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.
Resin. It is a hydrocarbon (hydrocarbon) secretion from various plants,Petroleum Resin especially coniferous plants. Because of its special chemical structure and can be used as this latex paint and glue,Petroleum Resin it is valued. It is a mixture of multiple polymer compounds, so it has different melting points. Resin can be divided into two kinds of natural resin and synthetic resin. There are many kinds of resins,Petroleum Resin which are widely used in people's light industry and heavy industry. They are also often seen in daily life, such as plastics, resin glasses, and paints. Resin lenses are lenses that have been chemically processed and polished using resin as a raw material.
Petroleum resin. There are two types of petroleum resins we are most in contact with: 1. C5 petroleum resin 2. C9 petroleum resin. Petroleum resin is actually a newly developed chemical product in recent years. Due to its advantages of low price, good miscibility,Petroleum Resin low melting point,Petroleum Resin water resistance, ethanol resistance and chemicals,Petroleum Resin it can be widely used in rubber, adhesives, coatings, paper, ink And many other industries and fields.
The answer can be obtained from the above two definitions. The material used for the lens of the glasses is called resin. There are natural and chemical synthesis. The latter chemical synthesis is actually derived from petroleum and synthesized, but this does not mean that this type of The resin is called petroleum resin. Don't confuse audiovisual here. Let's take a look at petroleum resins. Products made of petroleum resins generally have no requirements on the light transmission effect. According to the characteristics of the target product,Petroleum Resin the material of petroleum resins is determine
