What is the resin? Used to make tableware on the human body is not harmful?
You can do resin crafts, can not do the tableware resin is heated usually a softening or melting range, softening tendency to flow under the external force, room temperature is solid, semi-solid, sometimes can be a liquid organic polymer. Strictly speaking, is a chemical phenolic resin structure, there are many types, widely used in light industry and heavy industry in our daily life, we often come to, such as plastic, resin lenses, coatings, rosin.Any of a class of high molecular compounds that are soft and pliable. Generally amorphous solid or semi-solid. It can be divided into two categories: natural resin and synthetic resin. Rosin, benzoin is a natural resin, phenolic resin, polyvinyl chloride resin, synthetic resin. Resin is the main raw material for the manufacture of plastics, but also for the manufacture of coatings, adhesives, insulation materials, etc..There are natural resins and synthetic resins. Natural resin is an amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber, etc.. Synthetic resin is a kind of resin product which is obtained by chemical synthesis of simple organic matter or chemical reaction of some natural products.
There are many types of resins, the most widely used and the most widely used when the tree PVC resin, the resin is toxic, generally used in building materials, can not be used in food packaging or tableware! But the PVDC resin can be used for food packaging and so on, this is non-toxic, the most commonly used is the ham film! We plant these two resins are produced
There are two meanings, natural resins are also available, but we usually say that the resin refers to the plastic
Resin can not do tableware. We generally say that the resin refers to the plastic, it is best not to use tableware.Resin usually refers to the softening or melting range after heating, softening in the presence of external forces have a tendency to flow, at room temperature is solid, semi-solid, and sometimes can be liquid organic polymer. Broadly speaking, any polymer compound that can be used as raw material for processing plastic products is called resin.Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
