Welding technologies used for thermoplastic sheet and pipe
Training class for thermoplastic welder certification.

Without the ability to weld thermoplastics such as PP, PE, PVC, CPVC, PVDF and higher fluorinated polymers these materials would not have the position in the marketplace they have today. Learn more.

Advancement of thermoplastics in commercial aerospace

The Airbus A319 was the first commercial aircraft to dare to have a non-metallic leading edge on its wings — it used a PPS/ woven carbon fiber composite. However, since its first flight, the advancement in the use of thermoplastics within the airframe, engine and auxiliary systems of commercial aircraft in Europe and the United States has been slow, but steady.

In the 1970s, commercial airline objectives were weight reduction, increased safety factors, lower manufacturing costs and reduced maintenance schedules. To fulfill these goals, aerospace engineers looked to thermoplastic material manufacturers and component suppliers.

Technical advisory

• Plastics are changed into useful shapes by using many different processes. The processes that are used to mold or shape thermoplastics basically soften the plastic material so it can be injected into a mold, extruded through a die or formed in or over a mold.

• Some of the more common processes are injection molding, extrusion, blow molding, rotational molding, calendering, thermoforming (which includes vacuum forming) and casting.

• Thermosets must use a process that allows the material to flow to the desired shape and then become polymerized or cross-linked and rigid.


Sustainability of plastic: Did you know…

• Thermoplastic and thermoset materials both fall under the broad category of Polymers. The biggest difference between a thermoplastic and thermoset is that a thermoplastic can be recycled.

• Thermoplastics can go through melting/freezing cycles repeatedly and the fact that they can be reshaped upon reheating gives them their name. This quality makes thermoplastics recyclable.

• The processes required for recycling vary with the thermoplastic. The most commonly recycled thermoplastics are PE, PP, PS and PVC.
