How to identify the TPR sole

Each TPR is the most common and most common materials.

But in daily life, many people do not know this pair of shoes to wear on the foot Is it right? Belongs to what we say TPR material, then I will teach you a few strokes of the most simple method of identification.
To find TPR first and other different outsole material to distinguish. Such as PVC and PU or rubber etc..

1, there are a lot of people can’t tell PVC and sole actually these two kinds of materials easy to recognize TPR, PVC, TPR to be heavy in the hand than the sole material. The elasticity of the sole TPR material is better than PVC, is the most simple method, the sole firm hold, the natural fall if you can bounce back word is TPR, PVC. Material sole is TPR cheaper, but quality is not good, especially in the winter, very easy to break the bottom.

2, the identification of rubber bottom is also very simple, Rb bottom has a characteristic that is not an injection hole, and the nose to smell it, taste put longer words will long color to white material things.

The surface of the sole is light, TR 3. Compared with the general TPR sole to some hard. Multiple injection hole injection holes TR TPR is very special.
In fact, is not difficult to recognize these materials contact more, see at a glance soles will know what is the material of the.
Summary: in short, as long as you combine several appeal list, plus daily of careful observation and experience it is not difficult to identify.

Just one step to distinguish TPR, Silica gel and PVC

TPR, Silica gel and PVC,they resemble each other both in appearance and touch.It is so hard to distinguish for someone who is not familiar with these. Thermoplastic Rubber (TPR) Compounds that are available for a wide-range of applications. These compounds are formulated using Styrene-Butadiene-Styrene (SBS) .But TPR is not silica gel,they are different material.Now i tell you just one way to distinguish TPR, Silica gel and PVC.  

If you want to distinguish these three materials,you just need one Lighter.You just need to burn it by lighter.Then,pay attention to the color of flame and the smell of burning.

TPR: burning phenomena-The main body color of the flame is yellow, and the root of the flame is blue. Smoking smell:lighter or thicker smoke,fragrant smell.

Silica gel: burning phenomena - The main body color of the flame is bright white. The smoke and the smell of burning are light, and there is a clear white ash residue after combustion.

PVC : burning phenomena - The main body color of the flame is yellow,and the root of the flame is green.smoking smell:black and Dense smoke,bad smell (the smell of chlorine).

The concept of thermoplastic elastomer

1.The concept of thermoplastic elastomer

Thermoplastic elastomers (TPE), sometimes known as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers.

2.the types and Detailed introduction of TPE

TPE is the general term of thermoplastic elastomer. According to the different structure unit of raw materials, TPE Elastomer can divide into four types, including: Thermoplastic Elastomer(TPE), Thermoplastic Rubber(TPR), Thermoplastic Polyrethane(TPU), Thermoplastic Vulcanizate(TPV). The most common, most used for various applications in large quantites among these types of elastomers is TPE. so we will emphasis on the information about TPEs.

1.1 Styrene-polystyrene elastomer:TPE

TPE-s is one type of thermoplastic elastomers which base on SEBS and SBS.we usually called TPEor TPR(thermoplastic rubber).

1.2 The Basic properties of TPE-s

TPE has the basic propertied of Thermal plasticity processing of plastic and elasticity of rubber so we can adjust the hardness to have a comfortable touch feeling.
