The difference between pure TPE and two color TPE is:

It can be processed with general thermoplastic molding machines and does not require special processing equipment. 2.The production efficiency 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 used, and the 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. 4.Energy conservation.

Most thermoplastic elastomers do not require vulcanization or have a short vulcanization time, which can effectively save energy. Take the energy consumption of high-pressure hose production as an example: 188MJ kg for rubber and 144MJ kg for TPE

Judging by what you have expressed.

Pure TPE should refer to TPE molded separately, that is, the whole product is made of TPE, without matching with other materials, and without lagging (two-color, or overmolding).

Two-color TPE, it should be different hardness TPE mutual wrapping, or TPE wrapping other hardness, such as ABS, PP, PC, NYLON, etc.!

The difference between the two of them is that one is that the whole product is made of TPE, and the other is molded with two materials! I don't know if you can get it.

To ask this question, it should be that you know very little about TPE, by the way, I will introduce to you what TPE material is.

TPE material is a kind of rubber-like material, also commonly known as artificial rubber, which can be molded separately or bonded with other materials, commonly known as lagging in our industry, overmolding, two-color, etc. The part of the soft color of the toothbrush handle that we commonly see in our lives is TPE!

Hope mine can help you!

If the hardness is the same, there is no difference in function! It's just that the two-color ones are better-looking, and the color matching is rich, which improves the appearance!

TPE: Thermoplastic Elastomer TPR: Thermoplastic Rubber refers to a class of materials that can be processed by the thermoplastic process of processing plastics and have the elastic use function of rubber.

Including TPE-S, TPE-V, TPE-U, TPE-A, TPE-E, etc.

You can take a look at what the following ** says about TPE.

TPE and TPU are both thermoplastic elastomer materials, and their main differences are their chemical structure, physical properties, and application fields.

Chemical structure: TPE material is a composite material composed of thermoplastic elastomer and plastic, while TPU material is a composite material composed of polyurethane and elastomer.

Physical properties: TPE material has good flexibility, wear resistance and cold resistance, while TPU material has higher strength, hardness and wear resistance. In addition, the elastic modulus of TPE material is lower, whereas the elastic modulus of TPU material is higher.

Applications: TPE materials are usually used to make hoses, seals, automotive parts and other products, while TPU materials are usually used to make shoe soles, sports equipment, cable sheaths and other products.

No. TPE is a thermoplastic elastomer, the soft leather wrapped on the toothbrush is made of TPE, and PET is polyester, the raw material for many mineral water bottles.

No, one is a thermoplastic elastomer, PET is polyethylene terephthalate, polyester.

TPE is the fastest growing elastomer material in the past 20 years, the material can be bonded together with PP, ABS, PC, PS, PA and other engineering plastics, without any additives and glue, only need secondary molding! The material is non-toxic and environmentally friendly, widely used in daily necessities, automotive electronics, sporting goods, baby products, etc., the color part of the toothbrush handle commonly used in our daily life, soft and soft, that is, TPE material. PVC Chinese called polyvinyl chloride, material characteristics, high strength, good wear resistance, has good flame retardant properties, the biggest feature is that PVC has memory function.

When it is melted and shaped into a certain shape, no matter how the outside world squeezes it at room temperature, when the force disappears, it will return to its original state. The most common products in life - all kinds of suction cups are enough to illustrate this feature of PVC.

PVC gloves are made of PVC paste resin, plasticizer, stabilizer, viscosity reducer, PU and softened water as the main raw materials, and are made through a special process.

TPE gloves are made of SEBS-based material, elastomer and polyethylene resin.

2. Differences in characteristics.

PVC gloves are allergen-free; Low dust generation and low ion content; It has strong chemical resistance and resistance to a certain pH; It has strong tensile strength, puncture resistance, and is not easy to break; It has good flexibility and touch, and is convenient and comfortable to wear; It has anti-static properties.

TPE is a polyole hydroelastomer.

PVC is polyvinyl chloride. All belong to the category of plastic and polymer materials.

TPE vs. PVC performance comparison:

Ingredient - TPE: Hydrocarbon; PVC: chlorine-containing hydrocarbons.

Characteristics-TPE: the use of injection molding machine, odorless process, no corrosion of equipment, reduce equipment maintenance costs, harmless to the environment and human body; PVC: The use of injection molding machine, plasticizer containing DOP, foul odor during processing, easy to pollute the environment, strict waste disposal methods.

Use low temperature limit-TPE: up to -50, with excellent weather resistance and low temperature performance; pvc：-10℃。

Specific gravity-tpe:; pvc：。

Hardness - TPE: 0A 98A; pvc：40a～98a。

Others-TPE: non-toxic, low pollution, good environmental protection effect; PVC: Restricted in European countries.

Generally, the injection TPE should make the fluidity better according to the need, and the extruded TPE should generally make the melt index slightly lower, and a certain melt strength is required, which is to have a good shaping effect! Of course, to make wires, the finger melting does not have to be small, and the outlet expansion needs to be small, so that it is easier to extrude quickly.

TPE is the abbreviation of Thermoplastic Elastomer, which means thermoplastic elastomer. TPE is generally considered to be synthetically modified by SEBS (styrene block copolymer) in the elastomer industry. TPE secondary injection molding generally refers to the injection of rigid plastic PP, PS, ABS, PC, PA, etc., and then through the injection molding process on the surface of the rigid plastic material to coat a relatively thin layer of TPE soft rubber.

In order to increase the comfortable touch, anti-slip performance and anti-impact performance of the product.

The main reason is that the fluidity and melt strength are different, which is suitable for the corresponding processing technology.

Injection molding requires better fluidity than extrusion.
