Identifying plastics for plastic welding

Identifying plastics

  1. In most plastic parts on the back will be a symbol symbol.This says what type of plastic welder is working. (If not displayed is then you will need different welding rods to see if the rod will keep the plastic)
  2. This is a very important step because for plastic welding filler metal should be the same as the plastic being welded. (Unless you use the fiber-flex rod, but the stick only comes in black)
  3. There are two families of thermosetting plastics 1)) and two thermoplastic
  4. Thermoset "You can not be melted and reused.
  5. Thermoplastics can be melted, and reuse

Symbol table

Thermoset PLASTIC

  • PUR, RIM, RRIM "These tend to be flexible. Bubble melted.When smoke when welding the base material does not melt! Melt welding rod into the slot at V as a hot melt.

THERMOPLASTIC

  • -ABS (acrylonitrile-butadiene styrene) – rigid, can be any color, used in plastic interior parts of cars, trucks and also articles household sweepers parts, handles of pots and so on.
  • Commission on the Limits "(Ether Ester Block Copolymer) – Flexible, off white. Better to use Uni-Weld fiberflex.
  • EMA-() ethylene-methacrylic acid semi-rigid, comes in many fiberflex colors.Use Uni-welding.
  • -PA (polyamide (Nylon)-rigid finely.Used sand in tanks on the radiator, headlight bezel, exterior trim parts, mirror.
  • PULSE-PC + ABS () polycarbonate and ABS-rigid usually dark, sand finely.Preheat plastic welder before welding.
  • PC + PBT-(Xenoy a mixture of polycarbonate) "Very rigid.Used for covers.Preheat plastic bumpers welded before welding.
  • PE-()-semi-flexible polyethylene, melt and smear usually crushed in semi-translucent.Used overflow tanks, interior panels, fenders, bumpers ATV. The application of filler or painting is impossible.
  • PP-()-polypropylene semiflexible melts and smears when grinding.
  • + PA-PPO (Noryl GTX (nylon blend))-semi-rigid, usually whitish in color.car fender and the outer edge. Plastic welding preheat before welding.
  • -TEEE (Thermoplastic Elastomer Ether Ester) – Flexible, used on the bumpers, panels. Use fiberflex welding rod.
  • TPE-()-semi-flexible thermoplastic elastomer, it melts and slides for grinding. It is used bumper covers, under the Uni-Bell parts.Use Fiberflex welding rod.
  • TPO, TEO, PP/EPDM- () olefin-semi-flexible thermoplastic melts and smears when grinding. Used in Gilles interior parts, snowmobile cowls.Use Fiberflex Uni-welding rod.
  • TPU, TPUR-()-thermoplastic polyurethane flexible, fine sand. Bumper covers, soft filler panels. Use the bar or a bar of uni-weld urethane Fiberflex.

In general, the elements have most of the house are the abdominals, but if you're not sure you need to do a test in plastic welding. Be sure to take the test. When you will not be able to see so that is not in their part and make work more (as sanding and ect.) As always take care

soldering iron is hot and can cause burns or fire!
