Additives

UV Absorbers

IOur UV stabilisers are liquid blends of UV absorbers and antioxidants developed to offer improved UV and heat resistance to all PU and TPU applications.

Key benefits:

  • Strong effectiveness in UV absorption
  • Excellent thermal stability
  • Excellent antioxidant activity
  • Easy to handle, no dust
  • Safer working conditions
  • Compatible with ether and ester-based PU systems
  • Easy blending with polyol
  • Low viscosity
  • Can be added to REPI colours for a ready-to-use solution

Antistatic additives

The occurrence of electrostatic charges is a major challenge in the production of polyurethane, especially in hazardous areas or in the electronics industry.

PU parts can accumulate electrostatic charge and dust. Repi antistatic additives are specially designed to improve conductivity properties of PU and TPU soles.

Repi materials allow you to create soles that constantly discharge electrostatic charges to the ground, obtaining ESD certification.

Key benefits:

  • Excellent electrical conductivity
  • Excellent thermal, mechanical and electrochemical stability
  • Compatible with ether-and ester-based polyurethane systems 
  • Easily mixed with polyol
  • Low viscosity

Anti-hydrolysis additives

They help to preserve and slow down the degenerative process of hydrolysis of polyurethane.

Optical Brightneres

Optical Brighteners are organic additives that absorb ultraviolet light and re-emit most of the stored energy in the visible spectrum, giving polyurethane applications a brighter and fresher appearance.

Key benefits:

  • Excellent brightening effect 
  • Improved colour rendering 
  • Compatible with ether-and ester-based polyurethane systems 
  • Easy blending with polyol 
  • Low viscosity
