PVC, silica gel and TPE-which is the best choice for sex toys ?

As sex toys are direct contact with human sexual organs, for the protection of the body, it is more important to Pursuit real sexual experience, These requir the raw material of sex toys must be very soft and healthy for body.the most common soft raw material including: PVC, silica gel and TPE (Thermoplastic Elastomer). different uses of sex toys,different hardness of the raw material. some dildos and vibrators for woman usually using the soft material of 5-20 shore A and the processing is injection molding.But some Male Masturbators usually using the ultra soft TPE material of below 0 shore A(such as:000 or even 00000) and the processing are injection molding and pouring. The pouring is usually used for the large size male sex toys.Let's talk about the Advantages and disadvantages of PVC, silica gel and TPE for sex toys.

Look at PVC first. PVC is a polyvinyl chloride resin,we can let the hardness of PVC drop to very sofe by adding a large number of plasticizer (usually phthalate plasticizer DOP) even 0 shore A.The advantage of PVC: low price, Bright color, can be rapid injection molding processing.The disavantage: bad smell, the most important is that plasticizer is poisonous. Although PVC is not directly contact with the human oral airway, people always worry about the safety.Some high-end sex toys always using more More environmentally friendly materials but not PVC. What is more,for some sex toys of blow 0 shore A, PVC is difficult to reach the ultra soft touching.

Look at the silica gel. Chemical element of silica gel is a silicon and oxygen, does not contain benzene toxic molecular structure, crosslinking agent of silica gel usually uses the environmental protection of varieties. Therefore, silica gel is a very environmentally friendly soft material. For a long time, silica gel is the most common soft material used in the dult products. The hardness of silica gel for adult products can be adjusted in 0~20 shore A. The disadvantage of silica gel:high price, long molding cycle, and the raw material can not be recycled.

Finally look at TPE/TPR. soft material TPE for sex toys is based on SEBS , we usually use the environmentally-friendly operating oil as a modifier to adjust the viscosity and hardness of SEBS. The formulation system is relatively simple because it is a super soft material for use in sex toys. TPE is a environmentally-friendly soft material and its constituent components-SEBS and operating oil do not contain plasticizers which can pass the detection of o-phenylenediamine 16p, nonyl phenol (NP), polycyclic aromatic hydrocarbons PAHs. The hardness of TPE can be adjusted to be softer than silica gel so TPE is the ideal raw material for sex toys. some TPE sex toys may be a little sticky feeling, there will be a certain smell because of the oil, we can add some Smoothing Agent and flavor to improve the properties. The advanatge of TPE: moderate price, Recycling materials, safety.

In general,if you really care about the price and have few requirements for the raw material,PVC is a choice for you.If you care about the experience and the environmental protection,silica gel and TPE are better than PVC. However,the price of silica gel is higher than TPE.As far as I'm concerned,i think TPE is the best choice for sex toys.

TPE/TPR vs PVC in toy industry

The toy industry has been the important export industry in China. Soft plastic toys is always an active element in toy industry, such as: cartoon dolls, doll eraser, monster high fashion doll toys and the simulation toys and so on. They has been praised by foreign and domestic children.

But all the toy entrepreneurs feel that Export environmental safety inspection of toy industry is becoming more and more strict, Export inspection strict inevitably lead to the problems of production management and the rising cost of raw materials, so, toy companies only constantly digging and find the market demand, develop high value-added products so they can be in a better position to in the fierce competition of market.

At present most domestic enterprises usually use PVC soft rubber to produce toys. Due to most of PVC soft rubber contain toxic plasticizer(Phthalates), Foreign markets of children toys is reject PVC, and the European Union(EN71) and the the United States standard(ASTMF963) which also limits the application of PVC in the toy industry.

Soft TPE/TPR material is based on SEBS, SBS.TPE, TPR soft rubber material has been recognized by more and more foreign company because they contains no plasticizer, halogen free environmental safety materials. What is more, most TPE/TPR manufacturers can provide the Environmental production test report.

TPE:A better choice for infusion tube

Intravenous infusion is the most commonly used method in clinical treatment, about 60%-70% of our hospital patients get treatment by intravenous infusion, about 80% of the emergency patients also get treatment by intravenous infusion.

Compared with other methods, intravenous infusion is the biggest risk way So the safety of intravenous infusion get more and more attention. There are many factors that affect the safety of clinical transfusion, and the material of the infusion device is an important link among them. 

Traditional PVC infusion has some defects,for example(1) Need to add plasticizer, generally DEHP (2) need to add  variety of metal ions as stabilizers, 
such as lead, cadmium, etc.(3) Dioxin can severely pollute the environm

Compared with the traditional PVC infusion, TPE infusion has the following characteristics(1)with no plasticizer-DEHP.  (2)with no stabilizers  (3) with no dioxin.

Brief introduction of environmentally friendly TPE materials: do not contain DEHP and other plasticizers, does not contain nonyl phenol (NP), 
does not contain polycyclic aromatic hydrocarbons PAHs, does not contain bisphenol A (BPA), without the addition of any stabilizer. TPE is 
a Environmentally friendly material.
