SperseStab™ 1425 is a high-molecular-weight phenolic antioxidant containing a phosphonate located para to the phenol. This orientation provides excellent color and low gas fading in a UV-stabilized antioxidant. The calcium salt acts as a soluble catalyst, especially for the esterification of rosin esters. Additionally, SperseStab™ 1425 works as a catalyst in the solid-state polymerization of PET polymers. Other applications include polyolefins, fibers, adhesives, and lubricating oils and greases.

SperseStab™ 5153 is a mid-weight hindered amine light stabilizer with excellent permanence and compatibility with various filled systems, including carbon black, talc, CaCO3, Mg(OH)2, and others. This cost-effective product is ideal for roofing membranes, exterior packaging, and machine parts. The use of filled systems is becoming increasingly popular due to their structural, economic, and processing advantages. SperseStab™ 5153 can be used alone or in combination with other additives, including antioxidants, hindered amine light stabilizers, and UV absorbers. Other potential applications include filled nylon systems with SperseStab™ 5153 alone or in conjunction with other antioxidants.
