UBL fabric - An unbroken loop material that engages hook fasteners.In addition to our premium grade loop fastener fabric, we also offer intermediate and economy grades.

UL 94 HF1 - Underwriters Laboratory. The 94 is a specification for testing the flammability of plastic materials used for parts in devices and appliances. The HF-1 test is intended to be performed on foamed plastic materials. Other tests include 94 HBF, 94 V-O and 94 5-V

Under cure - For cellular rubber, when the time period in which various chemical reactions occurring (e.g. cross-linking) does not last long enough. The result is a loose cell structure, a mushy appearance, etc. This problem is most apparent in the center of a material and this area will often collapse after skiving.

UV Stabilizer - Any chemical compound which, when mixed with a resin, selectively absorbs UV rays. Since UV wavelengths are shorter than the visible, their photons have more energy, enough to initiate some chemical reactions and to degrade most plastics.
