PUREstab 1330 has a good compatibility with most polymer substrates, high extraction resistance, odorless and excellent di-electrical properties. It reduces water carry-over in polypropylene tape extrusion. PUREstab 1330 is particularly recommended for polyolefin applications requiring good water extraction resistance combined with low color development. It can be used in combination with other additives such as costabilizers (e.g. thioethers, phosphites, phosphonites), light stabilizers and other functional stabilizers. The synergystic blends of PUREstab 1330 blend with PUREfos 168 is particularaly highly effective.
Applications & Uses

- Applications
PUREstab 1330 is a high melting antioxidant and used in polyolifins (PE, PP, PB) for the stabilization pipes, molded articles, wire and cables. PUREstab 1330 can also be applied in other polymers such as engineering plastics like linear polyesters, polyamides, and styrene homoand copolymers. It may also be used in PVC, polyurethanes, elastomers, adhesives, and other organic substrates.
In polyolefin’s, PUREstab 1330 is typically used in range from 0.05% to 0.3% depending on the substrate and processing conditions and long-term stability requirements. The optimum dosing is an application specific. The concentration levels range typically between 0.05% and 0.3% depending on substrate, processing conditions and stability requirements. In hot melt adhesives and synthetic tackifier resin, PUREstab 1330 concentration ranges from 0.2% - 1.0% and 0.1% - 0.5% respectively.
