TPE,TPR material is maturely used in bicycle and motorcycle handlebar cover
TPE,TPR material is maturely used in bicycle and motorcycle handlebar cover Bicycle and motorcycle handlebars usually use a soft rubber material handlebar cover, this soft material handlebar cover has a soft feel, non-slip and other effects. This kind of soft material, the most common is soft PVC and rubber Soft PVC cost is relatively low, has a good elasticity and feel, but PVC for handlebar, there are two main defects, one is the low temperature resistance is poor, the temperature in -10 ~ -5 ℃, PVC easy to harden and gradually lose elasticity and feel; Second, most of the PVC toxic, containing halogen and toxic plasticizer phthalate, it is difficult to be competent in some high-end motorcycle bicycle handlebar cover. The rubber handlebar cover has better mechanical strength and wear resistance, long service life. But rubber needs to be vulcanized, the production cycle is long, and the material is difficult to recycle, is also a headache for users. The development of thermoplastic elastomer TPE / TPR in recent years can be described as a rapid development, in all walks of life, repeatedly show their skills, multiplied by the rubber and plastic industry attention. Its many advantages, making it an alternative to traditional PVC and rubber, handy in a variety of bicycle and motorcycle handlebar cover. TPE and TPR are thermoplastic materials, which can be injection molded quickly without vulcanization, so that the production cycle can be calculated in seconds instead of minutes for rubber. Advantage 2: Environmentally friendly material. Compared with vulcanized rubber materials, TPE/TPR can be 100% recycled and reused to protect the environment. Advantage 3: Excellent low temperature resistance. Relative to PVC, TPE/TPR low temperature resistance can be in -50 ℃ low temperature still maintain the elastic properties of the hard, still has excellent elasticity and soft touch. Advantage 4: thermoplastic rubber TPE/TPR does not contain halogen, does not contain toxic o-phenyl plasticizers, does not contain heavy metals, etc., is an excellent environmental protection materials. The following are some of our main cases of TPE/TPR used as bicycle and motorcycle handlebar cover. 1. All the materials are made of TPE/TPR, individually injection molding, hardness depends on customer requirements. 2. TPE, TPR and hard plastic cover glue bonding, hard plastic is usually PP, ABS or PA nylon. 3. There is also a more high-end bicycle handlebar cover, the use of soft TPR (such as 15 ~ 30 degrees) with hard TPR (hardness in 75 ~ 90A), soft and hard TPR material is usually used in two colors.

What is the processing temperature and molding temperature of TPE
What is the processing temperature and molding temperature of TPE Depends on the hardness of TPE, generally soft material 150-190 degrees Celsius, high hardness 180-240 degrees Celsius processing temperature. TPE is also known as triethyl phosphate, TPE-Triethyl phosphate state is a colorless and non-flammable liquid, slightly hygroscopic, stable at room temperature, soluble in alcohols, ethers and a variety of organic solvents, soluble in water, but decomposed with the increase in temperature, boiling point 216 degrees Celsius. It is used as chemical reagent, catalyst for production of acetic anhydride and diethylene ketone, nitrocellulose and cellulose acetate solvent, synthetic resin plasticizer, organic insecticide stabilizer, ethyl agent, chemical synthesis intermediate, lubricant additive, resin flame retardant.

What to pay attention to in TPE covered ABS
What to pay attention to in TPE covered ABS TPE covered ABS products have good applications in various industries. Sometimes there are some bad phenomena after the production of encapsulation out, the following analysis of TPE encapsulation ABS what problems are likely to occur? 1, the phenomenon of lack of glue. This is mostly due to the processing process, processing temperature and pressure are not high enough. So we should raise the injection temperature and increase the injection pressure. 2, the product produced by overmolding has poor adhesion. This is mainly due to the unreasonable production formula before processing, and the injection temperature is not high enough. Therefore, we should pay attention to improve the injection temperature and adjust the appropriate formula. 3, its appearance is not smooth, nor shiny. This is mainly the raw material moisture is not enough, the processing temperature is not enough to produce. Therefore, when wrapping and processing again, the injection processing temperature should be increased and the moisture of raw materials should be reduced. 4, in the manufacturing process, it will appear to stick to the mold phenomenon. At this time we add some mold release agent will be able to prevent its sticky mold. 5, the surface cleanliness of ABS products, TPE material preheating before processing, the choice of color powder or masterbatch has a certain impact on the adhesion of TPE and ABS package.

How to set the injection parameters of TPE material
How to set the injection parameters of TPE material As a TPE manufacturer in Dongguan, the following is an introduction to the parameters of TPE injection molding to supply the friends who need to know. Because TPE material has the performance of rubber and the processing method of PVC, TPE material can be processed and molded with general injection molding grade, without special machinery and equipment, and the molding cycle is short. Rubber is hot demoulding, TPE material is cold demoulding, so the two materials are different processing methods. TPE injection molding processing parameters depend on the type of TPE, grade (formula design) and product structure and other factors, because each TPE manufacturer's material formula is different, the material shrinkage rate, circulation and so on are different, and the structure of the product, mold design have a lot to do with the specific processing parameters should refer to the material supplier's physical properties table! We are a free to customize different material formulations for customers to create a more cost-effective TPE, TPU, TPV, TPR, TPV raw materials, with unique performance, excellent quality has been recognized by the majority of customers!

Is TPR material toxic?
Is TPR material toxic? TPR material is a thermoplastic rubber material. It is a kind of thermoplastic soft rubber material with rubber elasticity 5261 and without vulcanization, which can be directly processed and molded (such as injection molding, extrusion 1653, blow molding, etc.). TPR material is based on thermoplastic styrene-butadiene rubber as the basic raw material, adding resin (such as PP, PS), fillers, plasticizing oil agent and other functional additives blended modified materials. The use temperature range is -45~90℃. Usually TPR material is based on SBS base material, its chemical properties are as follows: weather resistance, aging resistance in general, temperature resistance 70~75℃. If you need good aging resistance and temperature resistance, you can choose the modified material of SEBS base material. Extended information. TPR and PVC are both soft materials with rubber elasticity, which are difficult to identify through appearance and feel. And the difference by burning is more intuitive and easy. 1, look at the burning smell. tpr burning aromatic smell, the taste is not unpleasant. pvc burning chlorine odor, the taste is unpleasant. 2, look at the flame color. Burning flame root color green is PVC material, the color of blue is TPR material. 3, flame retardant level (refers to the material without flame retardants) PVC flame retardant level UL94-V2, with self-extinguishing, ignition combustion, ignition source evacuation, the flame will generally be extinguished; TPR flame retardant level UL94-HB, burning in the fire, away from the fire continues to burn does not go out. TPR material is widely used in daily-use products, hardware tools, luggage wheels, sports equipment, toy products, auto parts, medical products, wire and cable, electronic appliances, communication instruments and shoe products, etc.. The shoes and toys industry is mainly the application area of TPR with SBS base material, and the modified material with SEBS base material is mainly used in the application of aging resistance, weather resistance, high material tensile strength, and ultra-low material hardness (less than 5 degrees Shore hardness).
