Plastics Application Fundamentals
* Polyethylene - its properties and uses.
Polyethylene is one of the most commonly used engineering plastics. Its chemical resistance properties and ease of fabrication makes it popular in the chemical industries. Its molecular structure provides the key to its versatility.
* Welding plastics.
Heat welding of plastics. Welding can join thermoplastic parts together. It can be by melting the surfaces and pressing them together or by extrusion welding with a filler rod. Several methods of welding are available. Proper manual techniques are critical to success as is the pressure testing of pressure parts.
* Fiberglass construction and repairs.
Fibreglass is a glass fibre reinforced plastic composite with excellent chemical resistance properties. Its physical properties, selection of resins and glass, method of construction and fabrication and peculiar repair requirements must be appreciated when using this material.
* Gluing Plastic Pipes so You Can Trust Them.
Adhesive joined plastic pipes have been known to separate at the glued joint. The joining of plastics using glue requires the glue to ‘hook’ into a clean, rough surface. The article explains the preparation procedure to use and the reasons behind its use.
