Deliver, Shipping And Serving

Before the sale, we confirm the demand for the product with the customer, and quote the customer according to the product drawings or product samples provided by the customer. After waiting for the customer to confirm the quotation, the company will open the mold order through the customer.The production of the test mode will be carried out, and the test mode can be completed in 20-30 days from the receipt of the order. After the customer confirms that the sample is OK, we will carry out mass production according to the order quantity, and the general delivery time is 3-7 days. After the sale, we will deal with the products with abnormal quality. If the products produced have quality problems, we will reply to the improvement report if the customer complains. If the products cannot be used, our company will arrange replenishment and finally meet the requirements of the customers.

Why do plastic products require so much color masterbatch

As the current "high performance plastic materials" promotion and popularization, the plastic products not only to the requirement of masterbatch to stay in this level, "color" of plastic industry, according to the product itself is different, also put forward corresponding requirements for masterbatch, this makes the masterbatch producer according to the market and application, developed into a series of masterbatch products with multiple compound functions. That is to say, color masterbatch this product, in providing plastic coloring this function, according to the application of plastic products, but also to provide plastic products such as "aging resistance", "heat resistance", "antibacterial", "enhancement" and other functional characteristics. The following is a breakdown of the major additional functions that black masterbatch can provide to illustrate which industrial applications in our real life batch provides irreplaceable assistance. I. uv protection automobile manufacturing: nowadays plastics have been widely used in automobile industry. Both inside and outside the car accessories, such as the piano lacquer that bake a beautiful instrument panel, matte imitation leather dashboard, solid and energy-absorbing bumper, etc., are inseparable from the contribution of black masterbatch, it not only provide the above car inner decoration with excellent colour performance, at the same time, as a commonly used ultraviolet absorption material, it also USES its own this feature, to act as automotive plastic umbrella, prevent ultraviolet damage to these beautiful car parts. Urban construction pipes and agricultural irrigation pipes: the transformation of urban pipe network and the national energy saving and emission reduction project for agricultural irrigation are also widely used in the industry of color masterbatch. Such as municipal water pipe, gas pipe, and western areas of agricultural water-saving drip irrigation pipe. The masterbatch not only provides coloring properties for these tubes, but also provides functions such as uv protection and antioxidant protection. Wire and cable industry: color masterbatch is widely used in high voltage overhead cable, communication cable cable and other cable plastic sheath materials, it has the effect of anti-oxygen and anti-uv. Geotechnical materials: color masterbatch is also widely used in geotechnical fabrics and geotechnical grille industry of laying highways to resist ultraviolet rays and increase the life span of geotechnical materials. 2, electrostatic protection function of electronic appliances manufacturing: for the microelectronics industry, the existence of static electricity is extremely harmful, it can break through the capacitor damage the electronic circuit, if not properly disposed, even because of circuit short circuit and cause fire hazards. We can take advantage of the conductivity of black pigment, "carbon black", and fundamentally solve the problem of the harm caused by static electricity. For example, the plastic trays and conductive carriers used by electronics factories, their production is by adding enough conductive black mother to obtain the required electrostatic conductivity, thus protecting the safety of electronic components. Mine mining industry: also, in the process of the mine mining, the harm of static electricity is bigger, it is the cause of gas explosion the culprit, so many underground facilities, all is the requirement of electrical conductivity, but the vast majority of plastic and is not conductive, through the conductive black mother of add, so that the conductive plastics with electrical conductivity, thus avoiding the harm of the static, achieve the goal of safe production. Of course, in addition to the above mentioned applications, black mother also has a variety of other USES, for example, people use carbon black pigment excellent hiding, in the process of plastic recycling, adding black mother to cover other colors, to achieve the purpose of waste utilization and saving resources. For another example, people take advantage of the high resistance of carbon black to light, which is used in the production of milk film. It blocks sunlight and achieves the effect of quasi-photodecomposition, which protects the milk and enables it to be stored for a longer time. Black mother in the plastic industry and its wide application, and our lives are closely linked. In addition, with the development of China's plastic industry in recent years, the color masterbatch industry has also achieved gratifying development results. At the same time, people have gradually realized that it is like an auxiliary material in a gluttonous feast for plastic processing, and its role cannot be underestimated. Although it is used in a small amount, it is also used once and for all.
