The study found that when the lead salt stabilizer is blended with other additives, it will react and generate a complex phosphate with extremely low solubility, which will significantly reduce the lead precipitation of the lead salt stabilized system.
Medical plastics have a broad market, and their performance requirements are generally relatively high, especially in terms of thermal stability, biocompatibility, drug compatibility, and environmental protection.
Since the 1980s, countries around the world have successively put forward requirements for prohibiting the use of lead salt and cadmium salt stabilizers: 1.
The stabilizer used to stabilize hard and soft polyvinyl chloride films is generally used in an amount of 0.5% to 3% of the amount of polyvinyl chloride. Due to the small amount, if used properly
1. The composite stabilizer has excellent thermal stability and weather resistance, as well as anti-oxidative light stabilization. 2. The internal and external lubrication of the composite stabilizer is balanced
Processing modifiers in the traditional sense almost specifically refer to modifiers used in the processing of rigid PVC to improve plasticizing properties, increase resin melt viscoelasticity and promote resin melt flow.
