Looking for a thermoplastic material that is lightweight, stiff, and exhibits excellent temperature performance and dimensional stability? PET plastic is your custom plastic part or component solution. At Aline Components plastic injection molding and manufacturing company, we invest in the finest resins such as Rynite® from preferred developers like DuPont™ to provide customers with high-grade PET plastic products suitable for diver applications.
A preferred mold maker located in Kulpsville, PA, Aline Components serves customers based internationally, nationally, and regionally in Pennsylvania, New Jersey, New York, Delaware, and Maryland. We work directly with resin suppliers to make sure that we custom mold and manufacture your part using the best possible thermoplastic material to meet exact specifications. Once we establish your end product or system requirements, our designers can help you ascertain whether PET plastic is the right choice.
Polyethylene terephthalate, or PET, is a thermoplastic resin, which derives from the polyester family and is commonly used in food and beverage applications. Depending on processing, PET can be semi-rigid or rigid, or amorphous (transparent) or semi-crystalline (opaque and white). PET can be synthesized through a transesterification reaction between ethylene glycol and dimethyl terephthalate.
In some cases, PET plastic can be modified for more desirable properties. For example, when glass particles or fibers are integrated, PET becomes significantly stiffer and more durable under various conditions. This glass-filled thermoplastic, semi-crystalline formulation is developed by DuPont™ and sold under the name Rynite®.
Although PET in its natural state is colorless and transparent, it can be reinforced to meet customer’s color requirements. In addition, certain reinforcements make PET plastic a good gas and fair moisture barrier, as well as a good barrier to alcohol and solvents. To alleviate potential degradation, comonomers such as cyclohexane dimethanol (CHDM) or isophthalic acid are used to lower PET’s melting temperature. These are just a few examples of how reinforcements can alter the physical properties of PET.
The strength and impact resistance of PET plastic make it an ideal material for a variety of custom part or component applications. When compared to PBT, PET has a 20°C heat deflection advantage. When compared to most other materials, PET is one of the few thermoplastics whose polymer chains can be recovered for use as recycled goods.
As a prime custom plastic injection molding and manufacturing company, Aline Components utilizes a one-step plastic injection molding process to deliver parts or components to the highest standard at a quick turnaround. The remarkable flow characteristics of Rynite® PET allow Aline Components to fill complex, thin-walled molds with less injection pressure than other thermoplastic resins. Extensive experience as mold makers and plastic part manufacturers combined with long-established relationships with recognized resin suppliers contribute to the cost-effective value of Aline Components.
