Are the spectacle lenses people use now made of petroleum resin? Or are they made of natural resin? In fact,Petroleum Resin the problem is very simple, that is, everyone has made the simple problem a bit more complicated by rumors. It's not difficult to find that when we go online Baidu, in fact,Petroleum Resin lens resin and petroleum resin are very different.
The thermal polymerization of petroleum resin generally heats the carbon nine fraction to about 260°C in the reactor. First, it forms a Diels-Alder addition intermediate from two polymerizable molecules,Petroleum Resin and then reacts with another polymerizable molecule.
Carbon Nine Petroleum Resin is a thermoplastic resin obtained by splitting the by-product carbon nine distillate of ethylene plant into main raw materials,Petroleum Resin polymerizing it in the presence of a catalyst,Petroleum Resin or copolymerizing it with aldehydes, aromatic hydrocarbons, terpenes.
Hydrogenation modification, the C9 resin obtained by the polymerization reaction is generally darker,Petroleum Resin brown or brown thermal stability is poor, thus limiting the scope of application,Petroleum Resin through hydrogenation can destroy the unsaturated double bond in the resin, and remove the residual The halogen element,Petroleum Resin the modified resin is colorless and has no special odor.
As the global ethylene production capacity has improved year by year,Petroleum Resin because the by-product cracked carbon nine fraction of ethylene contains diolefins,Petroleum Resin aryl olefins and other components,Petroleum Resin the carbon nine petroleum resins obtained by the polymerization reaction are usually darker in color and have poor thermal stability.
In the past, petroleum resin companies had to rely on brick-and-mortar stores for market expansion if they wanted to improve their economic benefits. However,Petroleum Resin due to time and geographic constraints, the market expansion scope was limited.
