Exempel på hur man kan använda LDPE i en mening

• These are important building blocks for the production of essential polymers (LDPE, HDPE, PP) and like other chemical intermediates are currently produced mainly from petroleum feedstock.
• Traditionally used packaging films like LDPE (low-density polyethylene), PVC (polyvinyl chloride), EVA (ethylene-vinyl acetate) and OPP (oriented polypropylene) are not permeable enough for highly respiring products like fresh-cut produce, mushrooms and broccoli.
• Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.
• Multi-use water bottles can be made from high-density polyethylene (HDPE), low-density polyethylene (LDPE), copolyester, or polypropylene.
• LDPE has more branching (on about 2% of the carbon atoms) than HDPE, so its intermolecular forces (instantaneous-dipole induced-dipole attraction) are weaker, its tensile strength is lower, and its resilience is higher.
• The copolymerization process produces an LLDPE polymer that has a narrower molecular weight distribution than conventional LDPE and in combination with the linear structure, significantly different rheological properties.
• More than 80% of all the material used is from the polyethylene family: crosslinked polyethylene (PEX), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), and regrind.
• From these differences in polymerization type the distinction originates between low-density polyethylene (LDPE), high-density polyethylene (HDPE) or even ultra-high-molecular-weight polyethylene (UHMWPE).
• From the 1960s onward in the United States, with improvements in shipping and storage materials, glass bottles have almost completely been replaced with either LDPE coated paper cartons or recyclable HDPE plastic containers (such as square milk jugs), depending on the brand.
• Crosslinking technology is used in the formation of EVA based foams, including LLDPE, LDPE, HDPE, PP, and TPE.
• The shelf life of pasteurized milk in HDPE bottles and LDPE pouches has been determined to be between 10 and 21 days when stored at 4–8 °C.
• The complex consists of low-density polyethylene (LDPE), high-density polyethylene, polyphenol, olefin, ethylene oxide/ethylene glycol and ultrasonic testing plants.
• Biopolymer coatings are available as more sustainable alternatives to common petrochemical coatings like low-density polyethylene (LDPE) or mylar.
• One approach in the field involves the conversion of waste plastics (like LDPE, PET, and HDPE) into paramagnetic, conducting microspheres or into carbon nano-materials by applying high temperatures and chemical vapor deposition.
• Rigid-shell plastic containers, including polyethylene terephthalate (PETE #I), high-density polyethylene (HDPE #2), low-density polyethylene (LDPE #4), polypropylene (PP #5) and polystyrene (PS #6), which previously contained a non-hazardous consumer product.
• Polymers commonly crosslinked using the electron-beam irradiation process include polyvinyl chloride (PVC), thermoplastic polyurethanes and elastomers (TPUs), polybutylene terephthalate (PBT), polyamides / nylon (PA66, PA6, PA11, PA12), polyvinylidene fluoride (PVDF), polymethylpentene (PMP), polyethylenes (LLDPE, LDPE, MDPE, HDPE, UHMWPE), and ethylene copolymers such as ethylene-vinyl acetate (EVA) and ethylene tetrafluoroethylene (ETFE).
• Renewable polyethylene is non-biodegradable and can be recycled in the same waste streams as traditional polyethylenes (HDPE, LDPE, LLDPE) as it is chemically identical.
• PE (polyethylene) of various densities, also abbreviated to LDPE, MDPE and HDPE (low, medium and high density polyethylene; the medium density version is at times referred to as "black alkathene" in the UK).
• Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE).
• Polymers such as EVA or LDPE can be used as carriers for polyolefins and nylon, while polystyrene can be used for ABS, SAN, and sometimes polycarbonates.
