Tips for welding thermoplastics

Welding is the process of uniting surfaces by softening them with heat. When welding thermoplastics, one of the key components is the material itself. For as long as plastic welding has been around many people still do not understand the basics which is critical to a proper weld. Learn more.

Polyesters, thermoplastic
Thermoplastic polyester molding compounds are crystalline, high-molecular-weight polymers that have an excellent balance of properties and processing characteristics. Because they crystallize rapidly and flow readily, mold cycles are short.

Thermoplastic polyesters have excellent resistance to a broad range of chemicals at room temperature including aliphatic hydrocarbons, gasoline, carbon tetrachloride, perchloroethylene, oils, fats, alcohols, glycols, esters, ethers and dilute acids and bases. They are attacked by strong acids and bases.

Polyesters, thermoset
Polyester resins of the thermosetting type are low-molecular-weight alkyd resins that are cross-linked with a monomer in a reaction initiated by a catalyst. At room temperature, the solutions-mixtures of resin and a liquid monomer (usually styrene) are stable for months. Any of a variety of peroxide catalysts can initiate cross-linking (curing) at room temperature or at higher temperatures.

Sustainability of Plastic: Did You Know…

More americans can recycle more kinds of plastic

A recent research study by Moore Recycling Associates (Sonoma, CA), sponsored by the American Chemistry Council (ACC), shows that more Americans have access to recycling than is generally believed and access continues to grow.

When Moore Recycling surveyed the 100 most populous U.S. cities in late 2008, only 29 of them had non-bottle rigid plastic recycling.

In the recent study it found that 59 of them do. Further, in 2008 each of the 100 biggest cities had PET and HDPE bottle recycling, but only 38 of them were recycling any rigid plastic beyond that.

Today 71 of the largest cities recycle other rigid plastics in addition to PET and HDPE bottles.

As Moore looked at the recycling programs of nearly 2500 cities during its recent study, it found 1128 cities and 213 unincorporated areas that collect all rigid plastic containers.
