and meets UL 94V0 and 945V specifications for flame retardance. Kydex T is a tough, durable plastic that is easily formed and extruded. It offers high impact strength and abrasion resistance and is more resistant to impact and moisture than fire-retardant ABS/PVC (FR-ABS). One side has a P3 velour matte texture, and the other side is smooth. The P3 velour matte texture is less rough and less visible than a P1 haircell texture, but still provides mar and abrasion resistance. The textured side cleans with a soft cloth.

Plastic refers to a group of synthetic or semi-synthetic materials that have been engineered to achieve specific properties. The most notable characteristics of plastic are its low weight, machinability, corrosion resistance, and typically good thermal and electrical insulating properties. Depending on their properties, certain plastic grades can be used as alternatives to metal, glass, and ceramic. Some grades also offer optical clarity, a low-friction or self-lubricating surface, or exceptional impact resistance. Unlike metal, plastic may experience creep, which is deformation caused by longtime exposure to a constant load.

Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Impact resistance is the measure of a material’s ability to absorb a shock of energy before breaking.

Kydex manufactures thermoplastic sheets. The company, headquartered in Bloomsburg, PA, meets International Organization for Standardization (ISO) standards 9001 and 14001.
