PLASTICS RECOGNITION
The first step in creating a successful weld, is determining which plastic you
are dealing with.
In most instances, only "like" products can be welded together successfully.
There are two
simple processes to achieve this.
- Perform a short test weld. If
the welding rod stays firmly affixed to the base material
after it is thoroughly cooled, you have a successful material match.
- Perform a burn test. Take a
small piece of the plastic to be welded and expose it to
an open flame such as a match, lighter or small torch. Use extreme caution as the melted
plastic is very hot. Follow the chart below to determine which characteristics your material exhibits.
- PVDF-
Polyvinylidene Flouride. Produces an acrid odor and will burn to a black
ash. Flame will self-extinguish.
- TPUR-
Polyurethane. Produces a yellow flame, slight
black smoke and a
faint apple-like odor. Flame will not self-extinguish.
- ABS-
Acrylonitrile Butadiene Styrene. Produces a black smoke, soot
flakes and an acrid smell. Flame will not self-extinguish.
- PVC-
Polyvinyl Chloride. Produces a black medium smoke and an acrid smell. Flame
will self-extinguish.
- PE-
Polyethelene. Produces no smoke. Material drips like a candle and
smells of wax. Flame will not self-extinguish.
- PP-
Polypropylene. Produces no smoke. Material drips like a candle and smells of
burnt oil. Flame will not self-extinguish.
- PC-
Polycarbonate. Produces a yellowish sooty smoke and smells sweet.
The flame will self-extinguish.
- PS- Polystyrene. Produces a yellow flame, sooty smoke and smells of illuminating gas. Material drips. Flame will not self-extinguish.
