Ethylene Vinyl Acetate (EVA) copolymers are versatile materials used in a wide range of applications, from footwear and adhesives to films and foams. However, like many polymers, EVA is susceptible to degradation when exposed to UV radiation and heat. This can lead to a loss of flexibility, discoloration, and reduced mechanical strength, compromising the product's performance. To combat this, advanced light stabilizers are essential. NINGBO INNO PHARMCHEM CO.,LTD. offers Light Stabilizer 944, a highly effective Hindered Amine Light Stabilizer (HALS) that significantly enhances the durability of EVA copolymers.

The Challenge of UV Degradation in EVA

The vinyl acetate content in EVA can influence its susceptibility to photo-oxidation. UV exposure can initiate radical chain reactions, breaking down the polymer structure. This degradation can manifest as brittleness, surface cracking, and yellowing, particularly problematic for applications where aesthetics and flexibility are key, such as films, coatings, or molded components.

Why Light Stabilizer 944 is Ideal for EVA Copolymers

Light Stabilizer 944 is a high-molecular-weight, oligomeric HALS that provides robust protection against UV light and thermal degradation. Its specific advantages for EVA applications include:

  • Superior Light Stabilization: It effectively scavenges free radicals formed by UV exposure, thereby protecting the EVA matrix from chain scission and oxidation. This translates to extended product life and retained performance characteristics.
  • Excellent Extraction Resistance: The high molecular weight of Light Stabilizer 944 means it is highly resistant to being leached out of the EVA by solvents, moisture, or during washing cycles. This ensures the stabilizer remains in place, providing continuous protection.
  • Low Volatility: During the processing of EVA (e.g., injection molding, extrusion, or foam production), our Light Stabilizer 944 exhibits minimal volatilization. This preserves the additive content, prevents equipment fouling, and contributes to a safer working environment.
  • Broad Applicability: While excellent for EVA, its compatibility extends to other polymers like PP, PE, polyamides, and polyurethanes, making it a versatile chemical auxiliary agent for compounders.
