PBT Thermoplastic Material at Aline Components Plastic Injection Molding and Manufacturing Company

A recognized plastic injection molding and manufacturing company in Kulpsville, PA, Aline Components, offers PBT thermoplastic materials for a wide range of custom plastic part and component applications. Local customers in Pennsylvania, New Jersey, New York, Delaware, and Maryland as well as those based nationally and abroad are using PBT as insulators in electrical industries, exterior parts in automotive industries, keyboard buttons in computing industries, and more.

At Aline Components, we can help you determine if PBT plastic is suitable for your application requirements. We invest in the highest quality GE plastics, specifically Valox®, to deliver the injection molded plastic part your product or system needs to perform to the highest possible level. As a self-lubricating thermoplastic material, PBT plastic exhibits excellent mechanical and electrical properties combined with good chemical and impact resistance.

What is PBT Thermoplastic Material?

A type of polyester, polybutylene terephthalate (PBT) is a thermoplastic crystalline polymer. Polybutylene terephthalate is the product of a reaction between butanediol and dimethyl terephthalate or terephthalic acid. With polybutylene terephthalate as a base, different grades emerge (such as Valox®) through additives like fiberglass, minerals like mica or wollastonite, stainless steel fibers or carbon fibers, non-orienting fillers like glass beads, UV stabilizers, impact modifiers, and more.

PBT Plastic Properties

Often compared to polyamide nylon, PBT plastic exhibits extremely low water absorption. As a result of low water absorption superior dimensional stability is achieved. The tensile strength of PBT is between 6,000 and 13,000 psi, while the flexural modulus is between 300,000 and 1,200,000 psi. PBT plastic performs best at service temperatures ranging from -40°F to 250°F for long-term use and 420°F for shorter durations.

Advantages of PBT Plastic Include:
  • High and low temperature performance
  • Excellent impact and dielectric strength
  • Heat and flame resistance
  • Dimensional accuracy and stability
  • Chemical resistance
Benefits of PBT Plastic

Based on polybutylene terephthalate PBT, Valox® is a thermoplastic polyester resin which combines high mechanical, thermal, and electrical properties with good chemical resistance. Valox® maintains its properties when in contact with chemicals such as aliphatic hydrocarbons, petrol, oils and greases, detergents, dilute acids and bases, and most aqueous salt solutions kept at ambient temperatures.

Through the use of impact modifiers, PBT plastic can achieve high levels of impact strength. Flame retardant grades are available upon request. The variety of PBT-based product performance available in the marketplace is a compliment to the versatility and flexibility of this thermoplastic material. Today PBT is considered one of the most commercially significant engineering resins in the family of polyesters.

Moldability, dimensional stability, environmental and temperature resistance, electrical insulation properties, range of color capabilities, and high quality surface finishes all contribute to the dynamic success of Aline’s PBT custom plastic parts and components. Aline Components prides itself on being an extremely capable plastic injection molding and manufacturing company and employs dedicated designers and mold makers that work with customers to make sure they obtain the right thermoplastic material for their distinct application.
