Hot sale high-strength resin folding chair

Resins are divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances derived from the secretions of animals and plants in nature, such as rosin, amber, shellac, etc. Synthetic resins refer to resin products obtained by chemical synthesis of simple organic substances or chemical reactions of certain natural products, such as phenolic resins, polyvinyl chloride resins, etc., among which synthetic resins are the main components of plastics. The relative molecular weight is uncertain but usually high. It is a solid, medium solid, pseudo-solid, and sometimes liquid organic substance at room temperature. It has a softening or melting temperature range, has a tendency to flow under the action of external force, and is often shell-shaped when broken. Broadly refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water but soluble in organic solvents. According to the source, it can be divided into natural resin and synthetic resin; according to the different characteristics of its processing behavior, it can be divided into thermoplastic resin and thermosetting resin. ABS resin is a copolymer of acrylonitrile-butadiene-styrene, and its English name is Acrylonitrile-butadine-styrene (abbreviated as ABS). Plastics and ABS alloys are the main modified plastics with large output, various types and wide applications.

ABS is a light yellow granular or bead-like opaque resin, non-toxic, odorless, low water absorption, and has good comprehensive physical and mechanical properties, such as excellent electrical properties, abrasion resistance, dimensional stability, chemical resistance and surface gloss, etc. And easy to process and shape. The disadvantages are weather resistance, poor heat resistance, and flammability. The development of folding chairs As folding chairs themselves have become popular seats, there have been diversification of forms and production processes. Because folding chairs no longer contain too many symbols of power and dignity, this has also led to the development of new functions and new designs. At the end of the 19th century, folding chairs were already designed by utilitarians, and seats of various forms and purposes appeared. Folding chairs have a long history of military use. It needs to have a straightforward and compact appearance, and meet the characteristics of durability. When it begins to show aesthetics, people will have memories of it. But it has never been designed beautifully.
