What are the characteristics of TPE transparent materials? TPE transparent materials are of various types. Usually we use SEBS\SBS as the base material to blend and modify the new polymer elastomer material, which is called TPE or TPR. The approximate formula is SEBS\SBS+ rubber oil +PP+ functional additive. The hardness of TPE transparent material increases with the increase of PP (polypropylene) ratio.
Table of Performance Characteristics of TPE Transparent Material:
The hardness of transparent TPE material ranges from 0 to 0~120A, and the transparency decreases with the increase of hardness. The specific gravity is 0.84-0.89 g/cm3; If the specific gravity exceeds 1g/cm3, the filler is added. Shrinkage 1.2 ~ 1.5%; Melting finger 0.5 ~ 50g/10 min (2.16kg, 190 degrees); Elongation at break 400-1800%; The tensile strength is 3-12 MPa. TPE transparent material is recommended to be injection molded at 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 have a wide range of values, which gives our research and development personnel a lot of design space and allows you to develop it in a truly unconstrained manner.
TPE transparent material has the characteristics of environmental protection and non-toxicity, delicate and dry hand feeling, non-greasiness, good transparency and good elasticity, can be added with toner and color masterbatch, and fully complies with EU ROHS2.0；; REACH(SVHC),EN71-3, California 65 and other environmental standards.
Points for Attention in Selection of TPE Transparent Material Formula:
TPE transparent materials are also divided into three categories: highly transparent, fully transparent and semi-transparent. When producing highly transparent TPE materials, DeChong chemical technology developers suggest to use imported SEBS raw materials, such as Japan's Kolli kuraray and US's Koten Kraton's SEBS. The transparency of TPE materials made by Taiwan and domestic SEBS is not so good.
The selection of rubber oil in transparent TPE material formula is also very important. White oil with high hydrogenation degree has good yellowing resistance, and accordingly, has good transparency and is not easy to yellow. Some rubber oils turn yellow when made.
Applications 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 through injection molding, secondary injection molding, extrusion, blow molding and casting. Toys and daily necessities, stationery, sports equipment, sealing rings, car parts, handles, electrical appliances, sex toys, baby products and other fields can often see the figure of TPE transparent materials.What are the characteristics of TPE transparent materials?
