Printing pp hollow sheet components

4MM good quality pp coroplast corona treatment

The pp  hollow sheet we usually use is not a pure material, it is made up of many materials. Among them high polymer polymer (or say synthetic resin) it is plastic main composition, in addition, in order to improve the performance of plastic, add all sorts of auxiliary materials in polymer even, wait like plasticizer, lubricant, stabilizer, colorant, ability makes the plastic with good performance.

 

Synthetic resin

Synthetic resin is the most important component of plastics, its content in plastic is generally 40% ~ 100%. Because of its large content and the properties of resins that often determine the properties of plastics, resins are often considered synonymous with plastics. For example, polyvinyl chloride resin and polyvinyl chloride plastic, phenolic resin and phenolic plastic confused. Actually resin and plastic are two different concepts. Resins are raw polymers that are used not only to make plastics, but also to make paints, adhesives and synthetic fibers. And plastic contains 100% outside very few resins, great majority of plastics, besides main component resins, still need to add other material.


plasticizer

Plasticizer can increase the plasticity and softness of plastics, reduce brittleness and make plastics easy to be processed and formed. Plasticizers are generally miscible with resin, non-toxic, odorless, light, heat stable high boiling point organic compounds, the most commonly used phthalates. When producing polyvinyl chloride plastic for example, if join more plasticizer to be able to get soft qualitative polyvinyl chloride plastic, if do not add or add plasticizer less (dosage <10%), get hard polyvinyl chloride plastic.

 

stabilizer

In order to prevent synthetic resin in the process of processing and use by the role of light and heat decomposition and damage, extend the service life, to add stabilizer in the plastic. Commonly used are stearate, epoxy resin and so on.

 

colorant

Colorants give plastics a variety of bright, beautiful colors. Organic dyes and inorganic pigments are commonly used as colorants.

 

lubricant

The function of lubricant is to prevent the plastic from sticking to the metal mold when forming, and to make the plastic surface smooth and beautiful. Commonly used lubricants are stearic acid and calcium magnesium salt.

 

antioxidants

Prevent plastic in heating forming or in the process of high temperature use by heat oxidation, and make plastic yellow, hair crack

 

In addition to the above additives, flame retardant, foaming agent, antistatic agent can be added to plastics to meet the different requirements of use.
