Use I]
Used as heat stabilizer in PVC rigid transparent products
[Use II
This product is a heat stabilizer for PVC, with excellent heat resistance and transparency, no sulphur pollution, long-term heat resistance is particularly good, can prevent the products from turning yellow during high temperature processing. It is particularly suitable for hard and transparent products, and its high melting point does not reduce the softening point and impact of hard products. The general dosage is 0.5-2%. The use of barium soap or cadmium soap has a synergistic effect and can further improve the stabilising effect. The product lacks lubricity and has poor processing properties; it is volatile; it sometimes blisters during processing; and, under the action of hydrogen chloride generated when heated, it translocates to fumarate, which is less compatible with the resin and prone to frosting. To overcome these shortcomings, a number of modified varieties have been developed.
Use III]
Catalyst for condensation. Gasoline explosion-proof agent. Heat stabilizer for polyvinyl chloride (PVC), with excellent heat resistance and transparency, no sulphur pollution, particularly good long-term heat resistance, prevents products from turning yellow when processed at high temperatures.
