What WPC additives enhance resistance to damage from fireworks fallout?

Wood-Plastic Composites (WPC) are widely used in outdoor applications due to their durability and aesthetic appeal. However, exposure to fireworks fallout can cause surface damage, discoloration, and structural weakening. To enhance resistance, specific WPC additives are incorporated during manufacturing.

1. Flame Retardants: Additives like aluminum trihydroxide (ATH) or magnesium hydroxide reduce flammability and minimize damage from sparks or embers.

2. UV Stabilizers: Hindered amine light stabilizers (HALS) protect against UV degradation caused by prolonged exposure to firework residues.

3. Impact Modifiers: Elastomers or rubber-based additives improve toughness, preventing cracks from debris impact.

4. Anti-Oxidants: Phenolic or phosphite antioxidants prevent oxidative degradation from chemical residues in fireworks.

5. Water Repellents: Silane or wax additives reduce moisture absorption, preventing swelling or warping from firework chemicals.

By integrating these additives, WPC products achieve superior resistance to fireworks fallout, ensuring longevity and performance in high-exposure environments.
