Tritan material used in infant supplies injection mold and its performance

Tritan material as the new favorite of food grade material, is the European Union specified as material for infants and young children, but domestic injection mold enterprise is not necessarily to know Tritan. In the smooth plastic products factory with his infant supplies injection mold manufacturing for years, and the strict requirements of customers for products material and escalating here to discuss the performance and application field of Tritan material. Domestic general plastic material we have the common PP, PS, ABS, PC,,,, these material I think everyone should not unfamiliar, shell of household appliances, auto parts, daily necessities, digital electronic products, building materials, these industries and no special requirements for products, just the materials good molding performance and low price to meet the enormous market demand. In addition, we have a lot of different industry products for its strength, high temperature resistant, environmental protection, insulation, etc have specific requirements. Such as smoothly reach in injection mould manufacturing often use Tritan, PPS, PA, PEEK, LCP special engineering plastics and so on. Model ten million kind of plastic material is different, I have to say the focus of this article is food grade material, other spoke again next time. What material is the material is food grade? Non-toxic, tasteless, odourless, conform to the hygienic standards for food packaging materials. Is domestic commonly used food grade PP, ABS, PC, PVC, PET,,,, etc. Although some plastic is food grade, but in refrigeration or heating under the condition of the molecular changes will decompose toxic or harmful substances to human body. Because people are the pursuit of quality of life and health, environmental requirements of the market of plastic raw materials also is increasing day by day, such as food grade PC, hydrolysis can produce BPA ( Bisphenol a - A) 。 In recent years, studies have shown that humans ( Including animal) Such as long-term intake of trace amounts of BPA, it is likely to have adverse influence on the reproductive system, destroy the balance of sex ratio, so some countries and regions have been limited or disable PC. Manufacturers face the environmental pressure, are looking for can replace the PC material, Eastman is under such market background, to develop a new generation of copolymerization Tritan. Due to various market requirements in the manufacture of injection mold is widely used. Tritan since early household items, and the application of small home appliance, 2014 years or so have been developed to more areas, including as a baby supplies, medical, cosmetics, outdoor and other applications, there are some other applications are being developed. By the us food and drug administration, FDA certification, baby products to Europe and the specified material. Tritan TX1001 resistance temperature can reach 99 degrees, do not contain BPA. Mainly used for space cup, coffee pot etc. Tritan TX2001 resistance temperature can reach 109 degrees, do not contain BPA. Mainly used in baby bottles. Compared to the production of plastic injection mould food grade PC, Tritan material light transmittance, impact resistance, hydrolysis resistance, resistance to high temperature can be comparable with PC, even more than. Injection molding conditions and their liquidity, shrinkage, sol temperature are almost, originally made of PC material injection mold without changing circumstances in Tritan is completely no problem. But the cost is higher, the Chinese had not for the material of FRP products is in line with the food grade test standards, general PC material GB14942 - or reference 1994 polycarbonate FRP products. So the domestic application less, supply is tight. But because it is the European Union is specified for infant supplies material, and so must appear on the tall, gradually will become the international general standard.
