Dibasic Lead Phthalate (DBLPh)
High-temperature heat stabilizer for demanding flexible PVC — the choice for heat-resistant cable insulation and compounds that must survive sustained heat ageing. Distinct from DBLP (phosphite).
Overview
Dibasic lead phthalate (DBLPh) is a separate product from dibasic lead phosphite — different chemistry, different job. Where DBLP protects against light and weathering, DBLPh is prized for high-temperature performance: strong heat stability and excellent resistance to heat ageing, which makes it the stabilizer of choice for high-service-temperature flexible PVC such as heat-resistant cable insulation. Detailed grade specifications are available on request.
