Thermoplastic polyurethane, with good tensile strength & elasticity, great resistance to oil, grease & abrasion and high mechanical properties, has been widely used in communication optical fiber like IEC & CPR flame retardant optical cable and special optical cable, etc. Technically, they are elastomers of linear segmented block copolymers composed of hard and soft segments. ATP's lszh and tpu materials Under the condition of high flame retardant performance, it still has excellent processing characteristics and high quality. The product fully meets the test requirements of the EU CPR EN50575 safety level (B2ca, Cca, Dca, Eca) After long-term repeated optimization of. TPU cables are encased in a unique thermoplastic polyurethane coating for greater bendability and durability. These include automotive charging cables, fiber optic cables and consumer electronic cables. As a specialized form of Industrial Cables, they combine armored protection, a durable TPU outer jacket, and stable fiber performance to support industrial. The jacket material determines the reliability, fire resistance, and lifespan of a fiber optic cable. LSZH (Low Smoke Zero Halogen) 3.
