Halogen-free flame retardant TPU / TPE applications and technical problems in the field of wire and cable halogen-free flame retardant TPU / TPE in the field of wire and cable applications and technical problems 1. Price is undeniable that flame retardant TPE / TPU price is really high, more than 5 times the ordinary PVC. The price of the market are between 45-150 yuan / kg. Hard to get prices down in the short term, not the manufacturers do not want to, but the cost is to be placed there so much, such as raw materials in the flame going over 60 dollars a kilogram, generally account for about 30% of the proportion of the material itself , to the stability of the product, the manufacturer will choose super genuine brand products at home and pure SEBS TPU. The price is also high, the proportion accounted for about 50%. What surface treatment agents, slip agents and the like. In short, the high cost. This is a lot of end users is difficult to immediately switch causes a line in the cost, although the proportion of their share of the finished pitiful. 2. Precipitated product line so far, none of the world's material can be completely guaranteed no precipitation, including the right to Mann, Noveon, TSRC, plastic treasure. Specific features: face pale, a mist or surface Maoyou, shiny. These are the imbalance between large and small molecules after a period of time to squeeze out caused by macromolecules. With today's technology, this problem is still not resolved. Customers are advised to choose the best option when a slight whitish material surface, this precipitation will not affect its physical properties and electrical properties. Mao surface materials do not use, in use prone to fall off, peel. Further precipitation there is stress, good material which precipitates is mild, light, and in the short term is not likely to occur, even if the occurrence gently rub like http://mayu1991619.wjw.cn/ sheet extrusion machine http://ma1991619.wjw.cn/ calcium carbonate masterbatch pelletizing machine http://mayu1991619.kuyibu.com/product.html transparent barium sulfate Masterbatch granulator http://mayu1991619.cn .b2bhs.com / LSZH granulator http://mayu1991619.szc.com/ EPDM sheet extrusion machine http://mayu1991619.maijx.com barium sulfate filler granulator
