Difference plastic cosmetic tube materials among TPE, PU and TPU

2021-10-12

The application range of plastic cosmetic tubes is very wide, such as food, cosmetics, skin care products and so on. Because of its low price, it is favored by major cosmetic tube manufacturers. Choosing the correct material of plastic cosmetic tube is a skill that cosmetics companies need to master. In the cosmetic tube factory, let’s take a brief look at the three types of plastic cosmetic tubes of TPE, TPU and PU, as a plastic cosmetic tube manufacturer, we are hoping to help customers in the choice of wholesale plastic cosmetic tubes.

　　What is TPE?

TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material used in the production of cosmetic tubes. It not only has the high elasticity, high strength, and high resilience of rubber, but also has the characteristics of injection molding. It is also environmentally friendly and non-toxic. It is safe and very suitable for plastic cosmetic tubes. It has a wide range of hardness, excellent colorability, soft touch, weather resistance, fatigue resistance and temperature resistance. TPE cosmetic tube can be a kind of PCR tube for cosmetic packaging.

　　 TPE material has superior processing performance from plastic cosmetic tube supplier, no need for vulcanization, and such plastic cosmetic tube packaging can be recycled to reduce costs. It can be molded by two-shot injection molding, covered and bonded with PP, PE, PC, PS, ABS and other base materials, or molded separately.

What is PU?

　　PU (polyurethane), polyurethane material, is the abbreviation of polyurethane, which is a kind of polymer material. PU is an emerging organic polymer material, known as the "fifth largest plastic". Because of its excellent performance, this plastic cosmetic packaging manufacturing material is widely used in cosmetic tubes and plastic bottles. It is the most common and the most widely used in the field of cosmetic packaging materials.tubes, cosmetic bottles.

　　What is TPU?

　　 The PU mentioned above is actually the raw material for the production of TPU. According to the processing technology from plastic cosmetic tube factory, PU can be subdivided into: CPU (cast polyurethane elastomer), TPU (thermoplastic polyurethane elastomer), MPU (mixed polyurethane elastomer).

　　 TPU is the thermoplastic polyurethane elastomer rubber, which is mainly divided into two types: polyester type and polyether type. Because TPU has a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity, it has been widely used, such as daily necessities, eye cream tube, lotion cosmetic tube, etc.

　　 It is worth mentioning that the field of cosmetic tube packaging materials for cosmetic tube manufacturers needs to meet environmental protection requirements. PVC materials may not meet the requirements, so halogen-free flame retardant TPU can be a perfect substitute for wholesale cosmetic tubes manufacturing.

What is the difference between TPE and TPU?
　　1. Incineration: TPE material has a good aroma when incineration, while TPU material is polyurethane, which has a slight impact on the smell of ammonia. At the same time, there is a slight blasting noise when TPU is incineration;
　　2. Strength and wear resistance: TPU has high strength and good wear resistance, which is significantly better than TPE material;

3. Softness: TPE material has a wide range of hardness (0A-90A), and the lowest hardness of TPU material is above 60A, so TPE material feels better, and TPU material feels harder.

PU material typical product-PU cosmetic tube
Application: PU plastic cosmetic tube as an anti-wear protective packaging tube, commonly used in face wash tube, sunscreen tube packaging.
Attributes: Anti-wear protection, optimized flow characteristics, high tensile strength, strong tear resistance; anti-microbial and hydrolysis, superior mineral oil resistance and chemical resistance, UV and ozone resistance, low temperature flexibility, bending radius It is small, not easy to kink, does not contain softener and halogen, does not leak gas and liquid, meets RoHS regulations, and can discharge static electricity through spiral wire grounding.
PU cosmetic tubes can be customized into food-grade cosmetic tubes. The cosmetic tube wall complies with: FDA 21 CFR 177.2600 and 178.2010, EC regulations 2002/72/EC, including the recently revised regulations 2007/19/EC independent authoritative testing agency certified to comply with EC 2002/72 /EC regulations.
