The melting temperature and enthalpy after the second heating run are mainly determined by the cooling rate of the previous step [22]. Additionally, Lubrizol offers harder TPU grades, in the shore hardness range of 50D to 70D, that have a high modulus of elasticity, and excellent low temperature impact strength. 305°CTin Coating = 150°C Max. 100-250. However, ETFE is Table 1: Types and Gauges of DuPont™ Tefzel® ETFE Fluoroplastic Film Gauge 50 100 200 500 Thickness, mil 0. 2% between 2021 and 2026ETFE is a semi-crystalline, melt processable thermoplastic that is essentially a 1:1 alternating copolymer of ethylene and tetrafluoroethylene. 76 Superior stress crack and mechanical properties at high temperature Tefzel® ETFE ETFE HT2185 150 2. More difficult to work with than PTFE Teflon. The mechanical properties of ETFE are superior to those of PTFE and FEP. Consequently, mechanical, dielectric and other properties of the product made from ETFE will be affected and toxic chemicals will be released when ETFE degrades at elevated temperatures [18]. At the melting point the solid and liquid phase exist in equilibrium. In the case of ETFE mixed with AP, the polyoxide may act as a nucleating agent for ETFE improving its crystallization. Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics. 5 K. 00 kg, Temperature 297 °C: 9. pH : No applicable data available. area factor, m2/kg 40 20 10 4 Availability Type LZ - ETFE, general-purpose X X X X Type CLZ - ETFE, one side cementable — X X XMaterials Overview. to diameter (24/1 up to 30/1 and beyond) and heaters should have the capacity to heat material to approximately 340°C. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa . 6 Hytrel® 4056 37 64 NY NY 26 500 152 -50 1. 4 Hytrel® 4068 33 45 NY NY 29 800 193 -55 1. The polymer maintains high impact strength in cryogenic applications. However, this paste-extruded fluoropolymer material is moreTefzel ™ ETFE HT-2183 and the other Tefzel fluoroplastics are melt processible, modified copolymers of ethylene and tetrafluoroethylene. As such, the operating temperature of the materials is lower. Irradiation temperature and linear energy transfer (LET) dependency on radiation-induced reactions of ethylene-co-tetrafluoroethylene polymer (ETFE) were investigated precisely by using low and high LET beams, and in a wide range of irradiation temperatures from 77 to 573 K including its melting temperature, respectively. 013, respectively.
