Applications

EXP BLS® 3346 is a highly effective light stabilizer in polyolefins in both thick- and thin-section applications, including polypropylene, polyethylene, olefin copolymers, and TPOs.

Advantages

• Highly effective as a light stabilizer in plastics, in both thin and thick sections
• Provides enhanced long-term thermal oxidative stability in polyolefins
• Non-discoloring, low volatility, excellent resistance to extraction and migration
• FDA compliant

Guidelines for Use

Suggested use levels range from 0.1 to 1% by weight. The exact recommendation depends on the substrate, processing conditions, and the nature of the end-use application. Combinations of EXP BLS® 3346 with other light stabilizers, such as HALS, UV absorbers, and benzoates, often show synergistic performance. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Please contact your Mayzo representative for specific
recommendations for your application.
