What type of raw material for plastic straw?
The main component of plastics is resin. The term was first resin secrete by animal and plant lipid and its name, such as rosin, shellac, resin is not mixed with various additives and polymer compounds. Resin accounts for about 40% to 100% of the total weight of plastics.
The plastic is made of monomers as raw materials, polymer by polyaddition or polycondensation polymerization (macromolecules), commonly known as plastic resin (plastics) or (resin), can freely change the composition and form style, composed of synthetic resin and filler, plasticizer, stabilizer, lubricant, pigment and other additives.
The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role. Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene. The so-called plastic, in fact, it is a kind of synthetic resin, the shape of the natural resin with pine resin similar to, through chemical means of artificial synthesis, and is called plastic.
