Description

Riquit® Imported Anti-Aging Agent MX-535T delivers excellent UV protection for natural and pigmented polyethylene moldings with ASTM G155 weathering test performance ranging from 4000 to 16000 hours. Supplied as easy-to-handle, dust-free pellets, it helps resin manufacturers and molders reduce dust exposure, caking and feeding blockages.

• Outstanding UV protection (UV-8+) for long-service molded PE applications
• Good retention of mechanical properties
• Excellent color retention and surface protection for pigmented parts
• Low loading requirement and improved dispersion
• Very low color contribution for flexible color matching
• Superior gloss retention
• Improved recyclability
• Enhanced UV durability and better fastness & retention of pigments and physical properties
• Easy color formulation with low color development; REACH compliant and meets major food contact regulations
• Resistance to gas fading
• Approved under a wide range of food contact regulations
• Dust-free and easy for processing
• Improved operational efficiency with simplified inventory management

Anti-Aging Agent MX-535T is a cost-effective alternative that meets advanced market demands at a lower stabilization cost.

Compared with 944T, this product is a polymeric high-molecular-weight hindered amine light stabilizer (HALS). It features good heat resistance, extraction resistance, lower volatility and migration, as well as good compatibility with various resins. It performs exceptionally well in polyolefins and EVA agricultural films. It can also be used in melt-blown PP to improve electret performance. The required dosage of MX-535T is only half that of 944T and 2020T.

Its key advantage stands out for applications requiring multi-year aging resistance and high loading levels. When high dosages are needed, 944T and 2020T are difficult to incorporate into the formulation, while MX-535T shows obvious superiority under such circumstances.

MX-535T ensures reliable long-term protection for polyethylene injection and blow-molded articles at reduced addition rates. It meets critical performance requirements of injection and blow-molded polyethylene products, including crates, boxes, pails, storage bins, industrial containers, water tanks, waste bins, trolleys and toys. At similar loading levels to conventional HALS, MX-535T provides extra stability for molded parts, achieving up to 16000 hours in ASTM G155 weathering testing. When applied in flexible polyurethane foam sheets, it inhibits peroxide formation of polyols during storage and prevents scorching during foaming.

Application

The recommended dosage is 0.05%–0.5%, subject to the polymer grade and target performance of finished components.
