UVnox
UV Stabilizers (HALS & UV Absorbers)
Outdoor exposure causes polymer degradation, loss of mechanical strength & fading. UVnox UV Stabilizers protect polymers from harmful UV rays.
BASIC:
- Prevent fading & loss of gloss
- Reduce brittleness & cracking
- Improve outdoor lifespan & weather resistance
ADVANCE
- Used for automotive parts, outdoor cables, films, fibers, rotomolding, tanks
- HALS + UV absorber synergy recommended for high exposure
- Testing: QUV, Xenon Arc weathering, tensile retention, gloss retention
