Introduction to TPE Sheets
The mainstream TPE sheet extrusion equipment adopts a continuous production process of single-screw extrusion + three-roll calendering + cooling traction + rewinding. The core features are uniform plasticization, precise thickness, stable cooling, and a smooth surface.
Common Quality Problems and Causes of TPE Sheet Equipment
Uneven Thickness: Improper die lip adjustment, unstable three-roll gap, extrusion pressure fluctuations
Rough Surface or Crystal Points: Insufficient plasticization, clogged filter, raw material impurities
Bubbles or Silver Threads: Moist raw material, degradation due to excessive temperature, poor venting
Warping or Deformation: Uneven cooling, unstable traction tension, high internal stress
Color Difference: Uneven masterbatch dispersion, temperature fluctuations, unstable recycled material ratio
Applications of TPE Sheets
TPE sheets have a wide range of applications. Their core characteristics are softness, elasticity, environmental friendliness, non-toxicity, and recyclability.
Footwear & Sporting Goods
Shoe sole pads, insoles, shoe linings
Sports protective gear pads, wristbands, wrist straps
Diving material composite TPE anti-slip layer
Building Materials & Engineering Applications: Expansion joint overlap strips, waterproof sealing gaskets; Floor sound-absorbing pads, sound-absorbing buffer sheets; Pipe sealing, waterproof membrane surface layer.
