Calcium zinc heat stabilizer for transparent polyvinyl chloride infusion tube

Heat stabilizers can effectively prevent PVC from degrading due to heat and mechanical shearing during the manufacturing process of polyvinyl chloride medical infusion tubes. They can also prevent PVC products from being damaged by heat, light, oxygen, etc. during use, so as to maintain their physical properties and extend their service life. Calcium zinc heat stabilizers are the most widely used type of stabilizer in the field of PVC medical infusion tubes due to their environmental protection, good thermal stability and high cost performance. However, the use of calcium zinc heat stabilizers can easily lead to a generally high zinc content and reducing substance content in PVC medical infusion tubes, which may even exceed the limit value.
