PE SHEET KS-6600
Polyethylene has the simplest molecular structure due to its sequence of CH2 segments. The result is a long-chain molecule with few branches. Depending on the manufacturing process, polyethylene can be produced with high density (PE-HD) and low density (PE-LD).
These variants differ in the number of branches to be found in the material, which in turn reflects the degree of crystallinity. The smaller the number of branches, the higher the crystallinity because molecules can become attached to one another very densely on account of inner forces of attraction. Rising crystallinity also means higher density and a higher crystallite melting range.
LOW DENSITY POLYETHYLENE (LDPE)
LDPE, was the first of the polyethylene¡¯s to be developed. It is a corrosion resistant, low density extruded material that provides low moisture permeability. LDPE has a fairly low working temperature, soft surface and low tensile strength. It is an excellent material where corrosion resistance is an important factor, but stiffness, high temperature and structural strength are not important considerations.
Features
Lightweight, Formable, Impact Resistant, Excellent Electrical Properties, Machinable, Weldable.
Fabrication
LDPE can be fabricated using the following techniques. Hot gas welded, Fusion and butt welded, Ultra-sonic sealed, Die cut, Vacuum formed Thermo-formed, Machined with wood or metal working tools.
Applications
Chemical resistant tank and containers, Food storage containers, Laboratory equipment Disposable Thermo-formed products, Corrosion resistant work surfaces, Vacuum Corrosion resistant work surfaces, Vacuum formed end caps and tops, Moisture barriers.
