Individual Heat Stabilizers
Single-compound lead stabilizers and co-stabilizers — TBLS, lead stearate, dibasic lead stearate, dibasic lead phosphite and dibasic lead phthalate — for compounders who build their own formulations.
Tribasic Lead Sulphate (TBLS)
Powerful non-lubricating primary heat stabilizer — stable at elevated temperature without decomposition, so finished products stay sound and free of porosity.

Lead Stearate (LS)
Lubricating co-stabilizer — greater lubricity than DBLS with better dispersion thanks to its lower melting point, giving rigid and flexible PVC a smooth surface.
View product →
Dibasic Lead Stearate (DBLS)
High free-lead co-stabilizer plus high-temperature lubricant — it does not melt under normal service conditions, enabling long, fast production runs.
View product →
Dibasic Lead Phosphite (DBLP)
Heat stabilizer and primary light stabilizer — excellent UV and weathering resistance with retention of physical properties after ageing.
View product →
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).
