Plastic extrusion has been in use since the early nineteenth century when it was popularized by some different innovators. To begin, Thomas Hancock developed a method for producing usable rubber from processed wastes in 1820. This he referred to as a rubber masticator. 

Edwin Chaffee, a colleague of the better renowned Charles Goodyear, then developed the first two-roll rubber mixing machine in 1836. While they were not intended for use with plastic, they were both adaptable and paved the way for further extrusion equipment.

Alexander Parkes invented the first synthetic plastic in 1862. His innovation garnered enough notice that he was allowed to exhibit it at that year's London World Fair. However, due to its high development cost and low quality, this plastic product was never widely utilized. 

Celluloid was the first practical man-made plastic. This was created in the United States by John Wesley Hyatt, who co-patented it with his brother Isaiah in 1870. 

Following the discovery of Celluloid, a plethora of additional plastic polymers, such as PVC and Bakelite, was developed. As the kinds and uses of plastic expanded, producers sought methods to create them more efficiently and precisely. There are various plastic packaging specialists all over the world.

The range of polymers for which plastic extrusion services are offered is very lengthy. It is composed of low-density polyethylene (LDPE), high-density polyethylene (HDPE), vinyl, polypropylene, polystyrene, butyrate, and PETG, among other materials.

LDPE:

Low-density polyethylene, or LDPE, is a tough and flexible material. Additionally, this plastic is extremely resistant to a wide range of chemicals, including esters, alcohols, bases, and acids.

HDPE:

As is the case with LDPE, HDPE, or high-density polyethylene, is a durable material. Additionally, it is resistant to corrosion and solvents, has a high strength-to-weight ratio, and high tensile strength.

Vinyl:

Vinyl, sometimes referred to as PVC (polyvinyl chloride), is a very common polymer. It is offered in two different types: flexible PVC and stiff PVC. It has the following properties: insulation, resistance to salt, acid, corrosion, base, fat, and alcohol. Unfortunately, vinyl is not particularly thermally stable unless it has a stabilizing ingredient. Siding, pipes, floor coverings, angles, and tubing are just a few of the most popular PVC extrusions.

Polypropylene:

Another very common polymer is polypropylene. It is resistant to heat, acid, base, and chemical solvents. Additionally, it has a low density.
