• WHICH ARE THE THERMOPLASTIC ELASTOMERS

The thermoplastic elastomers (TPE), sometimes referred to as rubbers, thermoplastics, are a class of copolymers or a physical mixture of polymers (usually a plastic and a rubber) which behave with the same properties of thermoplastics and elastomers.

While most elastomers are thermosets, thermoplastics are in contrast relatively easy to mold by the usual methods of transformation, such as, for example, by injection molding, commonly used for the design of sex dolls.

The thermoplastic elastomers show the advantages typical of both materials. The main difference between elastomers, thermoset and thermoplastic elastomers is the type of cross-linking in their structures. In fact, crosslinking is a critical structural which contributes to impart high elastic properties.

It was not until the 1950s, when thermoplastic polymers of polyurethane came to be available, which turned the TPE into a commercial reality. During the 1960s the block copolymers of styrene were available, and in the 1970s a wide range of thermoplastic elastomers came on the scene. The global use of TPE (680.000 tons / year in 1990) grew up in a order of 9% per year.

  • DIFFERENCES WITH THE SILICONE STANDARD

More that be better or worse, we will focus on pointing out differences, which we will see the properties that some would consider better and others worse:

The silicone also has a very realist look. which makes it an excellent guarantor of a visual experience that is flawless therefore you will find sex dolls manufactured in this material.

It is a material of a high reliability since it is used with success for a long time.
Unlike the TPE material is Non-porous and more resistant to heat

The TPE is more soft and elastic than the silicone standard that has properties more rigid and hard.

The TPE is more porous so that certain materials may be impregnated , which means maintenance is more regular than that of the silicon standard in order to maintain their appearance. In Sex Doll Spain we recommend water and soap for proper cleaning of your sex dolls.

  • SUSTAINABLE MATERIAL

Materials TPE have the potential to be recyclable since they can be molded and reused like plastics, but have the elastic properties typical of rubbers which are not recyclable, due to its characteristics, thermosetting

The cross-linking makes it possible. But the polymers are crosslinked and cannot be easily recycled. So, in the interest of preserving the earth being a giant trash can, we have suggested a new proposal, the thermoplastic elastomer.

The idea behind thermoplastic elastomers is the notion of a cross-linking reversible.
The polymers cross-linked normally can't be recycled because it does not melt. And don't melt because the cross-linking binds the chains, preventing that the material is able to flow.

Here is where the cross-linking reversible. The reticules are normal covalent bonds, bonding chemically to the polymeric chains in a single molecule. The cross-linking reversible, employs secondary interactions non-covalent bonds to link together the chains. These interactions include the links by bridge hydrogen and ionic bonds.

The charm of using non-covalent interactions to form reticules is that when the material is heated, the lattices are broken. This allows the material to be processed, and most important, recycling. When it cools down, the crosshairs return to form.

  • APPLICATIONS

In addition to design sex dolls Sex Doll Spain. The TPE is used when the elastomer conventional may not provide the range of physical properties needed in the product. These materials find large application in the automotive sector and the sector of appliances for the home.

In addition, the TPE copolyester used in tracks of snowmobiles, in which the rigidity and the abrasion resistance is a luxury. They are also widely used for catheters, in which the block copolymers of nylon offer a softness ideal for patients. Mixtures of thermoplastic silicon and olefin are used for the extrusion of profiles of weatherstripping for the glass cars.

Block copolymers of styrene are used in the soles of shoes due to their ease of processing, and is widely used as an adhesive. The TPE is commonly used to make suspension bushings for automotive components, due to their higher resistance to deformation when compared with rubber bushings regular. It is used by some manufacturers of glasses menstrual. The TPE is also finding more and more uses as a jacket of electrical wire / insulation inside.

The TPE is also used in some earphone cords. Another widespread use is in handles of toothbrushes and razors disposable obtained through injection or bi-component. It is also used in tool handles such as hammers and drivers, for a better grip.
