WebIt is sometimes called "alkathene" or "polythene" when used for HDPE pipes. [1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code . WebHigh-pressure polyethylene processes are characterized by high reaction temperature (150-300oC) and pressure (1,000-3,000 atm). Two types of processes are commonly used: a tubular process using a very long, small-diameter tubular reactor and an autoclave process using a well-stirred tank reactor. It is well known that
WebThe molecular weight continues to rise over an Al/Ti ratio of 2.0, however, the weight average remains constant. The Ziegler process produced a high-density polyethylene at pressures as low as atmospheric pressure. High-density polyethylene is a more durable polymer when compared to low-density polyethylene due to its lower degree of branching. WebHigh pressure polyethylene LDPE, also known as high pressure polyethylene, is produced at pressures ranging from 82—276 MPa (800—2725 atm). Operating at 132—332°C, it may be produced by either a tubular or a stirred autoclave reactor.
WebLDPE is produced at high pressure (1000-3000 bar) and temperature (80-300°C). It is derived via the free radical polymerization process. ... How to process PE plastic?
