2. About PBT plastic
2.1. Definition of PBT plastic
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer resin used as an insulator in the electrical and electronic industries. It is a semi-finished plastic crystalline polymer.
2.2. Properties of PBT plastic
PBT is solvent resistant, stretches little during forming, is heat resistant up to 150°C (or 200°C with fiberglass reinforcement) and can be reinforced with flame retardants to make it non-combustible.
2.3. Applications of PBT plastic
- Polybutylene terephthalate is widely used in electrical engineering, construction, the manufacture of car sockets and household appliances such as showers or irons.
- It is also made into toothbrushes, false eyelashes, and is used in the keycaps of some high-end computer keyboards because the texture is resistant to abrasion and discoloration from UV radiation.
- Widely used in swimming pool equipment, due to its strong resistance to water and chlorine.
- PBT has high fire resistance and hardness, so it is widely used in the production of plastic parts for cars, motorcycles, batteries, radiator fans, and household electrical appliances.
Applications of PBT plastic
2.4. PBT compound
PBT plastic compound is an engineering plastic based on PBT primary plastic, mixed with many different additives and reinforcements such as glass fiber, color, flame retardant additives according to different formulas to meet the properties. specific characteristics of each plastic product.
European Plastic Company provides the main PBT compound product lines which are glass fiber PBT compound (PBT–GF), V0 flame retardant PBT compound (PBT–FR). The material is applied in electrical engineering, construction, industry, socket manufacturing, household appliances.

PBT GF-FR compound
PBT group GF-FR is a compound product made from PBT resin with glass fiber and flame retardant additives. Depending on customer needs, EuP provides compound codes with glass fiber ratio and fire resistance level according to UL94 standards: 5VA, 5VB, V0, V1, V2 as appropriate. With fire resistance and high hardness, GF-FR group PBT is widely used in the manufacture of parts for cars, motorcycles, battery turbines, radiator fans, and household electrical appliances.
