Addition of heat stabilizer stops the formation of free hydrogen

　　PVC is commercially known as Poly Vinyl Chloride and as we all know is used in various commercial products like cables, clothing, fuiture, construction industry, etc. The product is not suitable to use for commercial purpose in its original form. The chemical compound present in the original product is capable of reacting with sunlight, heat and other natural agents. Chlorine being the main component many hazardous effects is also associated with it. It is also difficult to use PVC in its original form because of its brittleness. It was observed that adding some chemicals make the original product resistant to the natural agents. These additives act as a stabilizer and make PVC usable. These PVC stabilizers increase the strength of the Flower Pot Machine polymer and increase its value for commercial use. The PVC stabilizers also help in reducing its harmful effect.

The Use of PVC Stabilizers PVC stabilizer makes it resistant to oxidation and increases the shelf life of the polymer. PVC is commonly known as Vinyl in most part of the world and is composed of mainly chlorine and carbon. The fact that PVC does not require crude oil or gas for its production it is considered as a natural resource which replaces the use of plastic and in some cases rubber also. PVC consumption and its demand are very high because of its compatibility with other products. It is used widely in every type of product. PVC is known to have low stability towards heat and hence heat stabilizers are used to increase its resistance towards heat. The use of heat stabilizers in PVC helps to process it at high temperatures. The presence of chlorine in PVC is the main reason behind its degradation due to high heat. It was found out in a chemical reaction that once free hydrogen chloride molecules are formed in the polymer the degradation process becomes a chain reaction and continues with time.

Addition of heat stabilizer stops the formation of free hydrogen chloride molecules and stops the degradation chain reaction. The stabilizer has to be added before the PVC is subjected to high heat because adding it later in the process will not be effective in stopping the chain reaction. Types of PVC Stabilizers There are different types of PVC stabilizers used in the industry. Lead based stabilizers have been used for a long time since these are economical and give high thermal stability of the polymer. These stabilizers are used for preparing PVC for electrical cables etc. Metal soaps stabilizers are second types of stabilizer used widely.

The effect is same as the Lead based stabilizer but it provides short-term stability to the polymer. These stabilizers are widely used for PVC utilized in the food industry because they are non-toxic. New researches are being carried out to find stabilizers which are non-toxic and also provide long term stability to PVC. Mike Funes invites you to take a look at Kyungsan Petrochem. These PVC Stabilizers increase the strength of the polymer and increase its value for commercial use. The PVC stabilizers also help in reducing its harmful effect.
