The global fast charging technology is accelerating its iteration, and the charging power of mobile phones, notebooks and other devices has exceeded 200W, but traditional charging cables have become the "Achilles' heel" of user experience due to problems such as heat generation and easy breakage. PVC slingshot cable (telescopic charging cable) is being upgraded from an "accessory" to the core component of the fast charging ecological chain with its anti-stretch, high rebound and aging resistance characteristics. According to the "2025 Consumer Electronics Wire White Paper", the annual growth rate of the slingshot wire market will reach 22%, of which PVC substrates account for 65% of the market share due to the balance between cost and performance.
Technical pain points and innovative breakthroughs
High-current carrying revolution:
The diameter of the tin-plated copper conductor has been upgraded from 0.08mm to 0.12mm, the resistivity has been reduced to 0.017Ω/m, and it supports 100W PD fast charging (temperature rise ≤ 15°C);
The double-layer shielding structure (aluminum foil woven mesh) suppresses electromagnetic interference and has a data transmission rate of 480Mbps (USB 2.0 standard).
Multiplication of bending life:
The coil spring structure is covered with 304 stainless steel TPE, and the tensile life exceeds 20,000 times (the industry average is 8,000 times).
The wire body is added with Kevlar tensile fiber, with a tensile strength of 200N to avoid internal copper core breakage.
Environmental Compliance Upgrades:
Lead-free PVC formulation is RoHS 2.0 and REACH certified, with a phthalate content of <0.1%;
Degradable TPU coating material has been successfully developed, with a natural decomposition rate of ≥ 90% in 180 days.
A mobile phone brand has measured that after using PVC slingshot wire:
the after-sales maintenance rate decreased by 53%, saving more than 8 million US dollars/year;
In the user satisfaction survey, the "durability" score increased to 4.8/5;
The carbon footprint of the product is reduced by 30%, and it has received extra points for EU green procurement.
