PET Processors L.L.C. (PPLLC) is a privately held company with
expertise in polymer processing. PPLLC is headquartered in Northeast
Ohio, the heart of the polymer belt, with access to a network of
academic, manufacturing, testing and equipment experts.
“We the Employees of PET Processors make the personal commitment to
understand, meet and when possible, exceed our customer’s
requirements through continuous improvement to our process . . .”
PPLLC operates a facility constructed in 1937 to manufacture rayon cord for tires, hoses
and belts by the Industrial Rayon Corporation. In the 1960's, the plant was expanded to
include polyester batch vacuum solid state polymerization (SSP) and polyester tire yarn.
Once the largest local employer, the plant was closed when acquired in 1981 by
Louisiana Chemical, which began liquidating the remaining manufacturing equipment.
Amongst the equipment were a number of rotary vacuum dryers (RVD) used to batch
solid state PET (Polyethylene Terephthalate) plastic pellets. These dryers were originally
installed in 1967 through 1972. Solid stating is a process involving heat and vacuum
lasting about a day which increases the molecular weight of the plastic. This makes
plastic stronger and gives it better properties for demanding applications like carbonated
beverage bottles, specialty automotive plastic and telecommunications connectors.
In 1984, a PET resin manufacturer approached Louisiana Chemical with a request to
process excess PET. Other requests followed and in 1986, PET Processors (PPLLC) was
created as a stand-alone business unit. In 1987, the remaining tire yarn extruders were
converted to pelletize PET post-consumer recycled materials. Other equipment and capacity
has been added over time to support the changing needs of our customers. Customers in the
1980's needed long runs of similar grades of PET in and out of rail cars.
In the early 1990's, the boom in clear beverage bottles began, with demand outstripping
supply. PPLLC played a big part in debottlenecking SSP supply problems. Throughput
was the objective, with annual output reaching one hundred million pounds per year.
Improvements were made to increase total capacity, with dedicated silos for product
By the middle 1990's, bottle PET supplies caught up to demand but specialty plastics and
engineered polymers continued to grow, with ever higher standards for testing, clean outs,
and process flexibility. PPLLC installed the first of three versatile twin screw extrusion
lines in response to the growing compounded product needs of our customers.
The late 1990's continued the trend towards engineered plastics and the highest quality
processing. On any given day, as many as 15 different products can be processed.
Capacity was increased again for high temperature products like LCP and HTN. The
prime quality recycled market became a focus and PPLLC became one of the top ten
producers servicing the recycled market in the USA. Our vacuum solid stating
process has become part of FDA NOL letters issued to customers.
Finally, in the 21st century, PPLLC aggressively expanded specialized services for
the polymer industry, including installation of a melt phase pilot plant supporting
resin development trial batches. The continued compounded product demand across all
polymers led to the installation of two additional twin screw extruders.
From the lab bench to market introduction, PPLLC offers an unsurpassed level of quality,
confidentiality, and flexibility supporting the most demanding product applications.
PPLLC is a
leader in thermoplastic recycling
PPLLC provides recycling solutions for post consumer and post industrial
resins, including PET. Single screw extrusion technology is used to melt,
process, and filter recycled flake into pellets. PPLLC's capabilities
include drying, extruding, and underwater pelletizing flake to provide a
pellet feedstock for further processing. PPLLC routinely increases the IV
of recycled polyesters and nylons for specialty applications.
