The high molecular weight makes it a very tough material, but results in less efficient packing of the chains into the crystal structure as evidenced by densities of less than high-density polyethylene (for example, 0.930–0.935 g/cm 3). UHMWPE can be made through any catalyst technology, although Ziegler catalysts are most common.
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] 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. [6]
When UHMWPE is annealed, the material is heated to between 135 and 138 °C (275 and 280 °F) in an oven or a liquid bath of silicone oil or glycerine. The material is then cooled down to 65 °C (149 °F) at a rate of 5 °C/h (9 °F/h) or less. Finally, the material is wrapped in an insulating blanket for 24 hours to bring to room temperature.
The most commonly used Uncured Elastomers are Chlorosulfonated Polyethylene (CSPE), Chlorinated Polyethylene (CPE), Polyisobutylene (PIB), Nitrile Butadiene Polymer (NBP). Thermoplastics (e.g. PVC, TPO) – Plastic sheets welded together with hot air, creating one continuous sheet membrane. Lends itself well to both big box and small roof ...
BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation. [1] When metallized, it has [3] gas and moisture barrier ...
Medium-density polyethylene (MDPE) is a type of polyethylene defined by a density range of 0.926–0.940 g/cm 3. [1] It is less dense than HDPE, which is more common. MDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts. MDPE has good shock and drop resistance properties. It also is less notch ...
