LCP (Liquid Crystal Polymer): 
The Ideal Option for Challenging Performance LCP is a top-performing plastic used in engineering with outstanding features, such as excellent heat resistance, strength, stiffness, and low water absorption. Its heat resistance goes up to 280°C, and it melts at 330°C, making it the first choice in extreme situations. LCP is extensively utilized in micro-connectors and optical fiber connectors. Micro-connectors are often used in devices like mobile phones, laptops, and cameras, while optical fibre connectors are used in the medical, military, and communications fields to transmit high-speed optical signals. LCP has low-temperature resistance that can go down to -40°C, and its dimensions and performance won't be affected by water absorption.

PBT: An Option for Moderate Performance
PBT is a type of engineering plastic that can withstand heat, age, and chemicals, and is resistant to water. It can resist up to 55°C of heat and has a melting point of 225°C, which makes it appropriate for general connectors. Its typical applications are in the fields of automotive electronic systems and power transmission, particularly in automotive connectors and power connectors. Please note that PBT may be impacted by water absorption at extreme temperatures, leading to changes in performance and dimensions.The low-temperature resistance rating of PBT depends on its specific composition but typically can withstand temperatures as low as -40°C.

PBT (Polybutylene Terephthalate): A Medium-Performance Option
PBT is an engineering plastic with good heat resistance, aging resistance, chemical resistance, and low water absorption. Its heat resistance grade is 55°C, and its melting point is 225°C, making it suitable for general-purpose connectors. Automotive connectors and power connectors are common application fields, used in automotive electronic systems and power transmission. However, it should be noted that PBT may be affected by water absorption at extreme temperatures, which can lead to changes in dimensions and performance. The low-temperature resistance grade of PBT depends on the specific formula, but it can generally reach -40°C.

ABS (Acrylonitrile-Butadiene-Styrene Copolymer): Ideal for Low-Temperature, Low-Pressure Uses.
ABS is a multi-use plastic that's tough, durable, and easy to shape. However, it's not well-suited to high-temperature environments because it has a low heat resistance level. Its glass transition temperature (Tg) is only 105°C and it doesn't have a definite melting point. This means that ABS is most suitable for applications that don't involve high temperatures, pressures, or frequencies.Audio and telephone connectors are often made from ABS material and used in various jacks, including those for headphones, microphones, and speakers, as well as RJ11 and RJ45. It's important to note that the low-temperature durability of ABS varies depending on the formula, but generally, it can withstand temperatures as low as -20°C for applications requiring low-temperature resistance.
