What kind of material is TPEE and what is the scope of application?

TPEE is a polyester elastomer, the natural color is milky white or light yellow, the hardness ranges from 30D to 84D, wear resistance, high tensile strength, oil resistance, aging resistance, wide range of temperatures, good processing performance, can have good adhesion to PC, PVC, ABS, PS, PBT and materials containing polyester groups, and PA, PP also have a certain adhesion strength.

It is commonly used in auto parts, antennas, silent gears, shock absorbing blocks, pipe fittings, etc.

TPEE is commonly known as Haicui material Because TPEE is the first DuPont to invest in the commercial field, the named trademark brand HYTREL, which is transliterated as Haicui.

TPEE (thermoplastic polyester elastomer) is a block copolymer containing a hard polyester segment and a polyether soft segment. Among them, the soft segment of polyether and the uncrystallized polyester form an amorphous phase, and the hard segment of polyester is partially crystallized to form a crystalline micro-region, which plays the role of a physical cross-linking point. TPEE has the elasticity of rubber and the strength of engineering plastics;The soft segment gives it elasticity and makes it rubber-like;The hard section gives it processability, making it like plastic;Compared with rubber, it has better processing properties and longer service life;Compared with engineering materials, it also has the characteristics of high strength, and has better flexibility and dynamic mechanical properties.

TPEE material is: sea green material. Haicui material is a kind of plastic raw material, also called TPEE, which is combined with engineering plastics.

and high-performance elastomers with rubber properties, which can create new applications for traditional and engineering plastics. TPEE is a high-performance grade of engineering rubber that can be processed into a wide range of products: calendered wafers extruded from injection molded fine parts.

G130D has similar flexibility to rubber.

elasticity as well as mechanical strength, but its heat resistance and weather resistance.

Better than rubber. G140D has similar flexibility, elasticity and mechanical strength to rubber, but it has better heat and weather resistance than rubber. G163D has similar flexibility, elasticity and mechanical strength to rubber, but its heat and weather resistance is better than rubber.

For most applications, TPEE can be used directly, and if there are special requirements for the Rona Banquet, corresponding additives can be added to meet the requirements. TPEE is mainly used in fields that require shock absorption, impact resistance, flex resistance, tightness and elasticity, oil and chemical resistance, and sufficient strength. Such as:

Polymer modification, auto parts, elastic soft wire, hydraulic hoses, shoe materials, transmission belts, rotary formed tires, gears, flexible couplings, silencing gears, elevator slides, anti-corrosion, wear-resistant, high-temperature and low-temperature materials in chemical equipment pipeline valves, etc.

1.It can be processed with general thermoplastic molding machines and does not require special processing equipment.

2.Productivity has been greatly improved. It can be vulcanized directly with a rubber injection molding machine, and the time is shortened from about 20min to less than 1min; Due to the short vulcanization time required, direct vulcanization with an extruder has been possible, and production efficiency has been greatly improved.

3.Easy to utilize, reduce costs. The waste materials generated in the production process (escaping burrs, extruding waste glue) and the final waste products can be directly returned for reuse; Used TPE products can be simply recycled and reused, reducing environmental pollution and expanding renewable resources.

TPE material Wang Bi is a material with high elasticity and high strength of rubber, and has the characteristics of injection molding. It is mainly used in high-end, high-transparency toys, suction cup materials, sports equipment and sealing rings. TPE materials can be processed by general thermoplastic trapped celery plastic molding machines, which do not require special processing equipment, and the waste materials generated in the production process can be directly returned for reuse; Moreover, waste TPE products can be easily recycled and reused to reduce environmental pollution.

In addition, most thermoplastic elastomers do not require vulcanization or have a short vulcanization time, which can effectively reduce the molding cycle. However, the heat resistance of TPE is not as good as that of rubber, and the physical properties decrease greatly as the temperature rises, so the scope of application is limited. And it is often higher than similar rubber.

In general, the advantages of TPE are still very prominent, and the disadvantages are constantly improving, as a new raw material for energy-saving and environmentally friendly rubber, the development prospect is still good.

Thermoplastic elastomers (TPEs), sometimes referred to as thermoplastic rubbers, are a class of copolymers or physical mixtures of polymers (usually plastic and rubber) that are composed of materials with thermoplastic and elastic properties. While most elastomers are thermosets, thermoplastics are relatively easy to use in manufacturing, such as through injection molding.

Thermoplastic elastomers show the typical advantages of rubber materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to medium elongation and return to close to the original shape, resulting in a longer life and better physical range than other materials. The main difference between thermoset elastomers and thermoplastic elastomers is the type of crosslinking bonds in their structure.

In fact, cross-linking is a key structural factor that confers high elasticity.
