1. Introduction:
CCP Thermoplastic Polyester Elastomer (TPEE) is an engineering plastic material developed by Changchun Company in response to industrial upgrades, after years of significant investment in human and material resources for research and development, produced with proprietary technology to supply the industry with the best quality TPEE at lower costs.
What is TPEE material?
TPEE (Thermoplastic Polyester Elastomer) is the Chinese name for thermoplastic polyester elastomer.It is formed by the copolymerization of 1,4-Butylene glycol and Polytetra-methylene glycol with Dimethyl terephthalate (DMT) or Terephthalic acid (PTA), and can be made into thermoplastic polyester elastomer composite materials through mixing processes.TPEE has many excellent characteristics and is widely used in the electrical, telecommunications, and automotive industries.
2. Characteristics of TPEE:

1. TPEE has the elasticity of rubber and the strength of engineering plastics; the soft segments give it elasticity, making it like rubber; the hard segments provide it with processing performance, making it like plastic; compared to rubber, it has better processing performance and a longer service life; compared to engineering materials, it also has high strength characteristics, with better flexibility and dynamic mechanical properties.

2. Mechanical properties: By adjusting the ratio of soft and hard segments, the hardness of TPEE can range from Shore 30-82D, with its elasticity and strength lying between rubber and plastic. Compared to other thermoplastic elastomers, TPEE has a higher modulus under low strain conditions. When modulus is an important design condition, using TPEE can reduce the cross-sectional area of products and decrease material usage. TPEE has extremely high tensile strength. Compared to polyurethane (TPU), TPEE has a much higher compressive modulus and tensile modulus; using the same hardness TPEE and TPU to make the same part, the former can bear a greater load. Above room temperature, TPEE has a high bending modulus, while at low temperatures, it does not become overly rigid like TPU, making it suitable for making cantilever beams or torque-type components, especially suitable for high-temperature components. TPEE has good low-temperature flexibility.

Its low-temperature notch impact strength is superior to other TPEs, and its wear resistance is comparable to TPU. Under low strain conditions, TPEE exhibits excellent fatigue resistance with minimal hysteresis loss, which, combined with its high elasticity, makes this material ideal for use under cyclic loading conditions, suitable for gears, rubber rollers, flexible couplings, and belts.
3. Thermal properties: TPEE has excellent heat resistance; the higher the hardness, the better the heat resistance. TPEE shows virtually no weight loss after being continuously heated at 110-140°C for 10 hours, and after heating at 160°C and 180°C for 10 hours, the weight loss is only 0.05% and 0.1%, respectively, making the operating temperature of TPEE very high, with even higher short-term usage temperatures, able to withstand the baking and painting temperatures on automotive production lines (150-160°C), and it exhibits minimal mechanical property loss at high and low temperatures. When used above 120°C, its tensile strength far exceeds that of TPU. Additionally, TPEE has outstanding low-temperature performance, with a brittle point below -70°C, and the lower the hardness, the better the cold resistance; most TPEE can be used long-term at -40°C. Due to the balanced performance exhibited by TPEE at high and low temperatures, its working temperature range is very wide, usable from -70 to 200°C.

4. Chemical resistance: TPEE has excellent oil resistance and can withstand most polar liquid chemical media (such as acids, bases, and amine glycol compounds) at room temperature, but it is ineffective against halogenated hydrocarbons (except for chlorofluorocarbons) and phenolic compounds; its chemical resistance improves with increased hardness. TPEE has good anti-swelling and anti-permeation properties against most organic solvents, fuels, and gases, with fuel permeability only 1/3 to 1/300 that of oil-resistant rubbers like neoprene, chlorosulfonated polyethylene, and nitrile rubber; however, TPEE has poor resistance to hot water, and adding polyimide stabilizers can significantly improve its hydrolysis resistance.

5. Weather resistance and aging resistance: TPEE exhibits excellent chemical stability under various conditions, such as water mist, ozone, and outdoor atmospheric aging. Like most elastomers, it degrades under UV light, so for outdoor applications or products exposed to sunlight, UV protective additives should be added to the formulation, including carbon black and various pigments or other shielding materials; additionally, TPEE has varying degrees of hydrolysis susceptibility.
