All the data cable materials you want to know are here.

The explosive growth of mobile digital devices represented by smart phones has brought great convenience to people’s lives and work. As the medium between the mobile phone and the charger, it is a data cable that does not seem to be very conspicuous, and its importance is often overlooked by people. And no matter how powerful the power is, it must be transmitted to the smart phone through the data cable. If a low-quality data cable is used, it will still cause the dilemma of prolonged charging time. But do you really understand this thread that you use every day? Do you know the material of the data cable in your hand? What kind of data cable is better? Then I will give you a popular science analysis.

As an ordinary consumer, the most intuitive feeling for the material of the data cable is that the cable is a bit hard or a bit soft and feels good. But in fact, this different feel represents the different outer material of the data cable, which is the outermost of the data cable. Although there are many types of data cables on the market, the outer covering materials used are nothing more than TPE, PVC, and braided wires.

ONE: PVC data cable

Polyvinyl chloride, abbreviated as PVC, is a polymer formed by the polymerization of vinyl chloride monomer (abbreviated as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat according to the free radical polymerization reaction mechanism.

PVC material is a commonly used material for most data cables. It has non-flammability, high strength, weather resistance and excellent geometric stability. The thread produced by this material feels hard.

Advantages of PVC data cable

1. Low cost, good insulation and weather resistance;
2. The price of PVC data cable is relatively cheap.

Disadvantages of PVC data cable

1. The texture is relatively hard and the resilience is poor, which is easy to cause breakage and peeling;
2. The surface is rough and dim;
3. There is a more obvious plastic smell, which will release harmful substances.

TWO. TPE data cable

TPE (Thermoplastic Elastomer) material is a material with high elasticity, high strength, high resilience of rubber, and the characteristics of injection molding. The basic structural feature of the thermoplastic elastomer polymer chain is that it simultaneously connects or grafts certain plastic segments (hard segments) and rubber segments (soft segments) with different chemical compositions. The force between the hard segments is sufficient to condense into micro-domains (such as vitrified micro-domains or crystalline micro-domains) to form physical “crosslinks” between molecules. The soft segment is a high-end segment with greater self-rotating ability.

To put it simply, TPE material is actually a soft rubber material that can be processed and formed by general thermoplastic molding machines. Its elasticity and toughness have been greatly improved compared with PVC materials. Can be recycled to reduce costs. At present, most of the original data cables of mobile phones are still made of TPE material. The thread produced with this material has a soft feel.

Advantages of TPE data cable

1. Excellent processing performance, excellent colorability, soft touch, weather resistance, fatigue resistance and temperature resistance;
2. It is safe and non-toxic, has no peculiar smell, and will not cause any irritation to human skin;
3. Can be recycled to reduce costs.

Disadvantages of TPE data cable

1. Intolerance to dirt;
2. No braided wire material is strong;
3. Improper use is prone to bursting.

Three, nylon braided data cable

Nylon-66, also known as nylon 66, polyamide-66, polyhexamethylene adipamide, a type of nylon, has the characteristics of flame retardancy, high strength, wear resistance, electrical insulation, etc., its plastic raw material It is a translucent, white or black crystalline polymer with plasticity. Nylon has strong strength and good abrasion resistance, ranking first among fibers. Its abrasion resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber.

Most of the braided data cables are made of nylon. It is well known that nylon is a kind of clothing material. Therefore, the flexural resistance and durability of the braided data cable is naturally higher than that of PVC and TPE materials. But the feel of the woven material is relatively less smooth than that of PVC and TPE.

Advantages of nylon braided data cable

1. Increase the aesthetics and external tensile strength of the data cable;
2. There is no snagging phenomenon, soft, bending and compliant, very good resilience, not easy to tangles or creases;
3. Excellent durability and not easy to deform.

Disadvantages of nylon braided data cable

1. High hygroscopicity;
2. Insufficient dimensional stability.

Four, polyester fiber braided data cable

Polyester fibre (polyester fibre) is a synthetic fibre obtained by spinning polyester formed by polycondensation of organic dibasic acid and diol, referred to as PET fibre (polyester). The specific gravity of polyester is 1.38; the melting point is 255～260℃, it starts to bond at 205℃, the safe ironing temperature is 135℃; the moisture absorption is very low, only 0.4%; the breaking strength of filament is 4.5～5.5g/d , Short fiber is 3.5～5.5 g/denier; the elongation at break of filament is 15～25%, short fiber is 25～40%; the strength of high-strength fiber can reach 7～8 g/den, and the elongation is 7.5～ 12.5%.

Advantages of polyester fiber braided data cable

1. Has excellent wrinkle resistance, elasticity and dimensional stability;
2. Have good electrical insulation properties;
3. Resistant to sunlight, abrasion, mildew and moth;
4. It has good resistance to chemical reagents, and can withstand weak acids and weak bases.

Disadvantages of polyester fiber braided data cable

1. Poor alkali resistance;
2. Poor dyeing performance.

Five, Kevlar data line

The original name of Kevlar in English is KEVLAR, which is also translated as Kevlar or Kevlar. It is the brand name of an aramid fiber material product developed by DuPont in the United States. The original name of the material is “polyparaphenylene terephthalamide”.

Advantages of Kevlar data cable

1. Low density, high strength, good toughness, high temperature resistance, easy processing and forming;
2. The strength reaches 3.6GPa, the elongation modulus is 131GPa, and the elongation at break is 2.8%;
3. Tough and wear-resistant, invulnerable.

Disadvantages of Kevlar data cable

The price is relatively high.

So, when it comes to this, some friends may ask: What kind of data cable is the best?
From the mainstream point of view of the market, the data cable using TPE/TPR thermoplastic elastomer material has excellent processing performance, is convenient to deploy a variety of beautiful colors, and is easy to process, can achieve matte or delicate effects, and make the hand feel smooth and not sticky. The material is safe and non-toxic, has no peculiar smell, and will not cause any irritation to human skin.

Not only that, the performance of the data cable made of TPE material is stable, the flame-retardant aspect reaches the V0 level, the phosphorus-free ozone resistance, and the reliable performance of safety and environmental protection have made it a mainstream in foreign countries. Therefore, it is not difficult to understand that the data lines produced by foreign players in the mobile phone field such as Apple and Samsung all use TPE/TPR elastomer materials.

In fact, each material has its own advantages. The key is what kind of feel and style you like. If you are a data cable player with a fever level, you may wish to try it out and find a material you like.
