Stabilizers Have A Wide Variety Of Combinations
The meaning of stabilizers:
1, broadly speaking, can increase the solution, colloid, solid, the stability of the mixture of chemical compounds are called stabilizers. It can slow down the reaction, keep the chemical balance, reduce the surface tension, prevent the light, thermal decomposition or oxidation decomposition and other effects. The broad range of chemical stabilizer sources is very extensive, mainly according to the design purpose of formula designers, Stabilizer can flexibly use any chemical to achieve product quality stability purposes.
2, narrowly speaking, mainly refers to maintain the polymer plastic, rubber, synthetic fiber and other stability, prevent its decomposition, aging reagents.
Stabilizer is a kind of auxiliary material which can inhibit the decomposition of PVC resin at high temperature, Stabilizer prolong the service life of PVC products or prevent and restrain the influence of various factors in the working environment of PVC products.
Stabilizer includes heat stabilizer, light stabilizer, antioxidant and mildew inhibitor.
Stabilizer and its different combinations are various, in order to better grasp its cutting properties and characteristics, must be classified. In the existing classification methods, Stabilizer the most obvious is based on its chemical composition to classify, followed by its thermal stability, optical stability, electrical and used in hard or soft products transparent or opaque, toxic or non-toxic and so on different conditions for classification.
Usually, the stabilizer is divided into four types: lead salts, metal soaps, organotin and epoxy esters. Lead salts can be divided into salt-based lead and general salt. Metal soaps are mainly stearic acid metal soap and can be divided into lead soap, barium soap, paving soap, calcium soap and zinc soap and so on. Stabilizer Organic tin is also a variety of, such as the lauric acid two Butyltin series, maleic acid butyltin system and mercaptan tin system. The secondary stabilizer is epoxy ester, chelating agent and so on.
Stabilizer is widely used in food, medical treatment of various PVC (PVC) Packaging processing and other industrial plastic materials processing. 1928 is a general-purpose environmental protection heat stabilizer, with excellent initial coloring performance and long-term stable performance. Stabilizer The product application of special formulations to strict technical management, advanced production process control, so that its thermal stability, weather resistance and safety performance is superior to other organotin stabilizers, particularly suitable for the manufacture of high property PVC products.
Product Features: The product has a high color transparency, a very weak odor, not easily volatile, the quality of durable and stable, is the production of high transparency, environmental protection type calendering, extrusion, granulation, blown film, such as high-quality, Stabilizer high quality PVC processing products, the preferred heat stabilizer.
