Located in Kulpsville, PA, Aline Components is a custom plastic injection molding and manufacturing company that process a variety of thermoplastic materials including PVC. To serve a broad base of customers that extend from Pennsylvania, New Jersey, New York, and Delaware to locations throughout the entire United States we ensure that every thermoplastic material is tailored to meet custom plastic part or component applications. We work directly with resin suppliers to offer PVC in transparent or opaque formats, as well as grades that are durable, weatherproof, flame resistant, and more.
One of the most versatile of all the engineering resins, PVC can be used in either rigid or soft (plasticised) form, which doubles its market value. Although PVC has been scrutinized as a dangerous material by some and has been subjected to more research than other thermoplastics, many now acknowledge it as an exceptionally safe material. In fact PVC, when used as the main material in blood bags and other medical devices, has been responsible for saving countless lives. At Aline Components, we help you determine if PVC is an ideal solution for your end product or subsystem.
An amorphous, polar thermoplastic, PVC exhibits many high performance properties, which can be altered by initial formulation, plasticizer content, and plastic injection molding and manufacturing to meet individual specifications and regulations. Depending on the method of polymerization used by resin suppliers, PVC is available in rigid PVC and soft or plasticised PVC.
Rigid PVC is a hard, stiff thermoplastic material with good abrasion resistance. Once its high tensile strength is maximized under a tensile load, rigid PVC flows in a plastic manner as tensile strength is eliminated, until plastic fracture takes place. When compared to impact strength, rigid PVC’s notched impact strength is low. Another form of PVC is plasticised PVC. Strong dampening and slow, resilient recovery characterize the elastic behavior of plasticised PVC. Plasticised PVC is suitable for applications that require shock and vibration absorption.
Overall PVC exhibits good mechanical and thermal properties. Rigid PVC is best used in a temperature range between -5°C and 60°C. However, with the integration of various copolymers, rigid PVC can be used up to 80°C and impact resistant grades can be used at temperatures as low as -25°C. Plasticised PVC can be used up to 40°C or, with some types, 60°C. Depending on the type and content of the plasticizer used, soft PVC can be used in temperatures as low as –10 to -50°C.
The versatility of PVC is that it allows for the production of materials ranging from elastomers to stiff engineering thermoplastics. Whether your custom plastic part or component requires rigid PVC or plasticised PVC, there are many advantages to using this type of plastic. While rigid PVC tend to have slightly better properties than plasticised PVC, both are resistant to weathering, light, and aging. At room temperatures, rigid PVC maintains good dimensional stability. Due to the presence of plasticizers, soft PVC has a slightly worse chemical resistance, however, both resist a variety of acids, alkalis, oils, alcohols, aliphatic hydrocarbons, detergent solutions, and many corrosive inorganic chemicals.
