Description

Riquit® Anti-Aging Masterbatch MX-5050H is a high-efficiency light stabilizer, also known as hindered amine light stabilizer (HALS). It is mainly applied in various polymers to prevent degradation triggered by ultraviolet radiation.

● LDPE: MX-5050H delivers excellent light stability in films and thin-wall articles. Recommended dosage: 0.1–1.2%

● For PP fibers, MX-5050H provides outstanding light stability. In thick automotive parts made of PP copolymer resin, MX-5050H shows excellent light and thermal stability either used alone or synergistically with other light stabilizers. MX-5050H features low water carry-over or no water carry-over during water cooling for PP film products. For reference, the recommended dosage is 0.20–0.50%.

● HDPE: MX-5050H achieves good light stability for both thick and thin articles. Recommended dosage: 0.1–0.5%

● Nylon: A 1:1 blend of MX-5050H and UV-4050 offers remarkable light stability for nylon fibers.

● ASA: A 1:1 blend of MX-5050H and UV-3035 can significantly improve the thermal stability, light stability and weather resistance of ASA.

Summary: The loading level depends on the target light stabilization performance of the resin and shall be determined by tests for different resin systems. When MX-5050H is used together with sulfur-containing stabilizers (such as thiodipropionate or thiophenol anti-aging agents), antagonistic effects may occur. The same applies to sulfur-containing or halogen-containing pigments and pesticides, which are critical for agricultural films. This rule is also applicable to halogenated flame retardants.

Advantages

● Produced via a special granulation process for easy feeding, accurate dosing, uniform dispersion and excellent storage stability. ● The active ingredient is not prone to blooming at high temperatures. The masterbatch remains dry and non-tacky on the surface with excellent anti-caking performance. ● Great compatibility, which substantially reduces blooming and chalking. It shows prominent synergistic enhancement with other high-molecular-weight hindered amine light stabilizers. ● Non-blooming and non-tacky; convenient for transportation, storage, feeding, dosing and dispersion. The active content of the masterbatch can be tested rapidly. ● Dust-free and easy for processing.

Application

Recommended dosage: approximately 0.1–1.2%, depending on the required performance of the polymer and finished components.
