Paraffin manufacturers will explain to you the reasons why fully refined paraffin has reversible deformation. The high flash point and low volatile content of fully refined paraffin oil provide better weather resistance and small volatile properties at high temperatures for the processing of rubber and thermoplastic elastomer products. White wax oil has the characteristics of low volatile content and high flash point. Low aromatics content. This is particularly important in the application of peroxide curing technology, and the low aromatics content can reduce the consumption of curing agents, and then reduce the cost. The low aromatic hydrocarbon content and low volatility of white lab-based oil are far better than other rubber filling oil that is not fine, and improve the antioxidant degradation function of rubber and elastomer, low volatility helps to prevent aging and shortening, and is conducive to improving the poor appearance of the finished product (such as rough, there are bubbles), both of which are conducive to extending the service life of the finished rubber. Very low content of dense aromatic hydrocarbons, dimethyl sulfoxide extract content is much less than 3%, do not need to be labeled carcinogenic tendency, harmless to human health and the environment.

Fully refined paraffin oil is a mixture of naphthene as the primary component, so special waxes do not have a consistent molecular formula, but can only be represented by a representative model. Naphthenic oil is mainly composed of one or more full ring carbon chains, which are connected with a number of branch chains. The naphthenic oil we can get today is from the natural mineral oil - naphthenic crude oil. Only a small amount of cycloalkanes come from artificial synthesis, such as cyclohexane from the hydrogenated product of benzene, but benzene is simply from petroleum, so the origin of naphthenic oil is made by special naphthenic crude oil processing. Because the rubber oil produced by naphthenic oil has irreplaceable advantages over the rubber oil produced by other petroleum, it has been greatly developed. Wing Loong brand naphthenic rubber oil, through nearly 20 years of development, gradually formed four series of commodities, if according to the time they put into the market to be different, they are YT series, K371 series, KN series, KNH series.

The structure of rubber is linear structure, branched chain structure and crosslinked structure, which are three kinds of structures. Rubber is a highly elastic polymer material with reversible deformation. Elastic at room temperature, in very small. It can produce large deformation under the action of external forces, and can be restored to the original state after removing external forces. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, the molecular weight is often large, greater than hundreds of thousands. Natural rubber is a natural polymer compound with polyisoprene as the primary component, the molecular formula is (C5H8)n, 91%~94% of its composition is rubber hydrocarbon (polyisoprene), the other is protein, fatty acid, ash, sugar and other non-rubber substances. Natural rubber is a widely used universal rubber.
