What are the characteristics of TPE transparent materials? There are many kinds of TPE transparent materials. Usually, we use SEBS\SBS as the base material to blend and modify new materials with high scores, which are called TPE or TPR. The approximate formula is SEBS\SBS+ rubber oil +PP+ functional additives. The hardness of TPE transparent material increases with the increase of PP (polypropylene) ratio. Table of performance characteristics of TPE transparent materials: The hardness of transparent TPE materials ranges from 0 to 120 A, and the transparency will decrease with the increase of hardness. Specific gravity 0.84 ~ 0.89 g/cm3; Those with specific gravity exceeding 1g/cm3 are filled with fillers. The shrinkage rate is 1.2-1.5%; Melting finger 0.5 ~ 50g/10min (2.16kg, 190 degrees); The elongation at break is 400-1800%; The tensile strength is 3~12MPa. The recommended injection molding temperature for TPE transparent materials is 150~200℃. We can see from the above performance characteristic table that its hardness, specific gravity, shrinkage, melt index, elongation at break and other physical properties range is very wide, which gives our R&D personnel a lot of design space, and it is really free for you to develop. TPE transparent material has the characteristics of environmental protection and non-toxicity, delicate and dry hand feeling, non-greasy, good transparency and good elasticity, and can be added with toner and masterbatch to match colors, which fully conforms to EU ROHS2.0；; Environmental protection standards such as REACH(SVHC),EN71-3 and California 65. Points for attention in selecting TPE transparent material formula; TPE transparent materials are also divided into three categories: high transparency, full transparency and translucency. when producing high transparency TPE materials, dechuang chemical technology developers suggest to use imported SEBS raw materials, such as kuraray from Japan and SEBS from Kraton from America. The transparency of TPE materials made by SEBS in Taiwan and China is not so good. The choice of rubber oil in transparent TPE material formula is also very important. White oil with high hydrogenation degree has good yellowing resistance, and accordingly, it has good transparency and is not easy to yellow. Some rubber oils will turn yellow when made. Application fields of TPE transparent materials: TPE transparent material has the above characteristics, so it is widely used and has various processing technologies. It can be molded by injection molding, secondary injection molding, extrusion, blow molding and pouring. TPE transparent materials can often be seen in toys and daily necessities, stationery, sports equipment, sealing rings, auto parts, handles, electrical appliance housings, sex toys and baby products.
