What Is Polypropylene? 

Polypropylene is a versatile thermoplastic polymer resin that is used throughout industry as a structural and a fiber-type plastic. It is a strong, durable material with a high melting point, high tensile and compressive strength, excellent dielectric properties, and is resistant to most acids and solvents. It is weatherproof and has low moisture absorption. Polypropylene is easy to color or pigment. In addition, it is lightweight and flexible. Melt processing such as extruding can result in increased bonding and strength in the material. 

Polypropylene is used for applications in the construction, electrical, medical device, automotive, furniture, and chemical and petrochemical processing industries. Some of the custom polypropylene parts we manufacture at Preferred Plastics are:
