IrgaCycle™ UV 033 DD is an additive composition of various stabilizer systems to improve durability and weathering properties of recycled polyolefins.

This product can be used to upgrade recycled material originating from short-life applications (such as packaging) for re-use in long-term applications and higher value applications. It is tailored for recycled LDPE, LLDPE, HDPE and PP for use in thick section articles such as bottle crates, containers, waste bins or pallets, for use in durable and outdoor applications.

Addresses the following recycling challenges:

• Depleted initial stabilizer packages
• Presence of pre-oxidized polymer chains and low molecular weight oxidation products

Depending on the residual stabilizer content of the recyclate material, IrgaCycle™ UV 033 DD is recommended in quantities from 0.1 to 1 %.

Features & Benefits

• Improves weatherability and extends service time
• Increases light and long-term thermal stability for improved durability
• Easy dosage during re-granulation or conversion steps
• Improved melt flow stability for better processing
