l What material is HDPE?
l Advantages of HDPE neckerchief
HDPE is an opaque white waxy material with a specific gravity of 0.941~0.960, which is lighter than water. It is soft and ductile, but slightly harder than LDPE and can be elongated.It is non-toxic and tasteless. It is the product of polymerization under low pressure catalyzed by Ziegler catalyst,so high density polyethylene is also called low pressure polyethylene.
The unique characteristics of various grades of HDPE are the appropriate combination of four basic variables:density,molecular weight,molecular weight distribution and additives.Different catalysts are used to produce customized polymers with special properties.These variables are combined to produce HDPE grades for different purposes;Achieve the best balance in performance

High density polyethylene resin can be used by injection, extrusion, blow molding and rotary molding plastic products. Injection molding can be used to form various types of containers, industrial accessories, medical supplies, toys, shells, bottle stoppers and guards and other products. Blow molding can be used to form all kinds of hollow containers, ultra-thin films, etc. Extrusion molding can be formed pipe, stretching strip, binding belt, monofilament, wire and cable sheath, etc.
In addition, it can also be used for building decoration board, shutter, synthetic wood, synthetic paper, synthetic film and molding calcium plastic products.
1.HDPE has excellent resistance to most domestic and industrial chemicals.It can resist the corrosion and dissolution of strong oxidants,acid-base salts and organic solvents.
2.HDPE is non hygroscopic and has good water vapor resistance.It can be used for moisture-proof,anti-seepage or packaging.
3.HDPE has good electrical properties,especially high insulation dielectric strength,which makes it very suitable for wires and cables.Medium to high molecular weight grades have excellent impact resistance,even at room temperature and-40F low temperature.
4.HDPE has good processability and heat sealing.
5.HDPE is highly paper like,crisp and open,and its hardness is 4~5 times that of LDPE film.Its surface hardness,tensile strength,rigidity and other mechanical strength are close to PP and tougher than PP.
6.HDPE is non-toxic and odorless.It can also be used in food,clothing,knitwear and other packaging materials.It is economical,applicable and cheap.
7.It’s convenient to use.you don’t need spend time washing it, it's convenient when your time are fully occupied or you just don't have that mood to do cleaning
8.It also can keep your clothes clean.It is made of HDPE material, the HDPE material is lightweight, waterproof and not easy to tear, keeping your clothes clean and tidy when you are having your hair dyed.
The above introduces the HDPE material and the material characteristics and advantages of HDPE hair dyeing bib, the information provided is more detailed, please refer to, hope to provide some help for buyers to buy hair dyeing bib.
