Rare Earth Composite PVC heat stabilizers advantages
2013-08-14 by seoer8
Pvc heat stabilizer in the process, a single-component process stabilizer is to meet the demand. The rare earth pvc heat stabilizer heat stabilizers to play the maximum effect, and only through, and other compound stabilizers for PVC composite can be achieved. According to processing needs, technical support, the type of product, as well as the ratio of the different conditions, the synthesis of rare skin thermal stabilizer is different. Currently on the market of rare earth compound PVC heat stabilizer generally have the following seven advantages:
1, excellent thermal stability. Rare earth stabilizer either dynamic or static thermal stability are superior to the traditional system and lead salts of barium, cadmium, zinc stabilizer in products to replace or reduce the use of organic tin products. Development prospects of 2, to promote melting, good processing performance. Rare earth metal salt is added stabilizer may change the rheological properties of materials, and to promote the melting of the organic tin performance close.
3, coupling compatibilization. Rare stabilizer for PVC products, coupling of each component has a unique compatibilization, can improve the impact strength of products, can promote the increase of the amount of the resin filler.
4, plasticized, toughening. Rare earth metal salt stabilizers and stabilizer compared to a plasticizing the resin, toughening effect.
5, excellent transparency. Dilute ten stabilizers either alone or in combination with organic tin product mix, the optical performance can be organic tin products the same effects when used alone.
6, brightening properties. Rare earth stabilizer used in colored plastic, with a clear and unique brightening functions.
7, the weather resistance. Rare earth stabilizer significantly better anti-aging effects of light on the lead salt stabilizer, organic tin performance equivalent to seven additional stabilizer thin insulating properties and also excellent in safety and hygiene.
