PBT
Plastic Dana
đŁđđ§ đŁđšđŽđđđśđ° đđżđŽđťđđšđ˛đ & đđżđđđľPolybutylene Terephthalate (PBT) Plastic Dana is a high-performance engineering thermoplastic known for its excellent mechanical and thermal properties.
Here’s an overview:
Composition: PBT is a semi-crystalline polymer made from the polymerization of butanediol (BDO) and terephthalic acid (TPA) or dimethyl terephthalate (DMT). It is typically supplied as small granules or pellets, known as "Dana."
Properties:
High Strength and Stiffness: PBT has a high tensile strength and rigidity, making it suitable for applications requiring mechanical robustness.
Low Moisture Absorption: It absorbs very little moisture, which helps maintain its dimensional stability and mechanical properties even in humid environments.
Thermal Stability: PBT can withstand high temperatures, typically up to 150°C (or higher with glass fiber reinforcement).
Chemical Resistance: It is resistant to various chemicals, including oils, greases, and solvents.
Electrical Insulation: PBT has excellent insulating properties, making it ideal for electrical and electronic applications.
Flame Retardancy: PBT can be treated with flame retardants to enhance its fire resistance.
Applications: PBT Dana is widely used in automotive parts (e.g., connectors, switches, and sensors), consumer electronics, medical devices, and industrial machinery due to its durability and reliability.
