Customer Reviews
FEIYANG did offer their professional services and products to us. That is why we have had a long-term and stable business with them for several years. Nowadays, we are more like partners instead of just one of their distributors. Also, I hope we can expand markets in the future together.

—— USA Distributor

Feiyang is a reliable supplier, not only their product quality but also their professional technical support and service. We have done business together for six years already, which contributed to the growth of our business from nothing to several containers annually. We are so happy and lucky to have Feiyang as our partner.

—— European Distributor

We are very happy to be one of Feiyang's distributors in Australia. They are pretty nice supplier. They always do their best to meet our requirements. Our customers also trust Feiyang's high-quality product and out-standing service. Looking forward to developing more business together.

Latest company news about What is the difference between natural and synthetic resin? What is polyaspartic resin?

Resin plays a very important role in our life, our common perception of resin is the natural resin products of trees and other plants and animals, but in fact, synthetic resins are also very widely used in our life. So what is the difference between natural resin and synthetic resin?


What is resin?

Resin is defined as an organic polymer that has a softening or melting range when heated, has a tendency to flow under external force when softened, and is solid, semisolid, or sometimes liquid at room temperature. Broadly speaking, any polymeric compound that can be used as a raw material for the manufacture of plastic products is called a resin. Depending on the source of the resin, it is classified as either natural or synthetic.


Difference between natural resin and synthetic resin

1. Different definitions

Natural resin usually refers to the natural metabolic products or secretions of plants and animals, such as amber, colophony, wormwood, and so on.

Synthetic resin refers to the resin products obtained by chemical synthesis of simple organic substances or by chemical reaction of certain natural products.


2.Different sources

Natural resins are derived mainly from plant exudates (urine) of amorphous semisolid or solid organic matter.

Synthetic resin is synthesized from a polymer.


3. Different characteristics

Natural resins become soft when heated and can be melted, have a tendency to flow under stress, are generally insoluble in water, soluble in alcohols, ethers, ketones and other organic solvents. This type of material is a variety of sources derived from plants, mainly rosin lacquer, amber and so on. Derived from animals, mainly wormwood, it is the secretion of the purple gum worm. Natural resins can also be categorized according to the resin components and the history of resin formation. According to the basic components of resin can be divided into three categories: ① Pure resin, that is, by the terpenes and crude essential oils composed of resin-like substances. Generally insoluble in water, but soluble in organic solvents such as rosin. ② gum resin containing gum resin, which is composed of polysaccharide substances, soluble in water or water-soluble but insoluble in organic alcohol solvents, such as incense. 3 aromatic resin containing oil resin, refers to the resin containing more essential oils that can be dissolved in oil. According to the formation history of the resin can be divided into fossil resin, semi-fossil resin and fresh resin. The latter is the main source of natural resins. Some natural resins are named after the ports where they were first collected for export, such as Coba resin.

Synthetic resin is a viscous liquid or a solid that can be softened by heating, usually has a melting or softening temperature range when heated, and can enter a plastic flow state under the action of external force, and some of its properties are similar to natural resin. Synthetic resins are not only the main raw material for manufacturing plastics, but also the basic raw material for manufacturing synthetic fibers, paints, adhesives, insulating materials and so on. There are many types of synthetic resin. According to the main chain structure classification of carbon chain, heterochain and non-carbon chain synthetic resins. According to the classification of synthetic reaction characteristics of polymerization and polycondensation type synthetic resins. The production of synthetic resins from a variety of sources of raw materials, the early coal tar products and calcium carbide acetylene-based, now more oil and natural gas-based products, such as ethylene, propylene, benzene, formaldehyde and urea. Synthetic resin production methods using body polymerization, suspension polymerization, emulsion polymerization, solution polymerization, melt polymerization and interfacial polycondensation.


Polyaspartic polyurea resins are a class of synthetic resins. polyaspartic polyureas are coatings that contain urea linkages formed by reacting the secondary amine group on the polyaspartic resin with isocyanate. As an industrialized high-performance material, polyaspartic polyurea resin has a wide range of applications. At present, it is mainly used as the main resin of coatings, applied to waterproof coatings, anti-corrosion coatings, floor coatings, industrial coatings and other fields. It can also be applied to seam sealants, potting compounds, adhesives, casting materials and other fields.
