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 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!

Does TPE soft rubber material stink?

Does TPE soft rubber material stink?  The TPE soft rubber formula is made of warm, non-corrosive and irritating raw materials to ensure the non-toxic safety of TPE soft rubber. TPE soft rubber material does not contain halogen, does not contain o-phenylene plasticizer, does not contain PAHs, does not contain nonylphenol NP, does not contain heavy metals and radioactive elements, does not contain bisphenol A, etc., in line with ROHs, REACH, EN71, FDA (water and alcohol testing) and other testing standards. TPE soft rubber material is also widely used, such as dining table mat, backpack base, foot pedal and so on. Wires and cables: cable jacket, connectors, plugs are covered, tool materials such as screwdrivers, hammers, wheels, etc., medical equipment: suction balls, instrument handles, wheels, straps, containers, gas masks, a variety of pipe fittings, corks, diving equipment, there are also many. So TPE soft rubber material will stink? 1. simply does not volatilize small molecules, such as table salt and other solids. But there is a smell only one possibility, that is, can volatilize small molecules, and small molecules have a smell. 2. The small molecules volatilized by the material itself have no smell, such as water. TPE soft rubber material will have some taste, but not odor. It is mainly due to the volatilization of small molecules from high temperature blending or processing components. tpe products processing. High-temperature injection molding, the smell is inevitable, the greater the oil content, the greater the smell. However, after the finished product is cooled, the odor of the product will slowly fade. Shangli Plastics is looking forward to your call!

What is the material of TPU phone case? Will it turn yellow?

What is the material of TPU phone case? Will it turn yellow? Many users will give the phone with a "jacket" (phone case), so that accidentally dropped, can largely reduce the damage, these cases are also a variety of materials, such as silicone, plastic, resin, TPU, etc.. Today, Shangri-Li is going to explain the knowledge of TPU material phone case, mainly to answer the question of what material is TPU phone case? Is it soft? Will it turn yellow? How to do if it turns yellow? What is TPU phone case material? Polyurethane thermoplastic elastomer (TPU), also known as polyurethane rubber, belongs to a class of elastic polymer materials containing more carbamate groups (-NHCOO-) in the molecular chain. It is a plastic material that can be softened or changed repeatedly under certain heat, while at room temperature it can keep its shape unchanged can play the role of support and protection, and is widely used in shoe materials, adhesives, pipes, films, synthetic leather, wires and cables, instrument panels, cell phone cases, medical bandages, etc. If you are careful enough, you can find it on the fabric logo of some clothes and shoes. With the enhanced performance of TPU materials, sports equipment and shoes are increasingly inclined to TPU products, especially UV-resistant and transparent materials. Therefore, TPU materials have great potential for development in the field of sporting goods and sports footwear materials. Is TPU phone case hard or soft? TPU cases are soft, but silicone is a little harder and stronger, TPU is a block copolymer, and the ratio of hard to soft components determines the performance of TPU. TPU has excellent flexibility and resilience, from very soft to very hard, from good flexibility to great rigidity, or from hydrophilic type that can absorb moisture to water-repellent type that repels water, and maintain high elasticity in a wide range of hardness (Shore A10-D75), and in the same hardness Under the same hardness than other elastomers bearing capacity. Will TPU phone case turn yellow? Yes, if you buy a light color case such as transparent or white, it will turn yellow after three or four months at most. But if it only turns yellow without fogging or sticking to your hands, it means the quality of TPU case you bought is still good. The TPU case becomes yellow how to do? Either change, or stickers, or turn a blind eye. TPU phone case yellowing and the choice of raw materials have a relationship, aliphatic anti-aging properties than aromatic some good, in addition, you can add antioxidants and anti-UV additives to improve the problem of yellowing. The above is about TPU cell phone case is what material? Is it soft? Although TPU phone case will turn yellow, I still choose TPU case because it has high transparency and high wear resistance, outstanding bearing capacity, impact resistance and shock absorption performance.
