01 | Material Overview: What is high density polyethylene?<\/span><\/h1>\n

 <\/p>\n

High density Polyethylene (HDPE) is a thermoplastic made by polymerization of ethylene. It is noted for its high crystallinity and linear structure.Compared with low-density polyethylene (LDPE), the molecular chains of HDPE are more compact and less branched, giving it higher strength, chemical stability and heat resistance. <\/span><\/p>\n

Typical performance parameters include:<\/span><\/p>\n

\u00a0 \u30fbDensity range:<\/strong> 0.941-0.965 g\/cm\u00b3<\/span>
\n\u00a0 \u30fbThe tensile strength<\/strong> is as high as 31 MPa<\/span>
\n\u00a0 \u30fbOperating temperature range:<\/strong> -40\u00b0C to 120\u00b0C<\/span>
\n\u00a0 \u30fbOutstanding chemical resistance and electrical insulation performance<\/strong><\/span><\/p>\n

Due to these characteristics, HDPE is widely used in multiple fields such as piping systems, food packaging, household containers, automotive fuel tanks, and medical-grade products.<\/span><\/p>\n

04 | Technological innovation: a new direction for High density polyethylene material upgrading<\/span><\/h2>\n

 <\/p>\n

\u2714 copolymerization modification of HDPE<\/span><\/strong><\/p>\n

By introducing copolymer monomer (such as butene or hexene), the toughness and environmental stress cracking resistance of HDPE can be adjusted, especially suitable for fuel storage tanks, pressure pipes and other high stress scenarios.<\/span><\/p>\n

\u2714 Inorganic filler enhancement<\/span><\/strong><\/p>\n

The addition of fillers such as calcium carbonate and talc powder can enhance the dimensional stability and rigidity of HDPE, which is used in injection molded trays, medical grade syringe parts, etc.<\/span><\/p>\n

\u2714 ultraviolet resistance and antibacterial modification<\/span><\/strong><\/p>\n

Facing the outdoor or medical market, HDPE is combining with additives such as UV stabilizers and nano-silver to make antibacterial water pipes, hospital classified garbage cans, and sun exposure packaging products.<\/span><\/p>\n

06 | Veelgestelde vragen (FAQ)<\/span><\/h1>\n

 <\/p>\n

Q1: What are the differences between HDPE, LDPE and LLDPE<\/a>?<\/span><\/strong><\/p>\n

A: HDPE has the highest crystallinity, strength and rigidity far better than LDPE and LLDPE, which are suitable for hard containers and structural parts, while the latter two are more flexible and suitable for film and flexible packaging.<\/span><\/p>\n

Q2: HDPE can be used for food packaging?<\/span><\/strong><\/p>\n

A: Yes, food-grade HDPE<\/a> conforming to FDA and EU food contact regulations can be used for milk bottles, bottled water, dairy packaging, etc., but you need to choose the certified raw material model.<\/span><\/p>\n

Q3: HDPE materials can be recycled?<\/span><\/strong><\/p>\n

A: HDPE is one of the best recyclable plastics. After recycling, it can be made into pipes, pallets, non-food grade packaging containers, etc., to achieve closed-loop use.<\/span><\/p>\n

Q4: How can I tell if a certain HDPE is suitable for my device?<\/span><\/strong><\/p>\n

A: It is suggested that combined with MFI, density grade, processing temperature window and other parameters, we can provide samples and processing suggestions to facilitate rapid verification.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
