Polyurethane, or PUR for short, is a highly developed, halogen-free thermoplastic elastomer. Five advantages of PUR cables PUR has five major advantages over the regularly used sheath materials polyethylene (PE), polyethylene with flame-retardant.

OCC's line of tactical fiber optic cables for deployable applications has always provided the most rugged and flexible method to deploy fiber over harsh terrain where a typical fixed cable installation is not possible. The polyurethane jacket on our deployable cables provides resistance to crush. What are the characteristics of polyurethane cables? Polyurethan (PUR) - Thermoplastic Elastomere (TPE) PUR stands for "polyurethane" (VDE Designation “11Y”). The insulation and sheathing material "PUR" is a thermoplastic elastomer (TPE) and has become increasingly important in the cable industry. Optical fiber coatings/buffers play an important role in protecting the fiber from its intended environment. The primary coating may be applied in a single or dual layer. The product fully meets the test requirements of the EU CPR EN50575 safety level (B2ca, Cca, Dca, Eca) After long-term repeated optimization of. Thermoplastic polyurethanes (TPU) are a class of polyurethane plastics with many exceptional properties including elasticity, high tear strength, and resistance to oil, grease and abrasion. Technically, they are elastomers of linear segmented block copolymers composed of hard and soft segments.
