​What are the advantages and disadvantages of iridescent canisters?

Iridescent canisters have good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. In addition, iridescent canisters have good dielectric properties and environmental stress cracking resistance. Next, what are the advantages of iridescent canisters?


Here is the content list:

Introduction to advantages and disadvantages of iridescent canisters

First of all, iridescent canisters have good chemical stability, are insoluble in any organic solvents at room temperature, and are resistant to corrosion by acids, alkalis and various salts. However, iridescent canisters have low permeability to water vapor and air, and low water absorption; poor aging resistance and environmental cracking resistance are not as good as low-density polyethylene. In particular, thermal oxidation will reduce the performance of iridescent canisters. Therefore, iridescent canisters need to be added with antioxidants and ultraviolet absorbers to improve and improve this deficiency.High-density polyethylene film has a lower thermal deformation temperature under stress.This point should be paid attention to when applying iridescent canisters.


[Basic characteristics] The high-density polyethylene in iridescent canister is an opaque white wax-like material. Its specific gravity is lighter than water, and its specific gravity is 0.941~0.960. It is soft and tough, but slightly harder than LDPE, and is slightly stretchable, non-toxic. , Tasteless.


[Combustion characteristics] iridescent canisters are flammable and can continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. When burning, it will melt, dripping liquid, and no black smoke. At the same time, it emits paraffin wax. odor.


[Main advantages] iridescent canisters are resistant to acid and alkali, organic solvents, excellent electrical insulation, and can still maintain a certain degree of toughness at low temperatures. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.


[Main disadvantages] iridescent canisters have poor mechanical properties, poor air permeability, easy deformation, easy aging, easy to be brittle, less brittle than PP, easy to stress cracking, low surface hardness, easy to scratch. It is difficult to print. When printing, surface discharge treatment is required, no electroplating, and the surface is dull.


What are the main application advantages of iridescent cans?

High-density polyethylene resin can be used to form plastic products by injection, extrusion, blow molding and rotational molding. Various types of iridescent canisters containers, industrial accessories, medical supplies, toys, shells, corks and shields can be molded by injection molding. Blow molding can be used to form various hollow iridescent canisters containers, ultra-thin films, etc. Extrusion can be used to form pipes, stretch strips, straps, monofilaments, wire and cable sheaths, etc.


[Applications] iridescent canisters are used for extruding packaging films, ropes, woven bags, fishing nets, water pipes; injection molding low-end daily necessities and shells, non-load-bearing components, plastic boxes, turnover boxes; extrusion blow molding containers, hollow products, bottles .


[Injection molding process] HDPE has countless applications, ranging from reusable thin-walled beverage cups to 5-gsl cans, which consume 1/5 of domestic HDPE. iridescent canisters generally have a melt index of 5 to 10, and there are grades with toughness and lower fluidity and higher fluidity grades with processability. Uses include daily necessities and food thin-walled packaging; tough, durable food and iridescent canisters.


What are the benefits of recycling iridescent canisters?

For iridescent canisters for material recycling, PET plastic iridescent canisters are not only widely used for packaging carbonated beverages, drinking water, fruit juices, enzymes and tea beverages, etc., they are the most used beverage packaging today, and they are also widely used in food, chemicals, and medicines. Packaging and many other fields. The PET plastic in iridescent canisters has a wide range of applications in the packaging field. Both packaging film and roll materials use PET plastic.


On the other hand, the recycling of iridescent canisters can not only solve environmental problems, but also can be used as a new raw material resource to alleviate the contradiction of the shortage of PET raw materials in China. It can be seen that the recycling of PET iridescent canister is in line with the practical problems facing China, and is of great benefit to environmental protection, resource conservation, and sustainable development!
