DBLS (Dibasic Lead Phosphite) Heat Stabilizer Superior Protection
Slight white or light yellow,sweet and toxic powder with specific gravity of6.1 and refractive index 2.25.It can not dissolve in water, but can dissolve in hydrochloric acid and nitric acid.It turns to gray & black at 200°C it turns to yellow at 450°C and it has good deductibility.It is antioxidant it has the excellent performance of resistance to ultraviolet raycold and aging.
Features
Strong thermal stability: DBLS can effectively capture hydrogen chloride (HCl) during PVC processing, inhibit the dehydrochlorination reaction of PVC, and thus prevent PVC from being degraded due to heat. It can significantly increase the thermal decomposition temperature of PVC, so that it can maintain stable performance under high-temperature processing conditions, and reduce problems such as discoloration and mechanical property degradation.
Good weather resistance: In addition to thermal stabilization, DBLS can also absorb ultraviolet rays of a certain wavelength and has a certain light stabilization effect, which can enhance the weather resistance of PVC products, making them less likely to age, discolor and become brittle due to light when used outdoors for a long time.
Good electrical insulation: The stabilizer has good electrical insulation properties and will not have adverse effects on the electrical insulation properties of PVC products. Therefore, it is suitable for the manufacture of products with high electrical performance requirements such as wires and cables.
Excellent processing performance: DBLS has good compatibility with PVC and can be evenly dispersed in the PVC matrix during processing, which will not affect the processing fluidity of PVC and help improve the molding quality and production efficiency of products.
Applications
Mainly used for PVC soft and opaque products with good initial dyeing property,insulation and weather ability. Especially goes for outside cable board pipe etc.
Wires and cables: Due to its excellent thermal stability, electrical insulation and weather resistance, DBLS is widely used in the insulation layer and sheath materials of wires and cables. It can effectively protect wires and cables from the influence of heat, electricity, light and other factors during long-term use, ensuring their safe and reliable operation.
Rigid PVC products: In rigid PVC pipes, profiles and other products, DBLS as a heat stabilizer can improve the processing performance of PVC and the stability of products, making them have good mechanical strength, corrosion resistance and weather resistance, meeting the use requirements of construction, water supply and drainage and other fields.
Soft PVC products: For soft PVC films, sheets, artificial leather and other products, DBLS can provide good thermal stability and weather resistance while ensuring their softness, extending the service life of the products and improving product quality.
Precautions
Toxicity and protection: DBLS contains lead and has certain toxicity. During use, avoid inhaling dust or direct contact with skin and eyes. Operators need to wear personal protective equipment such as protective masks, gloves and goggles.
If it accidentally contacts the skin, rinse it with plenty of water immediately; if it enters the eyes, rinse it with running water or saline, and seek medical attention in time.
Storage conditions: It should be stored in a cool, dry and well-ventilated warehouse to avoid moisture and rain to prevent the product from absorbing moisture and deteriorating. At the same time, it should be stored separately from corrosive substances such as acids and alkalis to avoid chemical reactions.
Process control: During the PVC processing process, the amount of DBLS added should be strictly controlled and accurately measured according to the formula requirements. Excessive addition may cause the performance of PVC products to deteriorate, such as reduced transparency and poor mechanical properties. In addition, pay attention to the use of other additives to avoid interactions that affect product quality.
DBLS may decompose to produce a small amount of phosphorous acid at the processing temperature, so it is necessary to pay attention to the corrosion of the processing equipment and regularly inspect and maintain the equipment.
Environmental protection and waste disposal: Since DBLS contains heavy metal lead, its waste disposal needs to comply with relevant environmental protection laws and regulations. Waste DBLS and its packaging materials should be properly collected and handed over to professional environmental protection agencies for disposal. They must not be discarded or discharged at will to avoid environmental pollution.
After the PVC products produced using DBLS are discarded, they should also be recycled in accordance with environmental protection requirements to prevent lead elements from entering the environment.
