Polyethylene is a thermoplastic polymer with variable crystalline structure. It is massively produced (tens of millions of tons per year worldwide), and its extreme availability makes it one of the most easily affordable plastic materials on earth. Product Components Corporation offers a wide variety of fasteners and components in this popular material.
Polyethylene is manufactured in varying degrees of density, which results in its myriad applications. Low density polyethylene (LDPE) is used for everyday items such as grocery bags and plastic wrap, while High density polyethylene (HDPE) will find its way into harsher environments like construction (drain pipes and other plumbing, etc.). Ultrahigh molecular weight polyethylene (UHMW) goes even further on the performance scale, in high stress applications like internal medical devices and bulletproof vests! Polyethylene is also available is other, less commonly used sub-densities of the three aforementioned.
Advantages of the varying types of polyethylene include:
• High flexibility
• Unique flow properties
• High ductility
• Stiffness and strength in higher density, allowing it to contains liquids and withstand impact from sharp objects
• Superior tensile strength to steel in ultrahigh density
• Liquefication at extreme temperatures (rather than burning), making it ideal for recycling and re-use if necessary
• Non-toxicity in solid form, making it ideal in food handling applications
Other polyethylene applications include: milk cartons, laundry detergent containers, garbage cans, cutting boards, and it is the second most common choice for living hinges after polypropylene.
As for polyethylene fasteners, they are useful – at their varying densities – in all of the applications described above, i.e.: where insulation and impact resistance are paramount.
