1. High output rate:
Since the specific gravity of tin is about 1, the ratio of lead is significant (three-salt-based lead sulfate is 6.4, dibasic lead phosphite is 6.1), and lead is added in a large amount. At the same wall thickness, the organic tin system due to specific gravity is about 6% higher than the lead system.
2, excellent physical performance:
Profiles using organotin formulations have excellent physical and mechanical properties, especially improved weld bead strength and impact strength. According to the relevant information: the welding angle strength can be 10%-15% higher than other profiles. For example, when the tin formula is added with 8 parts of CPE, the weld angle strength is greater than 5000 N, and the tin formula plus acrylate Impact Modifier has a weld angle strength of 6000N-8000N. Excellent impact resistance, even American profiles with wall thickness of 1.8mm-2.0mm have good impact resistance.
3, good weather resistance:
The 1000-hour aging results of the organic tin profiles of Qinhuangdao Longchen Group showed that the notched impact strength before aging was 52.8KJ/M2, 41.2 KJ/M2 after aging, and the color change after aging was grade 4. Hu Xingjun, Senior Engineer of the Institute of Synthetic Materials Aging, Ministry of Chemical Industry, pointed out in the article "Durability of Polyvinyl Chloride Profiles" that any profile containing lead salt stabilizer system is prone to discoloration after photoaging and pollutes the product after 1500 hours of illumination. After significant yellowing; the sample containing the tin-Tin Stabilizer system did not change significantly after the same illumination. For many years, plastic doors and windows using organotin formulations have been used extensively in the desert regions of the United States, and the results are good, which is a powerful example. In the use of profiles in coal-fired areas, lead salts are easily reacted with sulfur dioxide in the air to become gray.
4, the number of joins is small:
The addition of 0.9 parts of the machine tin stabilizer can replace all lead system stabilizers. Due to the higher price of the organotin stabilizer, the formulation cost is slightly higher than the lead salt formula.
5, lead-free and non-toxic, green and environmentally friendly:
The use of lead-free formula is undoubtedly a good thing to protect the environment, protect workers' health and benefit future generations.
6, excellent plasticity, easy to operate and reduce energy consumption:
The plasticity of the tin formulation can make up for the defects of poor plasticity and low shearing force of some devices. It can also be said that the tin formulation has adaptability to various devices. Generally, the temperature of each part of the tin formula processing is 7-10 ° C lower than that of the lead system, which reduces the energy consumption.
7, excellent surface gloss:
The profile produced by the organotin formula has a smooth and lustrous appearance and a delicate touch such as grease.
