Processes, types and kinds.


Used to describe a product of synthetic origin. Capable of being shaped at some stage of its manufacture. Made from coal, salt, natural gas, cotton, wood, water and from simple chemicals known as MONOMERS.


The basic ingredient of plastic

Injection Molding

Most popular method of processing plastics. It can produce moldings of high quality and with great accuracy. Used mostly for thermoplastics.

Blow Molding

This process is used in conjunction with extrusion. It is intended for use in manufacturing hollow plastic products. It produces hollow shapes.

Rotational Molding

Heat is used to melt and fuse a plastic resin inside a closed mold without using pressure. Rotation distributes the plastic into a uniform coating on the inside of the mold until the plastic part cools and sets.


First family of plastics. Their molecular structure is essentially linear and threadlike in form. They become soft when exposed to sufficient heat and hardens again when cooled, no matter how often the process is repeated.

Acrylonitrile Butadiene Styrene (ABS)

Tough but not brittle and is resistant to chemicals and to impact. It exhibits high gloss, low shrinkage and good dimensional stability.


"Polymethyl Methocrylate" these materials have the clarity of glass, good weatherbility, surface hardness and chemical resistance but not abrasion resistance. They are lightweight and color fast and do not yellow with age.


Primarily celluolose nitrate, cellulose acetate or cellulose butyrate. It was the first synthetic plastic material. In the 1860's it was the answer to Ivory shortage. Has good resistance to breakage.


A group of extremely inert plastics. They have a class of paraffinic polymers that have some or all the hydrogen replaced by flourine. As resins, dispersions, oils, greases and waxes. It has a high thermal ability, excellent resistance. Almost no moisture absorption. Polyvinyl Flouride (PVF) and polytetrathylene (TEFLON) are the most common flouroplastics.


Another term for Flourocarbons


They are tough, has a low frictional coefficient and resistant to chemical and oil damage, resists mechanical wear better than metals. They are elastic, easy to wash, can be pre colored or dyed in a wide range of colors. Its high softening temperature is exemplified by its replacement of brass for mixing valves in automatic washers.


A polymer offering an outstanding impact strength, dimensional stability under varying humidity or temperature, heat resistance, weather resistance and clarity. It uses injection molding.


Belongs to the family of Polyolefin Plastics. Exhibits good retention of mechanical properties at elevated temperature and high tensile stength; Used for plumbing supply pipes, hot metal adhesives and sealants.


Known for their strength and flexibility, They are tough materials, have excellent chemical resistance, offers a low coefficient of friction and are easy to process; Used for vapor barriers, molded seating, drawer glides and door tracks.


Composed of polymers and propylene. It is the lightest of all the commercial plastics. It is versatile and employed in many fabrication method. Semi-translucent or milky white in color excellent colorability and chemical resistance; Used for fiber, upholstery fabric, carpet backing, indoor/outdoor carpet fiber.
