  • Maintains surface appearance over time
  • Compatible with various polymer systems
  • Supports durable and high-quality product design

Understanding the Mechanisms of Surface Damage

Surface damage in polymers occurs due to mechanical deformation and microstructural changes under stress.

  • Low surface hardness　makes materials more susceptible to scratching
  • Plastic deformation under load　leads to permanent surface damage
  • Stress whitening　caused by microvoid formation and light scattering
  • Inhomogeneous material structure　leading to uneven wear behavior
  • Insufficient energy dissipation　concentrates stress at the surface layer

These factors contribute to the visible degradation of polymer surfaces under repeated use.

Challenges of Surface Damage in Polymer Materials

Polymer components are widely used in applications where visual appearance and surface durability are critical. However, they are inherently susceptible to surface damage under mechanical contact.

Common challenges include:

  • Visible scratches caused by daily use or external contact
  • Surface whitening (stress whitening) after abrasion
  • Loss of gloss and aesthetic quality over time
  • Insufficient scratch resistance in conventional materials
  • Trade-offs between hardness, flexibility, and processability

These issues can negatively affect product value, customer satisfaction, and brand perception.

Polymer Alloy Technologies for Scratch Resistance

Our polymer alloy materials are engineered to enhance surface durability by optimizing the internal structure and mechanical response of the material.

Key technologies:

  • Controlled multi-phase morphology
  • Improved stress distribution within the material
  • Enhanced resistance to surface deformation
  • Balanced mechanical properties and processability

Performance concept:

Without Alloy Technology With Alloy Technology
Surface Damage Easy to scratch Improved scratch resistance
Appearance Visible whitening Reduced whitening
Surface Integrity Deformation occurs Maintained surface integrity

By improving internal structure, the material can absorb and distribute applied stress more effectively, reducing visible damage.
