PVC and PUR are commonly used outer sheaths for cables, and even without instruments, we can still quickly distinguish between these two materials by mastering these methods.
1.Touch
PVC: plastic, smooth surface and high hardness.
PUR: closer to rubber elasticity, soft and tough.
2. Bending springback
PVC: there will be slight creases after bending, and the rebound is slow.
PUR: easy bending, fast springback and almost no trace left.
3. Scratch test
Ordinary PVC: it is easy to leave marks when the nails are lightly scratched.
High performance wear-resistant PVC: the surface is compact and the scratch resistance is significantly improved.
PUR: extremely hard to
4. Incision observation
PVC: the cut is dense and shiny.
PUR: the incision is Matt, with a sense of elastic fiber.
5. Weight comparison
Cables of the same specification:
Heavier PVC
Lighter PUR
